Matthias Boehm created SYSTEMML-1544:
----------------------------------------

             Summary: Parfor constrained optimizer dp decision unaware of forced mode
                 Key: SYSTEMML-1544
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1544
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


The constrained parfor optimizer selects the data partitioning strategy without awareness
for forced execution types which can lead to unnecessary out-of-memory errors if the dataset
is partitionable and fits into the driver, a user forces remote execution, and the dataset
does not into the executor tasks.
