[GitHub] [systemds] Baunsgaard opened a new pull request #1157: [SYSTEMDS-2614] Compressed Right Matrix Multiplication
Baunsgaard opened a new pull request #1157:
URL: https://github.com/apache/systemds/pull/1157
This commit revisits 2614 that introduced compressed right matrix multiplication.
with the minor changes in this commit to correctly use threadLocal
memory, and better blocks for decompression in a right matrix
multiplication the performance (depending on data characteristics and
system) becomes 2-8x faster for the compressed operation, meaning that
if there is co-coding of columns the operation is equal or up to 6x
faster than our default right matrix multiplication.
