Matthias Boehm closed SYSTEMML-2400. ------------------------------------ Resolution: Fixed Assignee: Matthias Boehm Fix Version/s: SystemML 1.2 > Dynamic recompilation loses max thread constraints of hops > ---------------------------------------------------------- > > Key: SYSTEMML-2400 > URL: https://issues.apache.org/jira/browse/SYSTEMML-2400 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Priority: Major > Fix For: SystemML 1.2 > > > Dynamic recompilation deep copies the hop DAG and applies - among other > things - various rewrites. In case these rewrites create new hops (no inplace > modification) these rewrites lose the max thread constraints set by parfor > and paramserv. On nodes with large degree of parallelism this constitutes a > serious issue because it leads to large over-provisioning and thus reduced > performance and potential OOMs. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
