[SYSTEMDS-2686] Compressed overlapping column groups This commit change the compressed right multiplication to perform in compressed space, resulting in significantly faster execution. The technique employed results in overlapping column groups, that contain partial results of the matrix multiplication. The downside is that some operations that previously was possible on compressed space no longer works, for the overlapping column groups. To still support all the operations, then decompression is used for cases where it is impossible to execute on the compressed matrices. Another addition is that statistics now contain compression and decompression times if compression is enabled. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
