> 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.
