++After installing the dependencies for SINGA and PySINGA, please download the correct binary:
++
++ # Ubuntu/Linux 64-bit, CPU only, Python 2.7, Protobuf 2.5
++ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.5/singa-1.0.0-cp27-none-linux_x86_64.whl
++
++ # Ubuntu/Linux 64-bit, CPU only, Python 2.7, Protobuf 2.6
++ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.6/singa-1.0.0-cp27-none-linux_x86_64.whl
++
++ # Ubuntu/Linux 64-bit, GPU enabled, Python 2.7, Protobuf 2.5, CUDA toolkit 7.5 and CuDNN v5
++ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.5-cuda7.5-cudnn5/singa-1.0.0-cp27-none-linux_x86_64.whl
++
++ # Ubuntu/Linux 64-bit, GPU enabled, Python 2.7, Protobuf 2.6, CUDA toolkit 7.5 and CuDNN v5
++ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.6-cuda7.5-cudnn5/singa-1.0.0-cp27-none-linux_x86_64.whl
++
++Then, run the following command
++
++ $ sudo pip install --upgrade $SINGA_WHEEL_URL
++
++If you do not have sudo right, you can run `pip install` in a python virtual environment.
++
++
++### From source
++
++Please compile SINGA from source (see the next section) with the 'USE_PYTHON' option on,
++and then run the following commands,
++
++ # under the build directory
++ $ cd python
++ $ sudo pip install .
++
++If you are using a virtual environment, you can ignore the `sudo` keyword.
++
++Developers can build the wheel file via
++
++ # under the build directory
++ $ cd python
++ $ python setup.py bdist_wheel
++
++
++The generated wheel file is under "dist" directory
++
++
++## Build SINGA from source
++
++Please clone the newest code from [Github](https://github.com/apache/incubator-singa) and execute the following commands,
++
++ $ git clone https://github.com/apache/incubator-singa.git
++ $ cd incubator-singa/
++
++If you use CUDA, then [CNMeM](https://github.com/NVIDIA/cnmem) is necessary,
++which could be downloaded as
++
++ $ git submodule init
++ $ git submodule update
++
++
++### Linux & MacOS
++
++GCC (>=4.8.1) is required to compile SINGA on Linux.
++For Mac OS users, you can use either GCC or Clang.
++
++In SINGA_ROOT, execute the following commands for compiling SINGA,
++
++ $ mkdir build && cd build
++ $ cmake ..
++ $ make
++ $ make install
++
++Note that if you are using CUDNN and it is not installed under system default
++folder, you need to let cmake know the paths to CUDNN,
++
++ $ export CMAKE_INCLUDE_PATH=<path to cudnn>/include:$CMAKE_INCLUDE_PATH
++ $ export CMAKE_LIBRARY_PATH=<path to cudnn>/lib64:$CMAKE_LIBRARY_PATH
++
++You can use `ccmake ..` to configure the compilation options including using
++generating python binding and changing the installation folder.
++If the dependent libraries are not in the system default paths, you need to export
++the following environment variables
++
++ export CMAKE_INCLUDE_PATH=<path to your header file folder>
++ export CMAKE_LIBRARY_PATH=<path to your lib file folder>
++
++After compiling SINGA, you can run the unit tests by
++
++ $ ./bin/test_singa
++
++You can see all the testing cases with testing results. If SINGA passes all
++tests, then you have successfully installed SINGA. Please proceed to try the examples!

++
++## FAQ
++
++* Q: Error from running `cmake ..`, which cannot find the dependent libraries.
++
++ A: If you haven't installed the libraries, please install them. If you installed
++ the libraries in a folder that is outside of the system folder, e.g. /usr/local,
++ please export the following variables
++
++ export CMAKE_INCLUDE_PATH=<path to your header file folder>
++ export CMAKE_LIBRARY_PATH=<path to your lib file folder>
++
++
++* Q: Error from `make`, e.g. the linking phase
++
++ A: If your libraries are in other folders than system default paths, you need
++ to export the following varaibles
++
++ $ export LIBRARY_PATH=<path to your lib file folder>
++ $ export LD_LIBRARY_PATH=<path to your lib file folder>
++
++
++* Q: Error from header files, e.g. 'cblas.h no such file or directory exists'
++
++ A: You need to include the folder of the cblas.h into CPLUS_INCLUDE_PATH,
++ e.g.,
++
++ $ export CPLUS_INCLUDE_PATH=/opt/OpenBLAS/include:$CPLUS_INCLUDE_PATH
++
++* Q:While compiling SINGA, I get error `SSE2 instruction set not enabled`
++
++ A:You can try following command:
++
++ $ make CFLAGS='-msse2' CXXFLAGS='-msse2'
++
++* Q:I get `ImportError: cannot import name enum_type_wrapper` from google.protobuf.internal when I try to import .py files.
++
++ A: You need to install the python binding of protobuf, which could be installed via
++
++ $ sudo apt-get install protobuf
++
++ or from source
++
++ $ cd /PROTOBUF/SOURCE/FOLDER
++ $ cd python
++ $ python setup.py build
++ $ python setup.py install
++
++* Q: When I build OpenBLAS from source, I am told that I need a Fortran compiler.
++
++ A: You can compile OpenBLAS by
++
++ $ make ONLY_CBLAS=1
++
++ or install it using
++
++ $ sudo apt-get install libopenblas-dev
++
++* Q: When I build protocol buffer, it reports that GLIBC++_3.4.20 not found in /usr/lib64/libstdc++.so.6.
++
++ A9: This means the linker found libstdc++.so.6 but that library
++ belongs to an older version of GCC than was used to compile and link the
++ program. The program depends on code defined in
++ the newer libstdc++ that belongs to the newer version of GCC, so the linker
++ must be told how to find the newer libstdc++ shared library.
++ The simplest way to fix this is to find the correct libstdc++ and export it to
++ LD_LIBRARY_PATH. For example, if GLIBC++_3.4.20 is listed in the output of the
++ following command,
++
++ $ strings /usr/local/lib64/libstdc++.so.6|grep GLIBC++
++
++ then you just set your environment variable as
++
++ $ export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
++
++* Q: When I build glog, it reports that "src/logging_unittest.cc:83:20: error: \u2018gflags\u2019 is not a namespace-name"
++
++ A: It maybe that you have installed gflags with a different namespace such as "google". so glog can't find 'gflags' namespace.
++ Because it is not necessary to have gflags to build glog. So you can change the configure.ac file to ignore gflags.
++
++ 1. cd to glog src directory
++ 2. change line 125 of configure.ac to "AC_CHECK_LIB(gflags, main, ac_cv_have_libgflags=0, ac_cv_have_libgflags=0)"
++ 3. autoreconf
++
++ After this, you can build glog again.

+Device
+=======
+
+
+The Device abstract represents any hardware device with memory and compuation units.
+All [Tensor operations](tensor.html) are scheduled by the resident device for execution.
+Tensor memory is also managed by the device's memory manager. Therefore, optimization
+of memory and execution are implemented in the Device class.
+
+Specific devices
+----------------
+Currently, SINGA has three Device implmentations,
+
+1. CudaGPU for an Nvidia GPU card which runs Cuda code
+2. CppCPU for a CPU which runs Cpp code
+3. OpenclGPU for a GPU card which runs OpenCL code

+# Software Stack
+
+SINGA's software stack includes three major components, namely, core, IO and
+model. Figure 1 illustrates these components together with the hardware.
+The core component provides memory management and tensor operations;
+IO has classes for reading (and writing) data from (to) disk and network; The
+model component provides data structures and algorithms for machine learning models,
+e.g., layers for neural network models, optimizers/initializer/metric/loss for
+general machine learning models.
+
+
+<img src="../_static/images/singav1-sw.png" align="center" width="500px"/>
+<br/>
+<span><strong>Figure 1 - SINGA V1 software stack.</strong></span>
+
+## Core
+
+[Tensor](tensor.html) and [Device](device.html) are two core abstractions in SINGA. Tensor class represents a
+multi-dimensional array, which stores model variables and provides linear algebra
+operations for machine learning
+algorithms, including matrix multiplication and random functions. Each tensor
+instance (i.e. a tensor) is allocated on a Device instance.
+Each Device instance (i.e. a device) is created against one hardware device,
+e.g. a GPU card or a CPU core. Devices manage the memory of tensors and execute
+tensor operations on its execution units, e.g. CPU threads or CUDA streams.
+
+Depending on the hardware and the programming language, SINGA have implemented
+the following specific device classes:
+
+* **CudaGPU** represents an Nvidia GPU card. The execution units are the CUDA streams.
+* **CppCPU** represents a normal CPU. The execution units are the CPU threads.
+* **OpenclGPU** represents normal GPU card from both Nvidia and AMD.
+ The execution units are the CommandQueues. Given that OpenCL is compatible with
+ many hardware devices, e.g. FPGA and ARM, the OpenclGPU has the potential to be
+ extended for other devices.
+
+Different types of devices use different programming languages to write the kernel
+functions for tensor operations,
+
+* CppMath (tensor_math_cpp.h) implements the tensor operations using Cpp for CppCPU
+* CudaMath (tensor_math_cuda.h) implements the tensor operations using CUDA for CudaGPU
+* OpenclMath (tensor_math_opencl.h) implements the tensor operations using OpenCL for OpenclGPU
+
+In addition, different types of data, such as float32 and float16, could be supported by adding
+the corresponding tensor functions.
+
+Typically, users would create a device instance and pass it to create multiple
+tensor instances. When users call the Tensor functions, these function would invoke
+the corresponding implementation (CppMath/CudaMath/OpenclMath) automatically. In
+other words, the implementation of Tensor operations is transparent to users.
+
+Most machine learning algorithms could be expressed using (dense or sparse) tensors.
+Therefore, with the Tensor abstraction, SINGA would be able to run a wide range of models,
+including deep learning models and other traditional machine learning models.
+
+The Tensor and Device abstractions are extensible to support a wide range of hardware device
+using different programming languages. A new hardware device would be supported by
+adding a new Device subclass and the corresponding implementation of the Tensor
+operations (xxxMath).
+
+Optimizations in terms of speed and memory could be implemented by Device, which
+manages both operation execution and memory malloc/free. More optimization details
+would be described in the [Device page](device.html).
+
+
+## Model
+
+On top of the Tensor and Device abstractions, SINGA provides some higher level
+classes for machine learning modules.
+
+* [Layer](layer.html) and its subclasses are specific for neural networks. Every layer provides
+ functions for forward propagating features and backward propagating gradients w.r.t the training loss functions.
+ They wraps the complex layer operations so that users can easily create neural nets
+ by connecting a set of layers.
+
+* [Initializer](initializer.html) and its subclasses provide variant methods of initializing
+ model parameters (stored in Tensor instances), following Uniform, Gaussian, etc.
+
+* [Loss](loss.html) and its subclasses defines the training objective loss functions.
+ Both functions of computing the loss values and computing the gradient of the prediction w.r.t the
+ objective loss are implemented. Example loss functions include squared error and cross entropy.
+
+* [Metric](metric.html) and its subclasses provide the function to measure the
+ performance of the model, e.g., the accuracy.
+
+* [Optimizer](optimizer.html) and its subclasses implement the methods for updating
+ model parameter values using parameter gradients, including SGD, AdaGrad, RMSProp etc.
+
+
+## IO
+
+The IO module consists of classes for data loading, data preprocessing and message passing.
+
+* Reader and its subclasses load string records from disk files
+* Writer and its subclasses write string records to disk files
+* Encoder and its subclasses encode Tensor instances into string records
+* Decoder and its subclasses decodes string records into Tensor instances
+* Endpoint represents a communication endpoint which provides functions for passing messages to each other.
+* Message represents communication messages between Endpoint instances. It carries both meta data and payload.

+Tensor
+========
+
+Each Tensor instance is a multi-dimensional array allocated on a specific
+Device instance. Tensor instances store variables and provide
+linear algebra operations over different types of hardware devices without user
+awareness. Note that users need to make sure the tensor operands are
+allocated on the same device except copy functions.
+
+
+Tensor implementation
+---------------------
+
+SINGA has three different sets of implmentations of Tensor functions, one for each
+type of Device.
+
+* 'tensor_math_cpp.h' implements operations using Cpp (with CBLAS) for CppGPU devices.
+* 'tensor_math_cuda.h' implements operations using Cuda (with cuBLAS) for CudaGPU devices.
+* 'tensor_math_opencl.h' implements operations using OpenCL for OpenclGPU devices.
+
+Python API
+----------
+
+There are two set of tensor functions,
+1. Tensor member functions, which would change the internal state of the Tensor instance.
+2. tensor module functions, which accepts Tensor instances as arguments and return
+Tensor instances.

