Subject [jira] [Commented] (LUCENE-5212) java 7u40 causes sigsegv and corrupt term vectors
Date Sat, 14 Sep 2013 07:54:52 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-5212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13767407#comment-13767407

Dawid Weiss commented on LUCENE-5212:
-------------------------------------

> (sorry, dynamicAssignmentRatio=0 doesnt quite work),

The lack of determinism may be due to work stealing -- dynamicAssignmentRatio=0 preallocates
tasks to JVMs, while work stealing *may* actually assign differently on every run.

Perhaps we should run jenkins jobs with dynamicAssignmentRatio=0... but then all the benefits
of work time balancing among cores would be gone and fixed task assignment only helps in very
specific bug cases (inter-suite dependency or JVM bugs). Hard to tell.
