[GitHub] [systemds] phaniarnab opened a new pull request #1471: [SYSTEMDS-3236] Cache-friendly Apply phase for dense target matrix
phaniarnab opened a new pull request #1471:
URL: https://github.com/apache/systemds/pull/1471
This patch adds loop-tiling logic to the apply phase of transformencode
to exploit CPU caches. Currently, the changes are limited to dense
matrices.
Loop-tiling shows 2x performance improvement in recoding a frame
having 5M rows, 100 columens (100K unique in each) and w/ 32 threads.