Apache SINGA is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

-# Python Binding
-
----
-
-Python binding provides APIs for configuring a training job following
-[keras](http://keras.io/), including the configuration of neural net, training
-algorithm, etc. It replaces the configuration file (e.g., *job.conf*) in
-protobuf format, which is typically long and error-prone to prepare. In later
-version, we will add python functions to interact with the layer and neural net
-objects, which would enable users to train and debug their models
-interactively.
-
-Here is the layout of python related code,
-
- SINGAROOT/tool/python
- |-- pb2 (has job_pb2.py)
- |-- singa
- |-- model.py
- |-- layer.py
- |-- parameter.py
- |-- initialization.py
- |-- utils
- |-- utility.py
- |-- message.py
- |-- examples
- |-- cifar10_cnn.py, mnist_mlp.py, , mnist_rbm1.py, mnist_ae.py, etc.
- |-- datasets
- |-- cifar10.py
- |-- mnist.py
-
-## Compiling and running instructions
-
-In order to use the Python APIs, users need to add the following arguments when compiling
-SINGA,
-
- ./configure --enable-python --with-python=PYTHON_DIR
- make
-
-where PYTHON_DIR has Python.h
-
-
-The training program is launched by
-
- bin/singa-run.sh -exec <user_main.py>
-
-where user_main.py creates the JobProto object and passes it to Driver::Train to
-start the training.
-
-For example,
-
- cd SINGAROOT
- bin/singa-run.sh -exec tool/python/examples/cifar10_cnn.py
-
-
-
-## Examples
-
-
-### MLP Example
-
-This example uses python APIs to configure and train a MLP model over the MNIST
-dataset. The configuration content is the same as that written in *SINGAROOT/examples/mnist/job.conf*.
-
-```
-X_train, X_test, workspace = mnist.load_data()
-
-m = Sequential('mlp', sys.argv)
-
-m.add(Dense(2500, init='uniform', activation='tanh'))
-m.add(Dense(2000, init='uniform', activation='tanh'))
-m.add(Dense(1500, init='uniform', activation='tanh'))
-m.add(Dense(1000, init='uniform', activation='tanh'))
-m.add(Dense(500, init='uniform', activation='tanh'))
-m.add(Dense(10, init='uniform', activation='softmax'))
-
-sgd = SGD(lr=0.001, lr_type='step')
-topo = Cluster(workspace)
-m.compile(loss='categorical_crossentropy', optimizer=sgd, cluster=topo)
-m.fit(X_train, nb_epoch=1000, with_test=True)
-result = m.evaluate(X_test, batch_size=100, test_steps=10, test_freq=60)
-```
-
-### CNN Example
-
-This example uses python APIs to configure and train a CNN model over the Cifar10
-dataset. The configuration content is the same as that written in *SINGAROOT/examples/cifar10/job.conf*.
-
-
-```
-X_train, X_test, workspace = cifar10.load_data()
-
-m = Sequential('cnn', sys.argv)
-
-m.add(Convolution2D(32, 5, 1, 2, w_std=0.0001, b_lr=2))
-m.add(MaxPooling2D(pool_size=(3,3), stride=2))
-m.add(Activation('relu'))
-m.add(LRN2D(3, alpha=0.00005, beta=0.75))
-
-m.add(Convolution2D(32, 5, 1, 2, b_lr=2))
-m.add(Activation('relu'))
-m.add(AvgPooling2D(pool_size=(3,3), stride=2))
-m.add(LRN2D(3, alpha=0.00005, beta=0.75))
-
-m.add(Convolution2D(64, 5, 1, 2))
-m.add(Activation('relu'))
-m.add(AvgPooling2D(pool_size=(3,3), stride=2))
-
-m.add(Dense(10, w_wd=250, b_lr=2, b_wd=0, activation='softmax'))
-
-sgd = SGD(decay=0.004, lr_type='manual', step=(0,60000,65000), step_lr=(0.001,0.0001,0.00001))
-topo = Cluster(workspace)
-m.compile(updater=sgd, cluster=topo)
-m.fit(X_train, nb_epoch=1000, with_test=True)
-result = m.evaluate(X_test, 1000, test_steps=30, test_freq=300)
-```
-
-
-### RBM Example
-
-This example uses python APIs to configure and train a RBM model over the MNIST
-dataset. The configuration content is the same as that written in *SINGAROOT/examples/rbm*.conf*.
-
-```
-rbmid = 3
-X_train, X_test, workspace = mnist.load_data(nb_rbm=rbmid)
-m = Energy('rbm'+str(rbmid), sys.argv)
-
-out_dim = [1000, 500, 250]
-m.add(RBM(out_dim, w_std=0.1, b_wd=0))
-
-sgd = SGD(lr=0.1, decay=0.0002, momentum=0.8)
-topo = Cluster(workspace)
-m.compile(optimizer=sgd, cluster=topo)
-m.fit(X_train, alg='cd', nb_epoch=6000)
-```
-
-### AutoEncoder Example
-This example uses python APIs to configure and train an autoencoder model over
-the MNIST dataset. The configuration content is the same as that written in
-*SINGAROOT/examples/autoencoder.conf*.
-
-
-```
-rbmid = 4
-X_train, X_test, workspace = mnist.load_data(nb_rbm=rbmid+1)
-m = Sequential('autoencoder', sys.argv)
-
-hid_dim = [1000, 500, 250, 30]
-m.add(Autoencoder(hid_dim, out_dim=784, activation='sigmoid', param_share=True))
-
-agd = AdaGrad(lr=0.01)
-topo = Cluster(workspace)
-m.compile(loss='mean_squared_error', optimizer=agd, cluster=topo)
-m.fit(X_train, alg='bp', nb_epoch=12200)
-```
-
-### To run SINGA on GPU
-
-Users need to set a list of gpu ids to `device` field in fit() or evaluate().
-The number of GPUs must be the same to the number of workers configured for
-cluster topology.
-
-
-```
-gpu_id = [0]
-m.fit(X_train, nb_epoch=100, with_test=True, device=gpu_id)
-```
-
-### TIPS
-
-Hidden layers for MLP can be configured as
-
-```
-for n in [2500, 2000, 1500, 1000, 500]:
- m.add(Dense(n, init='uniform', activation='tanh'))
-m.add(Dense(10, init='uniform', activation='softmax'))
-```
-
-Activation layer can be specified separately
-
-```
-m.add(Dense(2500, init='uniform'))
-m.add(Activation('tanh'))
-```
-
-Users can explicitly specify hyper-parameters of weight and bias
-
-```
-par = Parameter(init='uniform', scale=0.05)
-m.add(Dense(2500, w_param=par, b_param=par, activation='tanh'))
-m.add(Dense(2000, w_param=par, b_param=par, activation='tanh'))
-m.add(Dense(1500, w_param=par, b_param=par, activation='tanh'))
-m.add(Dense(1000, w_param=par, b_param=par, activation='tanh'))
-m.add(Dense(500, w_param=par, b_param=par, activation='tanh'))
-m.add(Dense(10, w_param=par, b_param=par, activation='softmax'))
-```
-
-
-```
-parw = Parameter(init='gauss', std=0.0001)
-parb = Parameter(init='const', value=0)
-m.add(Convolution(32, 5, 1, 2, w_param=parw, b_param=parb, b_lr=2))
-m.add(MaxPooling2D(pool_size(3,3), stride=2))
-m.add(Activation('relu'))
-m.add(LRN2D(3, alpha=0.00005, beta=0.75))
-
-parw.update(std=0.01)
-m.add(Convolution(32, 5, 1, 2, w_param=parw, b_param=parb))
-m.add(Activation('relu'))
-m.add(AvgPooling2D(pool_size(3,3), stride=2))
-m.add(LRN2D(3, alpha=0.00005, beta=0.75))
-
-m.add(Convolution(64, 5, 1, 2, w_param=parw, b_param=parb, b_lr=1))
-m.add(Activation('relu'))
-m.add(AvgPooling2D(pool_size(3,3), stride=2))
-
-m.add(Dense(10, w_param=parw, w_wd=250, b_param=parb, b_lr=2, b_wd=0, activation='softmax'))
-```
-
-
-Data can be added in this way,
-
-```
-X_train, X_test = mnist.load_data() // parameter values are set in load_data()
-m.fit(X_train, ...) // Data layer for training is added
-m.evaluate(X_test, ...) // Data layer for testing is added
-```
-or this way,
-
-```
-X_train, X_test = mnist.load_data() // parameter values are set in load_data()
-m.add(X_train) // explicitly add Data layer
-m.add(X_test) // explicitly add Data layer
-```
-
-
-```
-store = Store(path='train.bin', batch_size=64, ...) // parameter values are set explicitly
-m.add(Data(load='recordinput', phase='train', conf=store)) // Data layer is added
-store = Store(path='test.bin', batch_size=100, ...) // parameter values are set explicitly
-m.add(Data(load='recordinput', phase='test', conf=store)) // Data layer is added
-```
-
-
-### Cases to run SINGA
-
-(1) Run SINGA for training
-
-```
-m.fit(X_train, nb_epoch=1000)
-```
-
-(2) Run SINGA for training and validation
-
-```
-m.fit(X_train, validate_data=X_valid, nb_epoch=1000)
-```
-
-(3) Run SINGA for test while training
-
-```
-m.fit(X_train, nb_epoch=1000, with_test=True)
-result = m.evaluate(X_test, batch_size=100, test_steps=100)
-```
-
-(4) Run SINGA for test only
-Assume a checkpoint exists after training
-
-```
-result = m.evaluate(X_test, batch_size=100, checkpoint_path=workspace+'/checkpoint/step100-worker0')
-```

-## Implementation Details
-
-### Layer class (inherited)
-
-* Data
-* Dense
-* Activation
-* Convolution2D
-* MaxPooling2D
-* AvgPooling2D
-* LRN2D
-* Dropout
-* RBM
-* Autoencoder
-
-### Model class
-
-Model class has `jobconf` (JobProto) and `layers` (layer list)
-
-Methods in Model class
-
-* add
- * add Layer into Model
- * 2 subclasses: Sequential model and Energy model
-
-* compile
- * set Updater (i.e., optimizer) and Cluster (i.e., topology) components
-
-* fit
- * set Training data and parameter values for the training
- * (optional) set Validatiaon data and parameter values
- * set Train_one_batch component
- * specify `with_test` field if a user wants to run SINGA with test data simultaneously.
- * [TODO] recieve train/validation results, e.g., accuracy, loss, ppl, etc.
-
-* evaluate
- * set Testing data and parameter values for the testing
- * specify `checkpoint_path` field if a user want to run SINGA only for testing.
- * [TODO] recieve test results, e.g., accuracy, loss, ppl, etc.
-
-### Results
-
-fit() and evaluate() return train/test results, a dictionary containing
-
-* [key]: step number
-* [value]: a list of dictionay
- * 'acc' for accuracy
- * 'loss' for loss
- * 'ppl' for ppl
- * 'se' for squred error
-
-
-### Parameter class
-
-Users need to set parameter and initial values. For example,
-
-* Parameter (fields in Param proto)
- * lr = (float) // learning rate multiplier, used to scale the learning rate when updating parameters.
- * wd = (float) // weight decay multiplier, used to scale the weight decay when updating parameters.
-
-* Parameter initialization (fields in ParamGen proto)
- * init = (string) // one of the types, 'uniform', 'constant', 'gaussian'
- * high = (float) // for 'uniform'
- * low = (float) // for 'uniform'
- * value = (float) // for 'constant'
- * mean = (float) // for 'gaussian'
- * std = (float) // for 'gaussian'
-
-* Weight (`w_param`) is 'gaussian' with mean=0, std=0.01 at default
-
-* Bias (`b_param`) is 'constant' with value=0 at default
-
-* How to update the parameter fields
- * for updating Weight, put `w_` in front of field name
- * for updating Bias, put `b_` in front of field name
-
-Several ways to set Parameter values
-
-```
-parw = Parameter(lr=2, wd=10, init='gaussian', std=0.1)
-parb = Parameter(lr=1, wd=0, init='constant', value=0)
-m.add(Convolution2D(10, w_param=parw, b_param=parb, ...)
-```
-
-```
-m.add(Dense(10, w_mean=1, w_std=0.1, w_lr=2, w_wd=10, ...)
-```
-
-```
-parw = Parameter(init='constant', mean=0)
-m.add(Dense(10, w_param=parw, w_lr=1, w_wd=1, b_value=1, ...)
-```
-
-### Other classes
-
-* Store
-* Algorithm
-* Updater
-* SGD
-* AdaGrad
-* Cluster

