Matthias Boehm updated SYSTEMML-584: ------------------------------------ Description: SystemML allows to execute multiple script instances concurrently but only in separate processes. When running multiple instances in a shared process (e.g., for JMLC in-memory scoring), updates of global variables might lead to side effects between script instances. This task aims to resolve any potential issues by a rework of our configuration management towards thread-local custom configurations combined with global read-only configurations. > JMLC thread-local configurations changes > ---------------------------------------- > > Key: SYSTEMML-584 > URL: https://issues.apache.org/jira/browse/SYSTEMML-584 > Project: SystemML > Issue Type: Bug > Components: APIs, comiler, Runtime > Reporter: Matthias Boehm > > SystemML allows to execute multiple script instances concurrently but only in > separate processes.
