Subject [jira] [Commented] (IGNITE-7097) performance measurement for SparseDistributedMatrix multiplication
Date Wed, 06 Dec 2017 16:28:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-7097?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16280426#comment-16280426

Oleg Ignatenko commented on IGNITE-7097:

I experimented with running benchmarks using ML codebase in master: the issue is still reproducible.
Whatever causes it, apparently hasn't been fixed yet. Plan to check if maybe there is some
kind of leak, maybe intermediate objects are created by {{likeMatrix}} or {{likeVector}} somewhere
within multiplication without corresponding {{destroy}} because in past experiments it was
missing destroy that caused yardstick to hang

> We want to start tracking our performance to avoid performance degradation. Also we need
some performance comparison with other ml libs.
> Initial draft for this benchmark was made per IGNITE-6123 (class {{IgniteSparseDistributedMatrixMulBenchmark}})
but it currently hangs so it is excluded. Find a way to do it right.
