Matthias Boehm resolved SYSTEMML-1459. -------------------------------------- Resolution: Fixed Assignee: Matthias Boehm Fix Version/s: SystemML 1.0 > Wrong codegen materialization decisions due to dangling hop parents > ------------------------------------------------------------------- > > Key: SYSTEMML-1459 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1459 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Fix For: SystemML 1.0 > > > The cost-based codegen plan selector uses hops with multiple consumers as > candidates for decisions on materalization points. On end-to-end algorithm > scenarios, we encountered side effects from specific dynamic simplification > rewrites which did not properly cleanup parent-child pointers of removed hops. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