-Introduction
-==============
-
-
-SINGA is a general distributed deep learning platform for training big deep
-learning models over large datasets. It is designed with an intuitive
-programming model based on the layer abstraction. A variety
-of popular deep learning models are supported, namely feed-forward models including
-convolutional neural networks (CNN), energy models like restricted Boltzmann
-machine (RBM), and recurrent neural networks (RNN). Many built-in layers are
-provided for users. SINGA architecture is
-sufficiently flexible to run synchronous, asynchronous and hybrid training
-frameworks. SINGA
-also supports different neural net partitioning schemes to parallelize the
-training of large models, namely partitioning on batch dimension, feature
-dimension or hybrid partitioning.
-
-
-Goals
------
-
-As a distributed system, the first goal of SINGA is to have good scalability. In other
-words, SINGA is expected to reduce the total training time to achieve certain
-accuracy with more computing resources (i.e., machines).
-
-
-The second goal is to make SINGA easy to use.
-It is non-trivial for programmers to develop and train models with deep and
-complex model structures. Distributed training further increases the burden of
-programmers, e.g., data and model partitioning, and network communication. Hence it is essential to
-provide an easy to use programming model so that users can implement their deep
-learning models/algorithms without much awareness of the underlying distributed
-platform.
-
-Principles
-----------
-
-Scalability is a challenging research problem for distributed deep learning
-training. SINGA provides a general architecture to exploit the scalability of
-different training frameworks. Synchronous training frameworks improve the
-efficiency of one training iteration, and
-asynchronous training frameworks improve the convergence rate. Given a fixed budget
-(e.g., cluster size), users can run a hybrid framework that maximizes the
-scalability by trading off between efficiency and convergence rate.
-
-SINGA comes with a programming model designed based on the layer abstraction, which
-is intuitive for deep learning models. A variety of
-popular deep learning models can be expressed and trained using this programming model.
-
-System overview
----------------
-
-.. figure:: /image/sgd.png
-
- Figure 1 - SGD flow
-
-Training a deep learning model is to find the optimal parameters involved in
-the transformation functions that generate good features for specific tasks.
-The goodness of a set of parameters is measured by a loss function, e.g.,
-`Cross-Entropy Loss <https://en.wikipedia.org/wiki/Cross_entropy>`_ . Since the
-loss functions are usually non-linear and non-convex, it is difficult to get a
-closed form solution. Typically, people use the stochastic gradient descent
-(SGD) algorithm, which randomly
-initializes the parameters and then iteratively updates them to reduce the loss
-as shown in Figure 1.
-
-.. figure:: /image/overview.png
-
- Figure 2 - SINGA overview
-
-SGD is used in SINGA to train
-parameters of deep learning models. The training workload is distributed over
-worker and server units as shown in Figure 2. In each
-iteration, every worker calls *TrainOneBatch* function to compute
-parameter gradients. *TrainOneBatch* takes a *NeuralNet* object
-representing the neural net, and visits layers of the *NeuralNet* in
-certain order. The resultant gradients are sent to the local stub that
-aggregates the requests and forwards them to corresponding servers for
-updating. Servers reply to workers with the updated parameters for the next
-iteration.
-
-
-Job submission
---------------
-
-To submit a job in SINGA (i.e., training a deep learning model),
-users pass the job configuration to SINGA driver in the
-`main function <programming-guide.html>`_ . The job configuration
-specifies the four major components in Figure 2,
-
- * a `NeuralNet <neural-net.html>`_ describing the neural net structure with the detailed layer setting and their connections;
- * a `TrainOneBatch <train-one-batch.html>`_ algorithm which is tailored for different model categories;
- * an `Updater <updater.html>`_ defining the protocol for updating parameters at the server side;
- * a `Cluster Topology <distributed-training.html>`_ specifying the distributed architecture of workers and servers.
-
-This process is like the job submission in Hadoop, where users configure their
-jobs in the main function to set the mapper, reducer, etc.
-In Hadoop, users can configure their jobs with their own (or built-in) mapper and reducer; in SINGA, users
-can configure their jobs with their own (or built-in) layer, updater, etc.

+# Train CNN over Cifar-10
+
+
+Convolution neural network (CNN) is a type of feed-forward artificial neural
+network widely used for image and video classification. In this example, we
+will train three deep CNN models to do image classification for the CIFAR-10 dataset,
+
+1. [AlexNet](https://code.google.com/p/cuda-convnet/source/browse/trunk/example-layers/layers-18pct.cfg)
+the best validation accuracy (without data augmentation) we achieved was about 82%.
+
+2. [VGGNet](http://torch.ch/blog/2015/07/30/cifar.html), the best validation accuracy (without data augmentation) we achieved was about 89%.
+3. [ResNet](https://github.com/facebook/fb.resnet.torch), the best validation accuracy (without data augmentation) we achieved was about 83%.
+
+
+## Instructions
+
+
+### SINGA installation
+
+Users can compile and install SINGA from source or install the Python version.
+The code can ran on both CPU and GPU. For GPU training, CUDA and CUDNN (V4 or V5)
+are required. Please refer to the installation page for detailed instructions.
+
+
+
+### Training
+
+There are four training programs
+
+1. train.py. The following command would train the VGG model using the python
+version of the Cifar-10 dataset in 'cifar-10-batches-py' folder.
+
+ python train.py vgg cifar-10-batches-py
+
+ To train other models, please replace 'vgg' to 'alexnet' or 'resnet'. By default
+ the training would run on a CudaGPU device, to run it on CppCPU, add an additional
+ argument
+
+ python train.py vgg cifar-10-batches-py --use_cpu
+
+2. alexnet.cc. It trains the AlexNet model using the CPP APIs on a CudaGPU,
+
+ run.sh
+
+3. alexnet-parallel.cc. It trains the AlexNet model using the CPP APIs on two CudaGPU devices.
+The two devices run synchronously to compute the gradients of the mode parameters, which are
+averaged on the host CPU device and then be applied to update the parameters.
+
+ run-parallel.sh
+
+4. vgg-parallel.cc. It train the VGG model using the CPP APIs on two CudaGPU devices similar to alexnet-parallel.cc.
+
+### Prediction
+
+predict.py includes the prediction function
+
+ def predict(net, images, dev, topk=5)
+
+The net is created by loading the previously trained model; Images consist of
+a numpy array of images (one row per image); dev is the training device, e.g.,
+a CudaGPU device or the host CppCPU device; topk labels of each image would be
+returned.
+
+
+

+## How to Contribute Code
+
+_____
+
+### Coding Style
+
+The SINGA codebase follows the [Google C++ Style Guide](http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml).
+
+To check if your code follows the style, you can use the provided cpplint tool:
+
+ $ ./tool/cpplint.py YOUR_FILE
+
+
+### JIRA format
+
+Like other Apache projects, SINGA uses JIRA to track bugs, improvements and
+other high-level discussions (e.g., system design and features). Github pull requests are
+used for implementation discussions, e.g., code review and code merge.
+
+* Provide a descriptive Title.
+* Write a detailed Description. For bug reports, this should ideally include a
+ short reproduction of the problem. For new features, it may include a design
+ document.
+* Set [required fields](https://cwiki.apache.org/confluence/display/SPARK/Contributing+to+Spark#ContributingtoSpark-JIRA)
+
+### Pull Request
+
+The work flow is
+
+* Fork the [SINGA Github repository](https://github.com/apache/incubator-singa) to
+your own Github account.
+
+* Clone your fork, create a new branch (e.g., feature-foo or fixbug-foo),
+ work on it. After finishing your job,
+ [rebase](https://git-scm.com/book/en/v2/Git-Branching-Rebasing) it to the
+ current latest master and push commits to your own Github account (the new
+ branch).
+
+* Open a pull request against the master branch of apache/incubator-singa.
+The PR title should be of the form SINGA-xxxx Title, where
+SINGA-xxxx is the relevant JIRA number, and Title may be the JIRA's title or a
+more specific title describing the PR itself, for example, "SINGA-6 Implement thread-safe singleton". Detailed description can be copied from the JIRA.
+Consider identifying committers or other contributors who have worked on the
+code being changed. Find the file(s) in Github and click "Blame" to see a
+line-by-line annotation of who changed the code last. You can add @username in
+the PR description to ping them immediately.
+Please state that the contribution is your original work and that you license
+the work to the project under the project's open source license. Further commits (e.g., bug fix)
+to your new branch will be added to this pull request automatically by Github.
+
+* Wait for one committer to review the patch. If no conflicts, the committers will merge it with
+the master branch. The merge should a) not use rebase b) disable fast forward merge c) check the
+commit message format and test the code/feature.
+
+* If there are too many small commit messages, you will be told to squash your commits into fewer meaningful
+commits. If your commit message does not follow the format (i.e., SINGA-xxxx), you will be told to
+reword your commit message. Both changes can be done using interactive git rebase. Once you
+get the commits corrected, push them to you own github again. Your pull request
+will be automatically updated. For details, please refer to
+[Rebase Pull Requests](https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request).

+# How to Contribute Documentation
+
+___
+
+
+## Website
+This document gives step-by-step instructions for deploying [Singa website](http://singa.incubator.apache.org).
+
+Singa website is built by [Sphinx](http://www.sphinx-doc.org) 1.4.4 from a source tree stored in git: https://github.com/apache/incubator-singa/tree/master/doc.
+
+To install Sphinx on Ubuntu:
+
+ $ apt-get install python-sphinx
+
+To install the markdown support for Sphinx:
+
+ $ pip install recommonmark
+
+You can build the website by executing the following command from the doc folder:
+
+ $ make html
+
+The procedure for contributing documentation is the same as [contributing code](contribute-code.html).
+
+
+## CPP API
+
+To generate docs, run "doxygen" from the doc folder (Doxygen >= 1.8 recommended)

+#Quickstart - Cifar10 example
+Convolution neural network (CNN) is a type of feed-forward artificial neural network widely used for image classification. In this example, we will use a deep CNN model to do image classification for the [CIFAR10 dataset](http://www.cs.toronto.edu/~kriz/cifar.html).
+
+## Running instructions for CPP version
+Please refer to [Installation](installation.html) page for how to install SINGA. Currently, we CNN requires CUDNN, hence both CUDA and CUDNN should be installed and SINGA should be compiled with CUDA and CUDNN.
+
+The Cifar10 dataset could be downloaded by running
+
+ # switch to cifar10 directory
+ $ cd ../examples/cifar10
+ # download data for CPP version
+ $ python download_data.py bin
+
+'bin' is for downloading binary version of Cifar10 data.
+
+During downloading, you should see the detailed output like
+
+ Downloading CIFAR10 from http://www.cs.toronto.edu/~kriz/cifar-10-binary.tar.gz
+ The tar file does exist. Extracting it now..
+ Finished!
+
+Now you have prepared the data for this Cifar10 example, the final step is to execute the `run.sh` script,
+
+ # in SINGA_ROOT/examples/cifar10/
+ $ ./run.sh
+
+You should see the detailed output as follows: first read the data files in order, show the statistics of training and testing data, then show the details of neural net structure with some parameter information, finally illustrate the performance details during training and validation process. The number of epochs can be specified in `run.sh` file.

+Device
+=======
+
+
+The Device abstract represents any hardware device with memory and compuation units.
+All [Tensor operations](tensor.html) are scheduled by the resident device for execution.
+Tensor memory is also managed by the device's memory manager. Therefore, optimization
+of memory and execution are implemented in the Device class.
+
+Specific devices
+----------------
+Currently, SINGA has three Device implmentations,
+
+1. CudaGPU for an Nvidia GPU card which runs Cuda code
+2. CppCPU for a CPU which runs Cpp code
+3. OpenclGPU for a GPU card which runs OpenCL code
+

