Subject [jira] [Commented] (DRILL-2039) use forks-per-CPU units in forkCount
Date Thu, 09 Apr 2015 18:53:13 GMT

Hanifi Gunes commented on DRILL-2039:
-------------------------------------

We have tried on multiple machines with 1C option. It does not seem to cause timeouts except
I/O intensive tests(TestWriteToDisk etc) whose timeout intervals are individually lifted up.

> Can Surefire's fork count be set using units of forks per CPU instead of the absolute
number of forks (i.e., {{<forkCount>1C</forkCount>}} instead of {{<forkCount>4</forkcount>}})?
> That would let developers with more powerful machines still run tests in parallel while
letting others avoid or reduce test timeout errors without the risk of forgetting to re-edit
pom.xml after every switch to a different git branch.
