>             Fix For: SystemML 1.0
> 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.