+# Neural Net
+
+---
+
+`NeuralNet` in SINGA represents an instance of user's neural net model. As the
+neural net typically consists of a set of layers, `NeuralNet` comprises
+a set of unidirectionally connected [Layer](layer.html)s.
+This page describes how to convert an user's neural net into
+the configuration of `NeuralNet`.
+
+<img src="../_static/images/model-category.png" align="center" width="200px"/>
+<span><strong>Figure 1 - Categorization of popular deep learning models.</strong></span>
+
+## Net structure configuration
+
+Users configure the `NeuralNet` by listing all layers of the neural net and
+specifying each layer's source layer names. Popular deep learning models can be
+categorized as Figure 1. The subsequent sections give details for each
+category.
+
+### Feed-forward models
+
+<div align = "left">
+<img src="../_static/images/mlp-net.png" align="center" width="200px"/>
+<span><strong>Figure 2 - Net structure of a MLP model.</strong></span>
+</div>
+
+Feed-forward models, e.g., CNN and MLP, can easily get configured as their layer
+connections are undirected without circles. The
+configuration for the MLP model shown in Figure 1 is as follows,
+
+ net {
+ layer {
+ name : 'data"
+ type : kData
+ }
+ layer {
+ name : 'image"
+ type : kImage
+ srclayer: 'data'
+ }
+ layer {
+ name : 'label"
+ type : kLabel
+ srclayer: 'data'
+ }
+ layer {
+ name : 'hidden"
+ type : kHidden
+ srclayer: 'image'
+ }
+ layer {
+ name : 'softmax"
+ type : kSoftmaxLoss
+ srclayer: 'hidden'
+ srclayer: 'label'
+ }
+ }
+
+### Energy models
+
+<img src="../_static/images/rbm-rnn.png" align="center" width="500px"/>
+<span><strong>Figure 3 - Convert connections in RBM and RNN.</strong></span>
+
+
+For energy models including RBM, DBM,
+etc., their connections are undirected (i.e., Category B). To represent these models using
+`NeuralNet`, users can simply replace each connection with two directed
+connections, as shown in Figure 3a. In other words, for each pair of connected layers, their source
+layer field should include each other's name.
+The full [RBM example](rbm.html) has
+detailed neural net configuration for a RBM model, which looks like
+
+ net {
+ layer {
+ name : "vis"
+ type : kVisLayer
+ param {
+ name : "w1"
+ }
+ srclayer: "hid"
+ }
+ layer {
+ name : "hid"
+ type : kHidLayer
+ param {
+ name : "w2"
+ share_from: "w1"
+ }
+ srclayer: "vis"
+ }
+ }
+
+### RNN models
+
+For recurrent neural networks (RNN), users can remove the recurrent connections
+by unrolling the recurrent layer. For example, in Figure 3b, the original
+layer is unrolled into a new layer with 4 internal layers. In this way, the
+model is like a normal feed-forward model, thus can be configured similarly.
+The [RNN example](rnn.html) has a full neural net
+configuration for a RNN model.
+
+
+## Configuration for multiple nets
+
+Typically, a training job includes three neural nets for
+training, validation and test phase respectively. The three neural nets share most
+layers except the data layer, loss layer or output layer, etc.. To avoid
+redundant configurations for the shared layers, users can uses the `exclude`
+filed to filter a layer in the neural net, e.g., the following layer will be
+filtered when creating the testing `NeuralNet`.
+
+
+ layer {
+ ...
+ exclude : kTest # filter this layer for creating test net
+ }
+
+
+
+## Neural net partitioning
+
+A neural net can be partitioned in different ways to distribute the training
+over multiple workers.
+
+### Batch and feature dimension
+
+<img src="../_static/images/partition_fc.png" align="center" width="400px"/>
+<span><strong>Figure 4 - Partitioning of a fully connected layer.</strong></span>
+
+
+Every layer's feature blob is considered a matrix whose rows are feature
+vectors. Thus, one layer can be split on two dimensions. Partitioning on
+dimension 0 (also called batch dimension) slices the feature matrix by rows.
+For instance, if the mini-batch size is 256 and the layer is partitioned into 2
+sub-layers, each sub-layer would have 128 feature vectors in its feature blob.
+Partitioning on this dimension has no effect on the parameters, as every
+[Param](param.html) object is replicated in the sub-layers. Partitioning on dimension
+1 (also called feature dimension) slices the feature matrix by columns. For
+example, suppose the original feature vector has 50 units, after partitioning
+into 2 sub-layers, each sub-layer would have 25 units. This partitioning may
+result in [Param](param.html) object being split, as shown in
+Figure 4. Both the bias vector and weight matrix are
+partitioned into two sub-layers.
+
+
+### Partitioning configuration
+
+There are 4 partitioning schemes, whose configurations are give below,
+
+ 1. Partitioning each singe layer into sub-layers on batch dimension (see
+ below). It is enabled by configuring the partition dimension of the layer to
+ 0, e.g.,
+
+ # with other fields omitted
+ layer {
+ partition_dim: 0
+ }
+
+ 2. Partitioning each singe layer into sub-layers on feature dimension (see
+ below). It is enabled by configuring the partition dimension of the layer to
+ 1, e.g.,
+
+ # with other fields omitted
+ layer {
+ partition_dim: 1
+ }
+
+ 3. Partitioning all layers into different subsets. It is enabled by
+ configuring the location ID of a layer, e.g.,
+
+ # with other fields omitted
+ layer {
+ location: 1
+ }
+ layer {
+ location: 0
+ }
+
+
+ 4. Hybrid partitioning of strategy 1, 2 and 3. The hybrid partitioning is
+ useful for large models. An example application is to implement the
+ [idea proposed by Alex](http://arxiv.org/abs/1404.5997).
+ Hybrid partitioning is configured like,
+
+ # with other fields omitted
+ layer {
+ location: 1
+ }
+ layer {
+ location: 0
+ }
+ layer {
+ partition_dim: 0
+ location: 0
+ }
+ layer {
+ partition_dim: 1
+ location: 0
+ }
+
+Currently SINGA supports strategy-2 well. Other partitioning strategies are
+are under test and will be released in later version.
+
+## Parameter sharing
+
+Parameters can be shared in two cases,
+
+ * sharing parameters among layers via user configuration. For example, the
+ visible layer and hidden layer of a RBM shares the weight matrix, which is configured through
+ the `share_from` field as shown in the above RBM configuration. The
+ configurations must be the same (except name) for shared parameters.
+
+ * due to neural net partitioning, some `Param` objects are replicated into
+ different workers, e.g., partitioning one layer on batch dimension. These
+ workers share parameter values. SINGA controls this kind of parameter
+ sharing automatically, users do not need to do any configuration.
+
+ * the `NeuralNet` for training and testing (and validation) share most layers
+ , thus share `Param` values.
+
+If the shared `Param` instances resident in the same process (may in different
+threads), they use the same chunk of memory space for their values. But they
+would have different memory spaces for their gradients. In fact, their
+gradients will be averaged by the stub or server.
+
+## Advanced user guide
+
+### Creation
+
+ static NeuralNet* NeuralNet::Create(const NetProto& np, Phase phase, int num);
+
+The above function creates a `NeuralNet` for a given phase, and returns a
+pointer to the `NeuralNet` instance. The phase is in {kTrain,
+kValidation, kTest}. `num` is used for net partitioning which indicates the
+number of partitions. Typically, a training job includes three neural nets for
+training, validation and test phase respectively. The three neural nets share most
+layers except the data layer, loss layer or output layer, etc.. The `Create`
+function takes in the full net configuration including layers for training,
+validation and test. It removes layers for phases other than the specified
+phase based on the `exclude` field in
+[layer configuration](layer.html):
+
+ layer {
+ ...
+ exclude : kTest # filter this layer for creating test net
+ }
+
+The filtered net configuration is passed to the constructor of `NeuralNet`:
+
+ NeuralNet::NeuralNet(NetProto netproto, int npartitions);
+
+The constructor creates a graph representing the net structure firstly in
+
+ Graph* NeuralNet::CreateGraph(const NetProto& netproto, int npartitions);
+
+Next, it creates a layer for each node and connects layers if their nodes are
+connected.
+
+ void NeuralNet::CreateNetFromGraph(Graph* graph, int npartitions);
+
+Since the `NeuralNet` instance may be shared among multiple workers, the
+`Create` function returns a pointer to the `NeuralNet` instance .
+
+### Parameter sharing
+
+ `Param` sharing
+is enabled by first sharing the Param configuration (in `NeuralNet::Create`)
+to create two similar (e.g., the same shape) Param objects, and then calling
+(in `NeuralNet::CreateNetFromGraph`),
+
+ void Param::ShareFrom(const Param& from);
+
+It is also possible to share `Param`s of two nets, e.g., sharing parameters of
+the training net and the test net,
+
+ void NeuralNet:ShareParamsFrom(NeuralNet* other);
+
+It will call `Param::ShareFrom` for each Param object.
+
+### Access functions
+`NeuralNet` provides a couple of access function to get the layers and params
+of the net:
+
+ const std::vector<Layer*>& layers() const;
+ const std::vector<Param*>& params() const ;
+ Layer* name2layer(string name) const;
+ Param* paramid2param(int id) const;
+
+
+### Partitioning
+
+
+#### Implementation
+
+SINGA partitions the neural net in `CreateGraph` function, which creates one
+node for each (partitioned) layer. For example, if one layer's partition
+dimension is 0 or 1, then it creates `npartition` nodes for it; if the
+partition dimension is -1, a single node is created, i.e., no partitioning.
+Each node is assigned a partition (or location) ID. If the original layer is
+configured with a location ID, then the ID is assigned to each newly created node.
+These nodes are connected according to the connections of the original layers.
+Some connection layers will be added automatically.
+For instance, if two connected sub-layers are located at two
+different workers, then a pair of bridge layers is inserted to transfer the
+feature (and gradient) blob between them. When two layers are partitioned on
+different dimensions, a concatenation layer which concatenates feature rows (or
+columns) and a slice layer which slices feature rows (or columns) would be
+inserted. These connection layers help making the network communication and
+synchronization transparent to the users.
+
+#### Dispatching partitions to workers
+
+Each (partitioned) layer is assigned a location ID, based on which it is dispatched to one
+worker. Particularly, the pointer to the `NeuralNet` instance is passed
+to every worker within the same group, but each worker only computes over the
+layers that have the same partition (or location) ID as the worker's ID. When
+every worker computes the gradients of the entire model parameters
+(strategy-2), we refer to this process as data parallelism. When different
+workers compute the gradients of different parameters (strategy-3 or
+strategy-1), we call this process model parallelism. The hybrid partitioning
+leads to hybrid parallelism where some workers compute the gradients of the
+same subset of model parameters while other workers compute on different model
+parameters. For example, to implement the hybrid parallelism in for the
+[DCNN model](http://arxiv.org/abs/1404.5997), we set `partition_dim = 0` for
+lower layers and `partition_dim = 1` for higher layers.

+Introduction
+==============
+
+
+SINGA is a general distributed deep learning platform for training big deep
+learning models over large datasets. It is designed with an intuitive
+programming model based on the layer abstraction. A variety
+of popular deep learning models are supported, namely feed-forward models including
+convolutional neural networks (CNN), energy models like restricted Boltzmann
+machine (RBM), and recurrent neural networks (RNN). Many built-in layers are
+provided for users. SINGA architecture is
+sufficiently flexible to run synchronous, asynchronous and hybrid training
+frameworks. SINGA
+also supports different neural net partitioning schemes to parallelize the
+training of large models, namely partitioning on batch dimension, feature
+dimension or hybrid partitioning.
+
+
+Goals
+-----
+
+As a distributed system, the first goal of SINGA is to have good scalability. In other
+words, SINGA is expected to reduce the total training time to achieve certain
+accuracy with more computing resources (i.e., machines).
+
+
+The second goal is to make SINGA easy to use.
+It is non-trivial for programmers to develop and train models with deep and
+complex model structures. Distributed training further increases the burden of
+programmers, e.g., data and model partitioning, and network communication. Hence it is essential to
+provide an easy to use programming model so that users can implement their deep
+learning models/algorithms without much awareness of the underlying distributed
+platform.
+
+Principles
+----------
+
+Scalability is a challenging research problem for distributed deep learning
+training. SINGA provides a general architecture to exploit the scalability of
+different training frameworks. Synchronous training frameworks improve the
+efficiency of one training iteration, and
+asynchronous training frameworks improve the convergence rate. Given a fixed budget
+(e.g., cluster size), users can run a hybrid framework that maximizes the
+scalability by trading off between efficiency and convergence rate.
+
+SINGA comes with a programming model designed based on the layer abstraction, which
+is intuitive for deep learning models. A variety of
+popular deep learning models can be expressed and trained using this programming model.
+
+System overview
+---------------
+
+.. figure:: /image/sgd.png
+
+ Figure 1 - SGD flow
+
+Training a deep learning model is to find the optimal parameters involved in
+the transformation functions that generate good features for specific tasks.
+The goodness of a set of parameters is measured by a loss function, e.g.,
+`Cross-Entropy Loss <https://en.wikipedia.org/wiki/Cross_entropy>`_ . Since the
+loss functions are usually non-linear and non-convex, it is difficult to get a
+closed form solution. Typically, people use the stochastic gradient descent
+(SGD) algorithm, which randomly
+initializes the parameters and then iteratively updates them to reduce the loss
+as shown in Figure 1.
+
+.. figure:: /image/overview.png
+
+ Figure 2 - SINGA overview
+
+SGD is used in SINGA to train
+parameters of deep learning models. The training workload is distributed over
+worker and server units as shown in Figure 2. In each
+iteration, every worker calls *TrainOneBatch* function to compute
+parameter gradients. *TrainOneBatch* takes a *NeuralNet* object
+representing the neural net, and visits layers of the *NeuralNet* in
+certain order. The resultant gradients are sent to the local stub that
+aggregates the requests and forwards them to corresponding servers for
+updating. Servers reply to workers with the updated parameters for the next
+iteration.
+
+
+Job submission
+--------------
+
+To submit a job in SINGA (i.e., training a deep learning model),
+users pass the job configuration to SINGA driver in the
+`main function <programming-guide.html>`_ . The job configuration
+specifies the four major components in Figure 2,
+
+ * a `NeuralNet <neural-net.html>`_ describing the neural net structure with the detailed layer setting and their connections;
+ * a `TrainOneBatch <train-one-batch.html>`_ algorithm which is tailored for different model categories;
+ * an `Updater <updater.html>`_ defining the protocol for updating parameters at the server side;
+ * a `Cluster Topology <distributed-training.html>`_ specifying the distributed architecture of workers and servers.
+
+This process is like the job submission in Hadoop, where users configure their
+jobs in the main function to set the mapper, reducer, etc.
+In Hadoop, users can configure their jobs with their own (or built-in) mapper and reducer; in SINGA, users
+can configure their jobs with their own (or built-in) layer, updater, etc.

+# Software Stack
+
+SINGA's software stack includes three major components, namely, core, IO and
+model. Figure 1 illustrates these components together with the hardware.
+The core component provides memory management and tensor operations;
+IO has classes for reading (and writing) data from (to) disk and network; The
+model component provides data structures and algorithms for machine learning models,
+e.g., layers for neural network models, optimizers/initializer/metric/loss for
+general machine learning models.

