Summary: More aggressive dynamic recompilation w/ codegen
Key: SYSTEMML-1904
URL: https://issues.apache.org/jira/browse/SYSTEMML-1904
Project: SystemML
Issue Type: Sub-task
Reporter: Matthias Boehm
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.
