Matthias Boehm closed SYSTEMML-1984. ------------------------------------ Resolution: Fixed Assignee: Matthias Boehm Fix Version/s: SystemML 1.0 > Robustness JMLC wrt non-thread-local prepare and execute > -------------------------------------------------------- > > Key: SYSTEMML-1984 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1984 > Project: SystemML > Issue Type: Task > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Priority: Blocker > Fix For: SystemML 1.0 > > > The JMLC API has an underlying assumption that prepared scripts are created > and executed by the same thread because compiler configurations and output > variable names for dynamic recompilation are maintained with thread-local > variables. However, in complex scoring pipelines this is not the case leading > to performance issues (e.g., multi-threaded operations despite > single-threaded configuration) and in the worst case lost result variables. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