+
+## Core
+
+[Tensor](tensor.html) and [Device](device.html) are two core abstractions in SINGA. Tensor class represents a
+multi-dimensional array, which stores model variables and provides linear algebra
+operations for machine learning
+algorithms, including matrix multiplication and random functions. Each tensor
+instance (i.e. a tensor) is allocated on a Device instance.
+Each Device instance (i.e. a device) is created against one hardware device,
+e.g. a GPU card or a CPU core. Devices manage the memory of tensors and execute
+tensor operations on its execution units, e.g. CPU threads or CUDA streams.
+
+Depending on the hardware and the programming language, SINGA have implemented
+the following specific device classes:
+
+* **CudaGPU** represents an Nvidia GPU card. The execution units are the CUDA streams.
+* **CppCPU** represents a normal CPU. The execution units are the CPU threads.
+* **OpenclGPU** represents normal GPU card from both Nvidia and AMD.
+ The execution units are the CommandQueues. Given that OpenCL is compatible with
+ many hardware devices, e.g. FPGA and ARM, the OpenclGPU has the potential to be
+ extended for other devices.
+
+Different types of devices use different programming languages to write the kernel
+functions for tensor operations,
+
+* CppMath (tensor_math_cpp.h) implements the tensor operations using Cpp for CppCPU
+* CudaMath (tensor_math_cuda.h) implements the tensor operations using CUDA for CudaGPU
+* OpenclMath (tensor_math_opencl.h) implements the tensor operations using OpenCL for OpenclGPU
+
+In addition, different types of data, such as float32 and float16, could be supported by adding
+the corresponding tensor functions.
+
+Typically, users would create a device instance and pass it to create multiple
+tensor instances. When users call the Tensor functions, these function would invoke
+the corresponding implementation (CppMath/CudaMath/OpenclMath) automatically. In
+other words, the implementation of Tensor operations is transparent to users.
+
+Most machine learning algorithms could be expressed using (dense or sparse) tensors.
+Therefore, with the Tensor abstraction, SINGA would be able to run a wide range of models,
+including deep learning models and other traditional machine learning models.
+
+The Tensor and Device abstractions are extensible to support a wide range of hardware device
+using different programming languages. A new hardware device would be supported by
+adding a new Device subclass and the corresponding implementation of the Tensor
+operations (xxxMath).
+
+Optimizations in terms of speed and memory could be implemented by Device, which
+manages both operation execution and memory malloc/free. More optimization details
+would be described in the [Device page](device.html).
+
+
+## Model
+
+On top of the Tensor and Device abstractions, SINGA provides some higher level
+classes for machine learning modules.
+
+* [Layer](layer.html) and its subclasses are specific for neural networks. Every layer provides
+ functions for forward propagating features and backward propagating gradients w.r.t the training loss functions.
+ They wraps the complex layer operations so that users can easily create neural nets
+ by connecting a set of layers.
+
+* [Initializer](initializer.html) and its subclasses provide variant methods of initializing
+ model parameters (stored in Tensor instances), following Uniform, Gaussian, etc.
+
+* [Loss](loss.html) and its subclasses defines the training objective loss functions.
+ Both functions of computing the loss values and computing the gradient of the prediction w.r.t the
+ objective loss are implemented. Example loss functions include squared error and cross entropy.
+
+* [Metric](metric.html) and its subclasses provide the function to measure the
+ performance of the model, e.g., the accuracy.
+
+* [Optimizer](optimizer.html) and its subclasses implement the methods for updating
+ model parameter values using parameter gradients, including SGD, AdaGrad, RMSProp etc.
+
+
+## IO
+
+The IO module consists of classes for data loading, data preprocessing and message passing.
+
+* Reader and its subclasses load string records from disk files
+* Writer and its subclasses write string records to disk files
+* Encoder and its subclasses encode Tensor instances into string records
+* Decoder and its subclasses decodes string records into Tensor instances
+* Endpoint represents a communication endpoint which provides functions for passing messages to each other.
+* Message represents communication messages between Endpoint instances. It carries both meta data and payload.

+Tensor
+========
+
+Each Tensor instance is a multi-dimensional array allocated on a specific
+Device instance. Tensor instances store variables and provide
+linear algebra operations over different types of hardware devices without user
+awareness. Note that users need to make sure the tensor operands are
+allocated on the same device except copy functions.
+
+
+Tensor implementation
+---------------------
+
+SINGA has three different sets of implmentations of Tensor functions, one for each
+type of Device.
+
+* 'tensor_math_cpp.h' implements operations using Cpp (with CBLAS) for CppGPU devices.
+* 'tensor_math_cuda.h' implements operations using Cuda (with cuBLAS) for CudaGPU devices.
+* 'tensor_math_opencl.h' implements operations using OpenCL for OpenclGPU devices.
+
+Python API
+----------
+
+There are two set of tensor functions,
+1. Tensor member functions, which would change the internal state of the Tensor instance.
+2. tensor module functions, which accepts Tensor instances as arguments and return
+Tensor instances.
+
+
+Create Tensor instances
+~~~~~~~~~~~~~~~~~~~~~~~
+
+.. autoclass:: singa.tensor.Tensor
+
+
+Tensor instances can be constructed from Numpy array,
+
+.. automodule:: singa.tensor
+ :members: from_numpy
+
+
+Set Tensor values

+Tensor
+========
+
+Each Tensor instance is a multi-dimensional array allocated on a specific
+Device instance. Tensor instances store variables and provide
+linear algebra operations over different types of hardware devices without user
+awareness. Note that users need to make sure the tensor operands are
+allocated on the same device except copy functions.
+
+
+Tensor implementation
+---------------------
+
+SINGA has three different sets of implmentations of Tensor functions, one for each
+type of Device.
+
+* 'tensor_math_cpp.h' implements operations using Cpp (with CBLAS) for CppGPU devices.
+* 'tensor_math_cuda.h' implements operations using Cuda (with cuBLAS) for CudaGPU devices.
+* 'tensor_math_opencl.h' implements operations using OpenCL for OpenclGPU devices.

-===========
+-----------
Apache SINGA is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

documentation files for SINGA v1.0
Posted by wa...@apache.org.
SINGA-237 New documentation files for SINGA v1.0
Update the layer identifier to be consistent with the documentation.
In particualr, the identifier prefix should be one of
['cudnn','singacpp', 'singacuda', 'singacl']. The complete identifier
would be <prefix>_xxxx, e.g., cudnn_convolution and
singacpp_convolution. The identifier should not have upper case letters.
If the implmentation is transparent to cpp/cuda/opencl, then register all
possible identifiers. For instance, Dropout is registered three times,
RegisterLayerClass("singacpp_dropout", Dropout)
RegisterLayerClass("singacl_dropout", Dropout)
RegisterLayerClass("singacuda_dropout", Dropout)

+"""Does google-lint on c++ files.
+
+The goal of this script is to identify places in the code that *may*
+be in non-compliance with google style. It does not attempt to fix
+up these problems -- the point is to educate. It does also not
+attempt to find all problems, or to ensure that everything it does
+find is legitimately a problem.
+
+In particular, we can get very confused by /* and // inside strings!
+We do a small hack, which is to ignore //'s with "'s after them on the
+same line, but it is far from perfect (in either direction).

+# Software Stack
+
+SINGA's software stack includes three major components, namely, core, IO and
+model. Figure 1 illustrates these components together with the hardware.
+The core component provides memory management and tensor operations;
+IO has classes for reading (and writing) data from (to) disk and network; The
+model component provides data structures and algorithms for machine learning models,
+e.g., layers for neural network models, optimizers/initializer/metric/loss for
+general machine learning models.
+
+
+<img src="../_static/images/singav1-sw.png" align="center" width="500px"/>
+<br/>
+<span><strong>Figure 1 - SINGA V1 software stack.</strong></span>
+
+## Core
+
+[Tensor](tensor.html) and [Device](device.html) are two core abstractions in SINGA. Tensor class represents a
+multi-dimensional array, which stores model variables and provides linear algebra
+operations for machine learning
+algorithms, including matrix multiplication and random functions. Each tensor
+instance (i.e. a tensor) is allocated on a Device instance.
+Each Device instance (i.e. a device) is created against one hardware device,
+e.g. a GPU card or a CPU core. Devices manage the memory of tensors and execute
+tensor operations on its execution units, e.g. CPU threads or CUDA streams.
+
+Depending on the hardware and the programming language, SINGA have implemented
+the following specific device classes:
+
+* **CudaGPU** represents an Nvidia GPU card. The execution units are the CUDA streams.
+* **CppCPU** represents a normal CPU. The execution units are the CPU threads.
+* **OpenclGPU** represents normal GPU card from both Nvidia and AMD.
+ The execution units are the CommandQueues. Given that OpenCL is compatible with
+ many hardware devices, e.g. FPGA and ARM, the OpenclGPU has the potential to be
+ extended for other devices.
+
+Different types of devices use different programming languages to write the kernel
+functions for tensor operations,
+
+* CppMath (tensor_math_cpp.h) implements the tensor operations using Cpp for CppCPU
+* CudaMath (tensor_math_cuda.h) implements the tensor operations using CUDA for CudaGPU
+* OpenclMath (tensor_math_opencl.h) implements the tensor operations using OpenCL for OpenclGPU
+
+In addition, different types of data, such as float32 and float16, could be supported by adding
+the corresponding tensor functions.
+
+Typically, users would create a device instance and pass it to create multiple
+tensor instances. When users call the Tensor functions, these function would invoke
+the corresponding implementation (CppMath/CudaMath/OpenclMath) automatically. In
+other words, the implementation of Tensor operations is transparent to users.
+
+Most machine learning algorithms could be expressed using (dense or sparse) tensors.
+Therefore, with the Tensor abstraction, SINGA would be able to run a wide range of models,
+including deep learning models and other traditional machine learning models.
+
+The Tensor and Device abstractions are extensible to support a wide range of hardware device
+using different programming languages. A new hardware device would be supported by
+adding a new Device subclass and the corresponding implementation of the Tensor
+operations (xxxMath).
+
+Optimizations in terms of speed and memory could be implemented by Device, which
+manages both operation execution and memory malloc/free. More optimization details
+would be described in the [Device page](device.html).
+
+
+## Model
+
+On top of the Tensor and Device abstractions, SINGA provides some higher level
+classes for machine learning modules.
+
+* [Layer](layer.html) and its subclasses are specific for neural networks. Every layer provides
+ functions for forward propagating features and backward propagating gradients w.r.t the training loss functions.
+ They wraps the complex layer operations so that users can easily create neural nets
+ by connecting a set of layers.
+
+* [Initializer](initializer.html) and its subclasses provide variant methods of initializing
+ model parameters (stored in Tensor instances), following Uniform, Gaussian, etc.
+
+* [Loss](loss.html) and its subclasses defines the training objective loss functions.
+ Both functions of computing the loss values and computing the gradient of the prediction w.r.t the
+ objective loss are implemented. Example loss functions include squared error and cross entropy.
+
+* [Metric](metric.html) and its subclasses provide the function to measure the
+ performance of the model, e.g., the accuracy.
+
+* [Optimizer](optimizer.html) and its subclasses implement the methods for updating
+ model parameter values using parameter gradients, including SGD, AdaGrad, RMSProp etc.
+
+
+## IO
+
+The IO module consists of classes for data loading, data preprocessing and message passing.
+
+* Reader and its subclasses load string records from disk files
+* Writer and its subclasses write string records to disk files
+* Encoder and its subclasses encode Tensor instances into string records
+* Decoder and its subclasses decodes string records into Tensor instances
+* Endpoint represents a communication endpoint which provides functions for passing messages to each other.
+* Message represents communication messages between Endpoint instances. It carries both meta data and payload.

