(My previous email showed up as mangled in http://www.haskell.org/pipermail/haskell-cafe/2007-November/034717.html; I think the PGP signature was the problem; I removed it and sent it again, but it was put into moderation for size, and hasn't been released yet - so I'm sending this a third time but I'm removing attachments so it'll be under the annoying 20k size limit)
So I've been trying to get my QuickCheck tests to run in parallel. I did take a look at Don's Parallel QuickCheck library http://www.cse.unsw.edu.au/~dons/pqc.html, but I didn't like how much code it had in it and I figured it'd be a good exercise to try to do myself.
Did you compare it against the multicore performance of the original pqc? (Which I've found fairly good). The trick is to ensure enough work is done per thread, so you don't get overwhelmed by communication. -- Don
