[GitHub] [systemds] Shafaq-Siddiqi opened a new pull request, #1581: [SYSTEMDS-3347] Flatten the nested loop for parallel pipelines execution
Shafaq-Siddiqi opened a new pull request, #1581:
URL: https://github.com/apache/systemds/pull/1581
- This commit flattens the nested parfor loop in run_with_hyperparam()
to increase the degress of parallelism by materializing the pipelines and
resource hyper-parameters together in one frame and then execute them in a single parfor
instead of parfor over pipelines and then nesting for hyper-parameters
- This commit also introduce a frame builtin freplicate() that takes two parameters
one multi-row frame and one single row frame and replicate the single row frame to multi-row.