++
++Then, run the following command
++
++ $ sudo pip install --upgrade $SINGA_WHEEL_URL
++
++If you do not have sudo right, you can run `pip install` in a python virtual environment.
++
++
++### From source
++
++Please compile SINGA from source (see the next section) with the 'USE_PYTHON' option on,
++and then run the following commands,
++
++ # under the build directory
++ $ cd python
++ $ sudo pip install .
++
++If you are using a virtual environment, you can ignore the `sudo` keyword.
++
++Developers can build the wheel file via
++
++ # under the build directory
++ $ cd python
++ $ python setup.py bdist_wheel
++
++
++The generated wheel file is under "dist" directory
++
++
++## Build SINGA from source
++
++Please clone the newest code from [Github](https://github.com/apache/incubator-singa) and execute the following commands,
++
++ $ git clone https://github.com/apache/incubator-singa.git
++ $ cd incubator-singa/
++
++If you use CUDA, then [CNMeM](https://github.com/NVIDIA/cnmem) is necessary,
++which could be downloaded as
++
++ $ git submodule init
++ $ git submodule update
++
++
++### Linux & MacOS
++
++GCC (>=4.8.1) is required to compile SINGA on Linux.
++For Mac OS users, you can use either GCC or Clang.
++
++In SINGA_ROOT, execute the following commands for compiling SINGA,
++
++ $ mkdir build && cd build
++ $ cmake ..
++ $ make
++ $ make install
++
++Note that if you are using CUDNN and it is not installed under system default
++folder, you need to let cmake know the paths to CUDNN,
++
++ $ export CMAKE_INCLUDE_PATH=<path to cudnn>/include:$CMAKE_INCLUDE_PATH
++ $ export CMAKE_LIBRARY_PATH=<path to cudnn>/lib64:$CMAKE_LIBRARY_PATH
++
++You can use `ccmake ..` to configure the compilation options including using
++generating python binding and changing the installation folder.
++If the dependent libraries are not in the system default paths, you need to export
++the following environment variables
++
++ export CMAKE_INCLUDE_PATH=<path to your header file folder>
++ export CMAKE_LIBRARY_PATH=<path to your lib file folder>
++
++After compiling SINGA, you can run the unit tests by
++
++ $ ./bin/test_singa
++
++You can see all the testing cases with testing results. If SINGA passes all
++tests, then you have successfully installed SINGA. Please proceed to try the examples!
++
++
++### Windows
++To be added.
++
++
++## FAQ
++
++* Q: Error from running `cmake ..`, which cannot find the dependent libraries.
++
++ A: If you haven't installed the libraries, please install them. If you installed
++ the libraries in a folder that is outside of the system folder, e.g. /usr/local,
++ please export the following variables
++
++ export CMAKE_INCLUDE_PATH=<path to your header file folder>
++ export CMAKE_LIBRARY_PATH=<path to your lib file folder>
++
++
++* Q: Error from `make`, e.g. the linking phase
++
++ A: If your libraries are in other folders than system default paths, you need
++ to export the following varaibles
++
++ $ export LIBRARY_PATH=<path to your lib file folder>
++ $ export LD_LIBRARY_PATH=<path to your lib file folder>
++
++
++* Q: Error from header files, e.g. 'cblas.h no such file or directory exists'
++
++ A: You need to include the folder of the cblas.h into CPLUS_INCLUDE_PATH,
++ e.g.,
++
++ $ export CPLUS_INCLUDE_PATH=/opt/OpenBLAS/include:$CPLUS_INCLUDE_PATH
++
++* Q:While compiling SINGA, I get error `SSE2 instruction set not enabled`
++
++ A:You can try following command:
++
++ $ make CFLAGS='-msse2' CXXFLAGS='-msse2'
++
++* Q:I get `ImportError: cannot import name enum_type_wrapper` from google.protobuf.internal when I try to import .py files.
++
++ A: You need to install the python binding of protobuf, which could be installed via
++
++ $ sudo apt-get install protobuf
++
++ or from source
++
++ $ cd /PROTOBUF/SOURCE/FOLDER
++ $ cd python
++ $ python setup.py build
++ $ python setup.py install
++
++* Q: When I build OpenBLAS from source, I am told that I need a Fortran compiler.
++
++ A: You can compile OpenBLAS by
++
++ $ make ONLY_CBLAS=1
++
++ or install it using
++
++ $ sudo apt-get install libopenblas-dev
++
++* Q: When I build protocol buffer, it reports that GLIBC++_3.4.20 not found in /usr/lib64/libstdc++.so.6.
++
++ A9: This means the linker found libstdc++.so.6 but that library
++ belongs to an older version of GCC than was used to compile and link the
++ program. The program depends on code defined in
++ the newer libstdc++ that belongs to the newer version of GCC, so the linker
++ must be told how to find the newer libstdc++ shared library.
++ The simplest way to fix this is to find the correct libstdc++ and export it to
++ LD_LIBRARY_PATH. For example, if GLIBC++_3.4.20 is listed in the output of the
++ following command,
++
++ $ strings /usr/local/lib64/libstdc++.so.6|grep GLIBC++
++
++ then you just set your environment variable as
++
++ $ export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
++
++* Q: When I build glog, it reports that "src/logging_unittest.cc:83:20: error: \u2018gflags\u2019 is not a namespace-name"
++
++ A: It maybe that you have installed gflags with a different namespace such as "google". so glog can't find 'gflags' namespace.
++ Because it is not necessary to have gflags to build glog. So you can change the configure.ac file to ignore gflags.
++
++ 1. cd to glog src directory
++ 2. change line 125 of configure.ac to "AC_CHECK_LIB(gflags, main, ac_cv_have_libgflags=0, ac_cv_have_libgflags=0)"
++ 3. autoreconf
++
++ After this, you can build glog again.

SINGA-217 build python package with setup.py
- Singa python binding, package with pip or create wheel
- In the cmake file, specify USE_PYTHON ON, then cmake and make.
After that run "<sudo> pip install ." under "build/python" path
User can run command 'singa' in a model workspace to serve and train
- dependent on numpy>=1.11.0; protobuf>=2.5.0,<3; flask>=0.10.1
Users should also install openblas
- Models are sharing on github gists.
- Todo, optimize cmake compile method to avoid compile source file twice
refine singa command

+Tensor
+========
+
+Each Tensor instance is a multi-dimensional array allocated on a specific
+Device instance. Tensor instances store variables and provide
+linear algebra operations over different types of hardware devices without user
+awareness. Note that users need to make sure the tensor operands are
+allocated on the same device except copy functions.
+
+
+Tensor implementation
+---------------------
+
+SINGA has three different sets of implmentations of Tensor functions, one for each
+type of Device.
+
+* 'tensor_math_cpp.h' implements operations using Cpp (with CBLAS) for CppGPU devices.
+* 'tensor_math_cuda.h' implements operations using Cuda (with cuBLAS) for CudaGPU devices.

-===========
+-----------
Apache SINGA is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

[38/51] [abbrv] incubator-singa git commit: fix minor bug
Posted by wa...@apache.org.
fix minor bug
1. in pool.cc due to buf check, which should be done only for average pooling
2. update the tensor.py to avoid error in to_numpy() due to
inconsistency of swig tensor and py tensor members, e.g. device/shape.

Fixed the bug leading to wired accuracy (nan), which was caused by forgeting
to average the gradient over the whole mini-batch. That is why we need a lower
learning rate and could not use momentum.
Update the lr in optimzier.py to time the multiplier
Fix the bug from mis-setting the pooling type of alexnet.py (max-->avg)

+# Software Stack
+
+SINGA's software stack includes three major components, namely, core, IO and
+model. Figure 1 illustrates these components together with the hardware.
+The core component provides memory management and tensor operations;
+IO has classes for reading (and writing) data from (to) disk and network; The
+model component provides data structures and algorithms for machine learning models,
+e.g., layers for neural network models, optimizers/initializer/metric/loss for
+general machine learning models.
+
+
+<img src="../_static/images/singav1-sw.png" align="center" width="500px"/>
+<br/>
+<span><strong>Figure 1 - SINGA V1 software stack.</strong></span>
+
+## Core
+
+[Tensor](tensor.html) and [Device](device.html) are two core abstractions in SINGA. Tensor class represents a
+multi-dimensional array, which stores model variables and provides linear algebra
+operations for machine learning
+algorithms, including matrix multiplication and random functions. Each tensor
+instance (i.e. a tensor) is allocated on a Device instance.
+Each Device instance (i.e. a device) is created against one hardware device,
+e.g. a GPU card or a CPU core. Devices manage the memory of tensors and execute
+tensor operations on its execution units, e.g. CPU threads or CUDA streams.
+
+Depending on the hardware and the programming language, SINGA have implemented
+the following specific device classes:
+
+* **CudaGPU** represents an Nvidia GPU card. The execution units are the CUDA streams.
+* **CppCPU** represents a normal CPU. The execution units are the CPU threads.
+* **OpenclGPU** represents normal GPU card from both Nvidia and AMD.
+ The execution units are the CommandQueues. Given that OpenCL is compatible with
+ many hardware devices, e.g. FPGA and ARM, the OpenclGPU has the potential to be
+ extended for other devices.
+
+Different types of devices use different programming languages to write the kernel
+functions for tensor operations,
+
+* CppMath (tensor_math_cpp.h) implements the tensor operations using Cpp for CppCPU
+* CudaMath (tensor_math_cuda.h) implements the tensor operations using CUDA for CudaGPU
+* OpenclMath (tensor_math_opencl.h) implements the tensor operations using OpenCL for OpenclGPU
+
+In addition, different types of data, such as float32 and float16, could be supported by adding
+the corresponding tensor functions.
+
+Typically, users would create a device instance and pass it to create multiple
+tensor instances. When users call the Tensor functions, these function would invoke
+the corresponding implementation (CppMath/CudaMath/OpenclMath) automatically. In
+other words, the implementation of Tensor operations is transparent to users.
+
+Most machine learning algorithms could be expressed using (dense or sparse) tensors.
+Therefore, with the Tensor abstraction, SINGA would be able to run a wide range of models,
+including deep learning models and other traditional machine learning models.
+
+The Tensor and Device abstractions are extensible to support a wide range of hardware device
+using different programming languages. A new hardware device would be supported by
+adding a new Device subclass and the corresponding implementation of the Tensor
+operations (xxxMath).
+
+Optimizations in terms of speed and memory could be implemented by Device, which
+manages both operation execution and memory malloc/free. More optimization details
+would be described in the [Device page](device.html).
+
+
+## Model
+
+On top of the Tensor and Device abstractions, SINGA provides some higher level
+classes for machine learning modules.
+
+* [Layer](layer.html) and its subclasses are specific for neural networks. Every layer provides
+ functions for forward propagating features and backward propagating gradients w.r.t the training loss functions.
+ They wraps the complex layer operations so that users can easily create neural nets
+ by connecting a set of layers.
+
+* [Initializer](initializer.html) and its subclasses provide variant methods of initializing
+ model parameters (stored in Tensor instances), following Uniform, Gaussian, etc.
+
+* [Loss](loss.html) and its subclasses defines the training objective loss functions.
+ Both functions of computing the loss values and computing the gradient of the prediction w.r.t the
+ objective loss are implemented. Example loss functions include squared error and cross entropy.
+
+* [Metric](metric.html) and its subclasses provide the function to measure the
+ performance of the model, e.g., the accuracy.
+
+* [Optimizer](optimizer.html) and its subclasses implement the methods for updating
+ model parameter values using parameter gradients, including SGD, AdaGrad, RMSProp etc.
+
+
+## IO
+
+The IO module consists of classes for data loading, data preprocessing and message passing.
+
+* Reader and its subclasses load string records from disk files
+* Writer and its subclasses write string records to disk files
+* Encoder and its subclasses encode Tensor instances into string records
+* Decoder and its subclasses decodes string records into Tensor instances
+* Endpoint represents a communication endpoint which provides functions for passing messages to each other.
+* Message represents communication messages between Endpoint instances. It carries both meta data and payload.

[06/51] [abbrv] incubator-singa git commit: SINGA-217 build python
package with setup.py
Posted by wa...@apache.org.
SINGA-217 build python package with setup.py
CudnnRNN requires cudnn version later than 5.05, the previous check
based on CUDNN_VERSION_MAJOR and CUDNN_VERSION_PATCH does not work for
version 5.13. Therefore, we replaced the check to CUDNN_VERSION >= 5005.
CUDNN_VERSION is defined in cudnn.h.
cmake defines CUDNN_VERSION_SWIG which is used by model_layer.i for cudnn
rnn.
Remvoe the hardcoded sys imports for python files. Now users need to
install the python module to run python examples and tests.
Tested installation in python virtual enviornment and conda
virtural enviorment:
Inside build/python
```
pip install -e .
```

+# Install SINGA Python Module
+
+SINGA provide a python binding for python programers. Users can either install from source or
+from pre-built wheel file.
+
+## Install from source
+
+### Required
+* python(==2.7)
+* pip(>=1.5)
+* SWIG(>=3.0)
+* numpy(>=1.11.0)
+* Google protobuf(>=2.5,<3)
+
+
+### Configuration
+To build SINGA python package, users should turn on python building switch in cmake config file: "CMakeList.txt"
+
+ OPTION(USE_PYTHON "Generate py wrappers" ON)
+
+### Instructions
+Follow the instructions in the above sections to build SINGA from source,
+
+After that, execute the following commands:
+
+ # under the build directory
+ $ cd python
+ $ sudo pip install .
+
+Then singa package should be installed in the corresponding python library.
+
+## Pip Install from wheel
+
+Install pip if it is not already installed:
+
+ $ sudo apt-get install python-pip python-dev
+
+Then, select the correct binary to install:
+
+ # Ubuntu/Linux 64-bit, CPU only, Python 2.7, Protobuf 2.5
+ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.5/singa-1.0.0-cp27-none-linux_x86_64.whl
+
+ # Ubuntu/Linux 64-bit, CPU only, Python 2.7, Protobuf 2.6
+ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.6/singa-1.0.0-cp27-none-linux_x86_64.whl
+
+ # Ubuntu/Linux 64-bit, GPU enabled, Python 2.7, Protobuf 2.5, CUDA toolkit 7.5 and CuDNN v5
+ $ export SINGA_WHEEL_URL=http://comp.nus.edu.sg/~dbsystem/singa/assets/file/pb2.5-cuda7.5-cudnn5/singa-1.0.0-cp27-none-linux_x86_64.whl

+
+Install SINGA:
+
+ $ sudo pip install --upgrade $SINGA_WHEEL_URL
+
+### build wheel file from source
+
+Users can build wheel file from source. After build SINGA, execute the following commands:
+
+ # under the build directory
+ $ cd python
+ $ python setup.py bdist_wheel
+
+Then users may get built wheel file under "dist" directory

-## How to Contribute Code
-
-_____
-
-### Coding Style
-
-The SINGA codebase follows the [Google C++ Style Guide](http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml).
-
-To check if your code follows the style, you can use the provided cpplint tool:
-
- $ ./tool/cpplint.py YOUR_FILE
-
-
-### JIRA format
-
-Like other Apache projects, SINGA uses JIRA to track bugs, improvements and
-other high-level discussions (e.g., system design and features). Github pull requests are
-used for implementation discussions, e.g., code review and code merge.
-
-* Provide a descriptive Title.
-* Write a detailed Description. For bug reports, this should ideally include a
- short reproduction of the problem. For new features, it may include a design
- document.
-* Set [required fields](https://cwiki.apache.org/confluence/display/SPARK/Contributing+to+Spark#ContributingtoSpark-JIRA)
-
-### Pull Request
-
-The work flow is
-
-* Fork the [SINGA Github repository](https://github.com/apache/incubator-singa) to
-your own Github account.
-
-* Clone your fork, create a new branch (e.g., feature-foo or fixbug-foo),
- work on it. After finishing your job,
- [rebase](https://git-scm.com/book/en/v2/Git-Branching-Rebasing) it to the
- current latest master and push commits to your own Github account (the new
- branch).
-
-* Open a pull request against the master branch of apache/incubator-singa.
-The PR title should be of the form SINGA-xxxx Title, where
-SINGA-xxxx is the relevant JIRA number, and Title may be the JIRA's title or a
-more specific title describing the PR itself, for example, "SINGA-6 Implement thread-safe singleton". Detailed description can be copied from the JIRA.
-Consider identifying committers or other contributors who have worked on the
-code being changed. Find the file(s) in Github and click "Blame" to see a
-line-by-line annotation of who changed the code last. You can add @username in
-the PR description to ping them immediately.
-Please state that the contribution is your original work and that you license
-the work to the project under the project's open source license. Further commits (e.g., bug fix)
-to your new branch will be added to this pull request automatically by Github.
-
-* Wait for one committer to review the patch. If no conflicts, the committers will merge it with
-the master branch. The merge should a) not use rebase b) disable fast forward merge c) check the
-commit message format and test the code/feature.
-
-* If there are too many small commit messages, you will be told to squash your commits into fewer meaningful
-commits. If your commit message does not follow the format (i.e., SINGA-xxxx), you will be told to
-reword your commit message. Both changes can be done using interactive git rebase. Once you
-get the commits corrected, push them to you own github again. Your pull request
-will be automatically updated. For details, please refer to
-[Rebase Pull Requests](https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request).

