Glenn Weidner updated SYSTEMML-1861: ------------------------------------ Fix Version/s: (was: SystemML 1.0) SystemML 0.15 > Performance sparse-sparse binary ops > ------------------------------------ > > Key: SYSTEMML-1861 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1861 > Project: SystemML > Issue Type: Task > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Fix For: SystemML 0.15 > > > This task aims to improve the performance of sparse-sparse binary operations > such as elementwise multiply. Currently, we use a merge join with outer join > semantics to cover the general case - for operations like multiply this is > unnecessary and could be improved by using inner join semantics and > branchless position maintenance. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
