Matthias Boehm closed SYSTEMML-1904. ------------------------------------ Resolution: Done Assignee: Matthias Boehm > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
