[systemds] 01/03: [SYSTEMDS-2610] CLA updates
Posted by ba...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
baunsgaard pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/systemds.git
commit 67bb8034611a766ca93c0314ee735a3252e79290
Author: baunsgaard <ba...@tugraz.at>
AuthorDate: Mon Aug 30 16:28:31 2021 +0200
[SYSTEMDS-2610] CLA updates
- Compressed matrix factory improvements
- Add decompression if the data is serialized and larger in compressed format
- Decompress on write to HDFS
- Abort compression after cocode if the compression sizes are bad
- Make c bind decompressing in workload tree (worst case)
- Add a minimum compression ratio argument to the CompressionSettings
- Reduce the sampling size in c bind compression and set high minimum compression ratio
- Fix order of operations in compressed append
- Add compressed output size to unary hops
- More utilization of the cached decompressed matrix if it fits in
memory by looking for soft reference of uncompressed in certain cases

[systemds] 03/03: [SYSTEMDS-2990] Workload tree move decompression
to input hop
Posted by ba...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
baunsgaard pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/systemds.git
commit 61f40bd6af0291c2340974d3a2e1074181a51822
Author: baunsgaard <ba...@tugraz.at>
AuthorDate: Wed Sep 8 17:04:04 2021 +0200
[SYSTEMDS-2990] Workload tree move decompression to input hop
This commit move the decompression instruction to the input hop
of a decompressing instruction execution on the workload trees.
this in practice means that if a variable is used in a forloop
and needs decompression it is taken into account that the decompression
only happens once, and outside the for loop.
- Update to allow return of constant column groups in various cases
- Remove System.out.println from estim estimatorDensityMap
- Add Compression in loop right mult with decompression
- Fix Binary matrix matrix operation Compressed
- Add isDensifying boolean to compression cost, to allow compression
to compare to dense allocation.
- add missing minus on empty operator
Closes #1385

[systemds] 02/03: [SYSTEMDS-3123] Rewrite c bind 0 Matrix
Multiplication
Posted by ba...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
baunsgaard pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/systemds.git
commit e607544ea6ab1f2ec1c9f2c8370c38c86c346170
Author: baunsgaard <ba...@tugraz.at>
AuthorDate: Tue Sep 7 19:14:56 2021 +0200
[SYSTEMDS-3123] Rewrite c bind 0 Matrix Multiplication
```
cbind((X %*% Y), matrix(0, nrow(X), 1))
->
X %*% (cbind(Y, matrix(0, nrow(Y), 1)))
```
This commit contains a rewrite that change the sequences if number
of rows in X is 2x larger than Y:
This rewrite effects MLogReg in line 215 to not force allocation of the
large X twice.
