[jira] [Updated] (SYSTEMML-1809) Optimize the performance of the
distributed MNIST_LeNet_Sgd model training
[ https://issues.apache.org/jira/browse/SYSTEMML-1809?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Fei Hu updated SYSTEMML-1809:
-----------------------------
Description:
For the current version, the distributed MNIST_LeNet_Sdg model training can be optimized from the following aspects:
# Optimize the DML scripts with considering the backend engine, such as the intermediate matrixes are exported to HDFS, so we need to avoid unnecessary intermediate matrixes.
# Data locality: for {{RemoteParForSpark}}, the tasks are parallelized without considering data locality. It will cause a lot of data shuffling if the volume of the input data size is large;
# Result merge: the current experiments indicate that the result merge part took more time than model training.
After the optimization, we need to compare the performance with the distributed Tensorflow.
