-----------------------------------------------------------------
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}} (possibly eg through {{copy}})
somewhere within multiplication without corresponding {{destroy}} because in
past experiments it was missing destroy that caused yardstick to hang

> Key: IGNITE-7097
> URL: https://issues.apache.org/jira/browse/IGNITE-7097
> Project: Ignite
> Issue Type: Task
> Components: ml, yardstick
> Reporter: Oleg Ignatenko
> Assignee: Oleg Ignatenko
> Fix For: 2.4
>
>
> 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.
