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.
