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.