-# How to Contribute Documentation
-
-___
-
-
-## Website
-This document gives step-by-step instructions for deploying [Singa website](http://singa.incubator.apache.org).
-
-Singa website is built by [Sphinx](http://www.sphinx-doc.org) 1.4.4 from a source tree stored in git: https://github.com/apache/incubator-singa/tree/master/doc.
-
-To install Sphinx on Ubuntu:
-
- $ apt-get install python-sphinx
-
-To install the markdown support for Sphinx:
-
- $ pip install recommonmark
-
-You can build the website by executing the following command from the doc folder:
-
- $ make html
-
-The procedure for contributing documentation is the same as [contributing code](contribute-code.html).

-#Quickstart - Cifar10 example
-Convolution neural network (CNN) is a type of feed-forward artificial neural network widely used for image classification. In this example, we will use a deep CNN model to do image classification for the [CIFAR10 dataset](http://www.cs.toronto.edu/~kriz/cifar.html).
-
-## Running instructions for CPP version
-Please refer to [Installation](installation.html) page for how to install SINGA. Currently, we CNN requires CUDNN, hence both CUDA and CUDNN should be installed and SINGA should be compiled with CUDA and CUDNN.
-
-The Cifar10 dataset could be downloaded by running
-
- # switch to cifar10 directory
- $ cd ../examples/cifar10
- # download data for CPP version
- $ python download_data.py bin
-
-'bin' is for downloading binary version of Cifar10 data.
-
-During downloading, you should see the detailed output like
-
- Downloading CIFAR10 from http://www.cs.toronto.edu/~kriz/cifar-10-binary.tar.gz
- The tar file does exist. Extracting it now..
- Finished!
-
-Now you have prepared the data for this Cifar10 example, the final step is to execute the `run.sh` script,
-
- # in SINGA_ROOT/examples/cifar10/
- $ ./run.sh
-
-You should see the detailed output as follows: first read the data files in order, show the statistics of training and testing data, then show the details of neural net structure with some parameter information, finally illustrate the performance details during training and validation process. The number of epochs can be specified in `run.sh` file.

-
-## Running instructions for Python version
-To run CNN example in Python version, we need to compile SINGA with Python binding,
-
- $ mkdir build && cd build
- $ cmake -DUSE_PYTHON=ON ..
- $ make
-
-Now download the Cifar10 dataset,
-
- # switch to cifar10 directory
- $ cd ../examples/cifar10
- # download data for Python version
- $ python download_data.py py
-
-During downloading, you should see the detailed output like
-
- Downloading CIFAR10 from http://www.cs.toronto.edu/~kriz/cifar-10-python.tar.gz
- The tar file does exist. Extracting it now..
- Finished!
-
-Then execute the `train.py` script to build the model
-
- $ python train.py
-
-You should see the output as follows including the details of neural net structure with some parameter information, reading data files, and the performance details during training and testing process.

-Device
-=======
-
-
-The Device abstract represents any hardware device with memory and compuation units.
-All [Tensor operations](tensor.html) are scheduled by the resident device for execution.
-Tensor memory is also managed by the device's memory manager. Therefore, optimization
-of memory and execution are implemented in the Device class.
-
-Specific devices
-----------------
-Currently, SINGA has three Device implmentations,
-
-1. CudaGPU for an Nvidia GPU card which runs Cuda code
-2. CppCPU for a CPU which runs Cpp code
-3. OpenclGPU for a GPU card which runs OpenCL code

-# Neural Net
-
----
-
-`NeuralNet` in SINGA represents an instance of user's neural net model. As the
-neural net typically consists of a set of layers, `NeuralNet` comprises
-a set of unidirectionally connected [Layer](layer.html)s.
-This page describes how to convert an user's neural net into
-the configuration of `NeuralNet`.
-
-<img src="../_static/images/model-category.png" align="center" width="200px"/>
-<span><strong>Figure 1 - Categorization of popular deep learning models.</strong></span>
-
-## Net structure configuration
-
-Users configure the `NeuralNet` by listing all layers of the neural net and
-specifying each layer's source layer names. Popular deep learning models can be
-categorized as Figure 1. The subsequent sections give details for each
-category.
-
-### Feed-forward models
-
-<div align = "left">
-<img src="../_static/images/mlp-net.png" align="center" width="200px"/>
-<span><strong>Figure 2 - Net structure of a MLP model.</strong></span>
-</div>
-
-Feed-forward models, e.g., CNN and MLP, can easily get configured as their layer
-connections are undirected without circles. The
-configuration for the MLP model shown in Figure 1 is as follows,
-
- net {
- layer {
- name : 'data"
- type : kData
- }
- layer {
- name : 'image"
- type : kImage
- srclayer: 'data'
- }
- layer {
- name : 'label"
- type : kLabel
- srclayer: 'data'
- }
- layer {
- name : 'hidden"
- type : kHidden
- srclayer: 'image'
- }
- layer {
- name : 'softmax"
- type : kSoftmaxLoss
- srclayer: 'hidden'
- srclayer: 'label'
- }
- }
-
-### Energy models
-
-<img src="../_static/images/rbm-rnn.png" align="center" width="500px"/>
-<span><strong>Figure 3 - Convert connections in RBM and RNN.</strong></span>
-
-
-For energy models including RBM, DBM,
-etc., their connections are undirected (i.e., Category B). To represent these models using
-`NeuralNet`, users can simply replace each connection with two directed
-connections, as shown in Figure 3a. In other words, for each pair of connected layers, their source
-layer field should include each other's name.
-The full [RBM example](rbm.html) has
-detailed neural net configuration for a RBM model, which looks like
-
- net {
- layer {
- name : "vis"
- type : kVisLayer
- param {
- name : "w1"
- }
- srclayer: "hid"
- }
- layer {
- name : "hid"
- type : kHidLayer
- param {
- name : "w2"
- share_from: "w1"
- }
- srclayer: "vis"
- }
- }
-
-### RNN models
-
-For recurrent neural networks (RNN), users can remove the recurrent connections
-by unrolling the recurrent layer. For example, in Figure 3b, the original
-layer is unrolled into a new layer with 4 internal layers. In this way, the
-model is like a normal feed-forward model, thus can be configured similarly.
-The [RNN example](rnn.html) has a full neural net
-configuration for a RNN model.
-
-
-## Configuration for multiple nets
-
-Typically, a training job includes three neural nets for
-training, validation and test phase respectively. The three neural nets share most
-layers except the data layer, loss layer or output layer, etc.. To avoid
-redundant configurations for the shared layers, users can uses the `exclude`
-filed to filter a layer in the neural net, e.g., the following layer will be
-filtered when creating the testing `NeuralNet`.
-
-
- layer {
- ...
- exclude : kTest # filter this layer for creating test net
- }
-
-
-
-## Neural net partitioning
-
-A neural net can be partitioned in different ways to distribute the training
-over multiple workers.
-
-### Batch and feature dimension
-
-<img src="../_static/images/partition_fc.png" align="center" width="400px"/>
-<span><strong>Figure 4 - Partitioning of a fully connected layer.</strong></span>
-
-
-Every layer's feature blob is considered a matrix whose rows are feature
-vectors. Thus, one layer can be split on two dimensions. Partitioning on
-dimension 0 (also called batch dimension) slices the feature matrix by rows.
-For instance, if the mini-batch size is 256 and the layer is partitioned into 2
-sub-layers, each sub-layer would have 128 feature vectors in its feature blob.
-Partitioning on this dimension has no effect on the parameters, as every
-[Param](param.html) object is replicated in the sub-layers. Partitioning on dimension
-1 (also called feature dimension) slices the feature matrix by columns. For
-example, suppose the original feature vector has 50 units, after partitioning
-into 2 sub-layers, each sub-layer would have 25 units. This partitioning may
-result in [Param](param.html) object being split, as shown in
-Figure 4. Both the bias vector and weight matrix are
-partitioned into two sub-layers.
-
-
-### Partitioning configuration
-
-There are 4 partitioning schemes, whose configurations are give below,
-
- 1. Partitioning each singe layer into sub-layers on batch dimension (see
- below). It is enabled by configuring the partition dimension of the layer to
- 0, e.g.,
-
- # with other fields omitted
- layer {
- partition_dim: 0
- }
-
- 2. Partitioning each singe layer into sub-layers on feature dimension (see
- below). It is enabled by configuring the partition dimension of the layer to
- 1, e.g.,
-
- # with other fields omitted
- layer {
- partition_dim: 1
- }
-
- 3. Partitioning all layers into different subsets. It is enabled by
- configuring the location ID of a layer, e.g.,
-
- # with other fields omitted
- layer {
- location: 1
- }
- layer {
- location: 0
- }
-
-
- 4. Hybrid partitioning of strategy 1, 2 and 3. The hybrid partitioning is
- useful for large models. An example application is to implement the
- [idea proposed by Alex](http://arxiv.org/abs/1404.5997).
- Hybrid partitioning is configured like,
-
- # with other fields omitted
- layer {
- location: 1
- }
- layer {
- location: 0
- }
- layer {
- partition_dim: 0
- location: 0
- }
- layer {
- partition_dim: 1
- location: 0
- }
-
-Currently SINGA supports strategy-2 well. Other partitioning strategies are
-are under test and will be released in later version.
-
-## Parameter sharing
-
-Parameters can be shared in two cases,
-
- * sharing parameters among layers via user configuration. For example, the
- visible layer and hidden layer of a RBM shares the weight matrix, which is configured through
- the `share_from` field as shown in the above RBM configuration. The
- configurations must be the same (except name) for shared parameters.
-
- * due to neural net partitioning, some `Param` objects are replicated into
- different workers, e.g., partitioning one layer on batch dimension. These
- workers share parameter values. SINGA controls this kind of parameter
- sharing automatically, users do not need to do any configuration.
-
- * the `NeuralNet` for training and testing (and validation) share most layers
- , thus share `Param` values.
-
-If the shared `Param` instances resident in the same process (may in different
-threads), they use the same chunk of memory space for their values. But they
-would have different memory spaces for their gradients. In fact, their
-gradients will be averaged by the stub or server.
-
-## Advanced user guide
-
-### Creation
-
- static NeuralNet* NeuralNet::Create(const NetProto& np, Phase phase, int num);
-
-The above function creates a `NeuralNet` for a given phase, and returns a
-pointer to the `NeuralNet` instance. The phase is in {kTrain,
-kValidation, kTest}. `num` is used for net partitioning which indicates the
-number of partitions. Typically, a training job includes three neural nets for
-training, validation and test phase respectively. The three neural nets share most
-layers except the data layer, loss layer or output layer, etc.. The `Create`
-function takes in the full net configuration including layers for training,
-validation and test. It removes layers for phases other than the specified
-phase based on the `exclude` field in
-[layer configuration](layer.html):
-
- layer {
- ...
- exclude : kTest # filter this layer for creating test net
- }
-
-The filtered net configuration is passed to the constructor of `NeuralNet`:
-
- NeuralNet::NeuralNet(NetProto netproto, int npartitions);
-
-The constructor creates a graph representing the net structure firstly in
-
- Graph* NeuralNet::CreateGraph(const NetProto& netproto, int npartitions);
-
-Next, it creates a layer for each node and connects layers if their nodes are
-connected.
-
- void NeuralNet::CreateNetFromGraph(Graph* graph, int npartitions);
-
-Since the `NeuralNet` instance may be shared among multiple workers, the
-`Create` function returns a pointer to the `NeuralNet` instance .
-
-### Parameter sharing
-
- `Param` sharing
-is enabled by first sharing the Param configuration (in `NeuralNet::Create`)
-to create two similar (e.g., the same shape) Param objects, and then calling
-(in `NeuralNet::CreateNetFromGraph`),
-
- void Param::ShareFrom(const Param& from);
-
-It is also possible to share `Param`s of two nets, e.g., sharing parameters of
-the training net and the test net,
-
- void NeuralNet:ShareParamsFrom(NeuralNet* other);
-
-It will call `Param::ShareFrom` for each Param object.
-
-### Access functions
-`NeuralNet` provides a couple of access function to get the layers and params
-of the net:
-
- const std::vector<Layer*>& layers() const;
- const std::vector<Param*>& params() const ;
- Layer* name2layer(string name) const;
- Param* paramid2param(int id) const;
-
-
-### Partitioning
-
-
-#### Implementation
-
-SINGA partitions the neural net in `CreateGraph` function, which creates one
-node for each (partitioned) layer. For example, if one layer's partition
-dimension is 0 or 1, then it creates `npartition` nodes for it; if the
-partition dimension is -1, a single node is created, i.e., no partitioning.
-Each node is assigned a partition (or location) ID. If the original layer is
-configured with a location ID, then the ID is assigned to each newly created node.
-These nodes are connected according to the connections of the original layers.
-Some connection layers will be added automatically.
-For instance, if two connected sub-layers are located at two
-different workers, then a pair of bridge layers is inserted to transfer the
-feature (and gradient) blob between them. When two layers are partitioned on
-different dimensions, a concatenation layer which concatenates feature rows (or
-columns) and a slice layer which slices feature rows (or columns) would be
-inserted. These connection layers help making the network communication and
-synchronization transparent to the users.
-
-#### Dispatching partitions to workers
-
-Each (partitioned) layer is assigned a location ID, based on which it is dispatched to one
-worker. Particularly, the pointer to the `NeuralNet` instance is passed
-to every worker within the same group, but each worker only computes over the
-layers that have the same partition (or location) ID as the worker's ID. When
-every worker computes the gradients of the entire model parameters
-(strategy-2), we refer to this process as data parallelism. When different
-workers compute the gradients of different parameters (strategy-3 or
-strategy-1), we call this process model parallelism. The hybrid partitioning
-leads to hybrid parallelism where some workers compute the gradients of the
-same subset of model parameters while other workers compute on different model
-parameters. For example, to implement the hybrid parallelism in for the
-[DCNN model](http://arxiv.org/abs/1404.5997), we set `partition_dim = 0` for
-lower layers and `partition_dim = 1` for higher layers.

