> 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.
