Aditya Kishore commented on DRILL-2039:
---------------------------------------
It is causing trouble on my MacBook with 16 logical cores and 16GB of RAM. Half
of the forked tests are killed immediately by OS for lack of memory.
> use forks-per-CPU units in forkCount

> Project: Apache Drill
> Issue Type: Improvement
> Components: Tools, Build & Test
> Reporter: Daniel Barclay (Drill)

> Priority: Minor

> 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.
