[jira] [Updated] (SYSTEMML-585) JMLC disable all multi-threaded
operations
[ https://issues.apache.org/jira/browse/SYSTEMML-585?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Matthias Boehm updated SYSTEMML-585:
------------------------------------
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.
