----------------------------------------
Summary: 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
Priority: Blocker
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.
