> More aggressive dynamic recompilation w/ codegen
> ------------------------------------------------

> Key: SYSTEMML-1904
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1904
> Project: SystemML
> Issue Type: Sub-task
> Components: Compiler, Runtime
> Reporter: Matthias Boehm
> Assignee: Matthias Boehm
> Fix For: SystemML 1.0
>
>
> This task aims to improve scenarios where we currently disable - despite
> unknown dimensions - dynamic recompilation too eagerly due to good worst-case
> estimates, which hurts performance in case of codegen. This is because the
> cost-based codegen optimizer requires sizes for validity conditions and cost
> estimates.
> Accordingly, if codegen is enabled, we flag operations as requires recompile
> in case of unknown dimensions even if we were able to compile these
> operations to CP.
