Subject [jira] [Commented] (SYSTEMML-2389) Forget to fetch the last iteration in local workers
Date Tue, 12 Jun 2018 21:33:00 GMT

    [ https://issues.apache.org/jira/browse/SYSTEMML-2389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16510234#comment-16510234

LI Guobao commented on SYSTEMML-2389:
-------------------------------------

[~mboehm7], in fact, with respect to the runtime error _ArrayIndexOutOfBounds -1_, I still
not understand the reason for that. Could explain it with some detail? I appreciate that.
And then I found another problem concerning the calculation of batch iteration number for
workers. I have fixed it already. But afterwards, the test will fail due to the runtime array
error. Because the size of last iteration will often be small. In this case, I think we need
to fix this problem before doing the PR for this ticket.

> Currently, in local workers, the last iteration of mini batch is ignored because of a
problem when calculating the number of iteration which is a double value.
