[jira] [Commented] (SYSTEMML-2482) Unexpected cleanup of list object

["Matthias Boehm (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SYSTEMML-2482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16567381#comment-16567381 ] 

Matthias Boehm commented on SYSTEMML-2482:
------------------------------------------

Could you please be more specific what issue you encountered and how it manifests itself as it's important to properly cleanup these lists; otherwise there are unnecessary evictions in the general case. In any case, we might need to adapt the cleanup logic in paramserv accordingly.

> Some unexpected overhead occurred when running the {{*testParamservASPEpochDisjointContiguous*}} in test {{*org.apache.sysml.test.integration.functions.paramserv.ParamservSparkNNTest*}}. It took more time to finish the test in the case that the output of instruction is a list which will be cleaned up after the execution. However, the matrices referenced by the list should be pinned to avoid being cleaned up. And this issue is related to [SYSTEMML-2481|https://issues.apache.org/jira/browse/SYSTEMML-2481]
