Re: [creduce-dev] parallel tuning
Eric I would love to see updated numbers.
But also, I think it's most friendly to provide a good default for the
common case of a single-socket Core-i7, not some quad-socket monster

How does this match with your experience?
I haven't really experimented with this.
I do think, though, that limiting parallelism to 4 is probably not a good
I used to run C-Reduce on Emulab's d820's, which have 32 physical cores and
128GB RAM. With 32 tests in parallel, C-Reduce was plenty snappy. I can't
imagine it would run as fast with only 4 tests in parallel, but I admit I did
not test this.
(Of course, I *could* test this, for some given set of reductions, but not
today. Today I need to focus on something else.)