-Introduction
-==============
-
-
-SINGA is a general distributed deep learning platform for training big deep
-learning models over large datasets. It is designed with an intuitive
-programming model based on the layer abstraction. A variety
-of popular deep learning models are supported, namely feed-forward models including
-convolutional neural networks (CNN), energy models like restricted Boltzmann
-machine (RBM), and recurrent neural networks (RNN). Many built-in layers are
-provided for users. SINGA architecture is
-sufficiently flexible to run synchronous, asynchronous and hybrid training
-frameworks. SINGA
-also supports different neural net partitioning schemes to parallelize the
-training of large models, namely partitioning on batch dimension, feature
-dimension or hybrid partitioning.
-
-
-Goals
------
-
-As a distributed system, the first goal of SINGA is to have good scalability. In other
-words, SINGA is expected to reduce the total training time to achieve certain
-accuracy with more computing resources (i.e., machines).
-
-
-The second goal is to make SINGA easy to use.
-It is non-trivial for programmers to develop and train models with deep and
-complex model structures. Distributed training further increases the burden of
-programmers, e.g., data and model partitioning, and network communication. Hence it is essential to
-provide an easy to use programming model so that users can implement their deep
-learning models/algorithms without much awareness of the underlying distributed
-platform.
-
-Principles
-----------
-
-Scalability is a challenging research problem for distributed deep learning
-training. SINGA provides a general architecture to exploit the scalability of
-different training frameworks. Synchronous training frameworks improve the
-efficiency of one training iteration, and
-asynchronous training frameworks improve the convergence rate. Given a fixed budget
-(e.g., cluster size), users can run a hybrid framework that maximizes the
-scalability by trading off between efficiency and convergence rate.
-
-SINGA comes with a programming model designed based on the layer abstraction, which
-is intuitive for deep learning models. A variety of
-popular deep learning models can be expressed and trained using this programming model.
-
-System overview
----------------
-
-.. figure:: /image/sgd.png
-
- Figure 1 - SGD flow
-
-Training a deep learning model is to find the optimal parameters involved in
-the transformation functions that generate good features for specific tasks.
-The goodness of a set of parameters is measured by a loss function, e.g.,
-`Cross-Entropy Loss <https://en.wikipedia.org/wiki/Cross_entropy>`_ . Since the
-loss functions are usually non-linear and non-convex, it is difficult to get a
-closed form solution. Typically, people use the stochastic gradient descent
-(SGD) algorithm, which randomly
-initializes the parameters and then iteratively updates them to reduce the loss
-as shown in Figure 1.
-
-.. figure:: /image/overview.png
-
- Figure 2 - SINGA overview
-
-SGD is used in SINGA to train
-parameters of deep learning models. The training workload is distributed over
-worker and server units as shown in Figure 2. In each
-iteration, every worker calls *TrainOneBatch* function to compute
-parameter gradients. *TrainOneBatch* takes a *NeuralNet* object
-representing the neural net, and visits layers of the *NeuralNet* in
-certain order. The resultant gradients are sent to the local stub that
-aggregates the requests and forwards them to corresponding servers for
-updating. Servers reply to workers with the updated parameters for the next
-iteration.
-
-
-Job submission
---------------
-
-To submit a job in SINGA (i.e., training a deep learning model),
-users pass the job configuration to SINGA driver in the
-`main function <programming-guide.html>`_ . The job configuration
-specifies the four major components in Figure 2,
-
- * a `NeuralNet <neural-net.html>`_ describing the neural net structure with the detailed layer setting and their connections;
- * a `TrainOneBatch <train-one-batch.html>`_ algorithm which is tailored for different model categories;
- * an `Updater <updater.html>`_ defining the protocol for updating parameters at the server side;
- * a `Cluster Topology <distributed-training.html>`_ specifying the distributed architecture of workers and servers.
-
-This process is like the job submission in Hadoop, where users configure their
-jobs in the main function to set the mapper, reducer, etc.
-In Hadoop, users can configure their jobs with their own (or built-in) mapper and reducer; in SINGA, users
-can configure their jobs with their own (or built-in) layer, updater, etc.

-# Software Stack
-
-SINGA's software stack includes three major components, namely, core, IO and
-model. Figure 1 illustrates these components together with the hardware.
-The core component provides memory management and tensor operations;
-IO has classes for reading (and writing) data from (to) disk and network; The
-model component provides data structures and algorithms for machine learning models,
-e.g., layers for neural network models, optimizers/initializer/metric/loss for
-general machine learning models.

-<br/>
-<span><strong>Figure 1 - SINGA V1 software stack.</strong></span>
-
-## Core
-
-[Tensor](tensor.html) and [Device](device.html) are two core abstractions in SINGA. Tensor class represents a
-multi-dimensional array, which stores model variables and provides linear algebra
-operations for machine learning
-algorithms, including matrix multiplication and random functions. Each tensor
-instance (i.e. a tensor) is allocated on a Device instance.
-Each Device instance (i.e. a device) is created against one hardware device,
-e.g. a GPU card or a CPU core. Devices manage the memory of tensors and execute
-tensor operations on its execution units, e.g. CPU threads or CUDA streams.
-
-Depending on the hardware and the programming language, SINGA have implemented
-the following specific device classes:
-
-* **CudaGPU** represents an Nvidia GPU card. The execution units are the CUDA streams.
-* **CppCPU** represents a normal CPU. The execution units are the CPU threads.
-* **OpenclGPU** represents normal GPU card from both Nvidia and AMD.
- The execution units are the CommandQueues. Given that OpenCL is compatible with
- many hardware devices, e.g. FPGA and ARM, the OpenclGPU has the potential to be
- extended for other devices.
-
-Different types of devices use different programming languages to write the kernel
-functions for tensor operations,
-
-* CppMath (tensor_math_cpp.h) implements the tensor operations using Cpp for CppCPU
-* CudaMath (tensor_math_cuda.h) implements the tensor operations using CUDA for CudaGPU
-* OpenclMath (tensor_math_opencl.h) implements the tensor operations using OpenCL for OpenclGPU
-
-In addition, different types of data, such as float32 and float16, could be supported by adding
-the corresponding tensor functions.
-
-Typically, users would create a device instance and pass it to create multiple
-tensor instances. When users call the Tensor functions, these function would invoke
-the corresponding implementation (CppMath/CudaMath/OpenclMath) automatically. In
-other words, the implementation of Tensor operations is transparent to users.
-
-Most machine learning algorithms could be expressed using (dense or sparse) tensors.
-Therefore, with the Tensor abstraction, SINGA would be able to run a wide range of models,
-including deep learning models and other traditional machine learning models.
-
-The Tensor and Device abstractions are extensible to support a wide range of hardware device
-using different programming languages. A new hardware device would be supported by
-adding a new Device subclass and the corresponding implementation of the Tensor
-operations (xxxMath).
-
-Optimizations in terms of speed and memory could be implemented by Device, which
-manages both operation execution and memory malloc/free. More optimization details
-would be described in the [Device page](device.html).
-
-
-## Model
-
-On top of the Tensor and Device abstractions, SINGA provides some higher level
-classes for machine learning modules.
-
-* [Layer](layer.html) and its subclasses are specific for neural networks. Every layer provides
- functions for forward propagating features and backward propagating gradients w.r.t the training loss functions.
- They wraps the complex layer operations so that users can easily create neural nets
- by connecting a set of layers.
-
-* [Initializer](initializer.html) and its subclasses provide variant methods of initializing
- model parameters (stored in Tensor instances), following Uniform, Gaussian, etc.
-
-* [Loss](loss.html) and its subclasses defines the training objective loss functions.
- Both functions of computing the loss values and computing the gradient of the prediction w.r.t the
- objective loss are implemented. Example loss functions include squared error and cross entropy.
-
-* [Metric](metric.html) and its subclasses provide the function to measure the
- performance of the model, e.g., the accuracy.
-
-* [Optimizer](optimizer.html) and its subclasses implement the methods for updating
- model parameter values using parameter gradients, including SGD, AdaGrad, RMSProp etc.
-
-
-## IO
-
-The IO module consists of classes for data loading, data preprocessing and message passing.
-
-* Reader and its subclasses load string records from disk files
-* Writer and its subclasses write string records to disk files
-* Encoder and its subclasses encode Tensor instances into string records
-* Decoder and its subclasses decodes string records into Tensor instances
-* Endpoint represents a communication endpoint which provides functions for passing messages to each other.
-* Message represents communication messages between Endpoint instances. It carries both meta data and payload.

-Tensor
-========
-
-Each Tensor instance is a multi-dimensional array allocated on a specific
-Device instance. Tensor instances store variables and provide
-linear algebra operations over different types of hardware devices without user
-awareness. Note that users need to make sure the tensor operands are
-allocated on the same device except copy functions.
-
-
-Tensor implementation
----------------------
-
-SINGA has three different sets of implmentations of Tensor functions, one for each
-type of Device.
-
-* 'tensor_math_cpp.h' implements operations using Cpp (with CBLAS) for CppGPU devices.
-* 'tensor_math_cuda.h' implements operations using Cuda (with cuBLAS) for CudaGPU devices.
-* 'tensor_math_opencl.h' implements operations using OpenCL for OpenclGPU devices.
-
-Python API
-----------
-
-There are two set of tensor functions,
-1. Tensor member functions, which would change the internal state of the Tensor instance.
-2. tensor module functions, which accepts Tensor instances as arguments and return
-Tensor instances.
-
-
-Create Tensor instances
-~~~~~~~~~~~~~~~~~~~~~~~
-
-.. autoclass:: singa.tensor.Tensor
-
-
-Tensor instances can be constructed from Numpy array,
-
-.. automodule:: singa.tensor
- :members: from_numpy
-
-
-Set Tensor values
-~~~~~~~~~~~~~~~~~

-**Disclaimer**
-
-Apache SINGA is an effort undergoing incubation at The Apache Software
-Foundation (ASF), sponsored by the name of Apache Incubator PMC. Incubation is
-required of all newly accepted projects until a further review indicates that
-the infrastructure, communications, and decision making process have stabilized
-in a manner consistent with other successful ASF projects. While incubation
-status is not necessarily a reflection of the completeness or stability of the
-code, it does indicate that the project has yet to be fully endorsed by the
-ASF.

[02/51] [abbrv] incubator-singa git commit: SINGA-235 - Unify the
engines for cudnn and singa layers
Posted by wa...@apache.org.
SINGA-235 - Unify the engines for cudnn and singa layers
For most layers, we would have multiple implementations, e.g., using
cudnn for nvidia gpu, using cpp for cpu and using opencl for other gpus.
These layers have different classes. They are registered with different
identifiers. This ticket would unify the layer identifiers for each
engine:
1. cudnn layers are registered with identifier = cudnn_xxx, e.g.,
cudnn_convolution for the CudnnConvolution layer.
2. singa layers are registered with identifier = singa_xxx, e.g.,
singa_convolution for the Convolution layer.
cudnn engine must run on cuda devices. and singa engine could run on
cuda-gpu device or cpp-cpu device depending on the layer type. For
instance, the Convolution layer must run on cpp-cpu device, and Dense
layer can run on both devices and would select the correct device
automatically.
Users need to make sure the engine and the device of the tensors.
Both CPP and Python code is updated. Users have to compose the layer
identifier manually for CPP version. For Python version, users can set
layer.engine='cudnn' or 'singa'.
All identifiers are case insensitive.
