Baunsgaard opened a new pull request #1197:
URL: https://github.com/apache/systemds/pull/1197


   This commit modifies the code our MMChain operation in CLA to use the
   matrix operations rather than the vector operations. furthermore if found
   to be prudent the mmchain will now no longer decompress.
   
   The right Matrix Multiplication is changed to include a decompression
   from compressed overlapping, since the decompression operation is more
   optimized than the decompression internal to the right matrix multiplication.
   This also gives a clearer view of where we are using our time in the
   statistics output of the execution.
   
   The modifications made LmCG go from ~250 to ~90 sec
   while ULA is at 200sec (unlike the paper this is with num cols iterations)
