             Summary: Optional dynamic recompilation for JMLC training
                 Key: SYSTEMML-1750
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1750
             Project: SystemML
          Issue Type: Task
            Reporter: Matthias Boehm


There are scenarios where JMLC is used for training on moderately sized input. Due to the use of prepared scripts (which are compiled without size information) and forced singlenode execution type, this can lead to performance problems caused by poor plan choices. This task aims to (1) expose compiler configurations such as dynamic recompilation and multi-threading at JMLC API and (2) rework the recompilation framework for singlenode execution type.
