Matthias Boehm commented on SYSTEMML-2157: ------------------------------------------ The issue showed up on {{algorithms/autoencoder.dml}} over a scaled mnist1m dataset, where the codegen optimizer was about 25% slower than the codegen heuristics. Now with the fix, the codegen optimizer is as expected faster than the heuristics. Also, I should really do a better job closing finished JIRAs as this was addressed by https://github.com/apache/systemml/commit/14ea51be70ede04dfd3d351205b5ab19f1109d91. > Codegen optimizer row to cell conversion destroys fusion plans > -------------------------------------------------------------- > > Key: SYSTEMML-2157 > URL: https://issues.apache.org/jira/browse/SYSTEMML-2157 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Janardhan > Priority: Major > Fix For: SystemML 1.1 > > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
