This discussion definitely does not belong on the Haskell-Beginners list. Besides not being a topic for beginners, being there is keeping it under the radar of many or most of the people who work on these things in Haskell.
I am moving the discussion to the GHC users list, as suggested by Antoine. For those joining us in progress, the first part of the thread starts here:
http://www.haskell.org/pipermail/beginners/2009-December/003045.html
I am not familiar with the GHC users list but is this discussion about basic parallelism really more relevant here? The interesting bits aren't GHC specific...
Discussion about support for parallelism in GHC is very on-topic here. Parallelism is not part of the Haskell language per se, and although the basic par/pseq are not implementation-specific, using them effectively may require knowing something about the implementation. For instance, in GHC 6.12 we reduced some overheads and made it possible to parallelise some fine-grained parallel problems that previously resulted in slowdown on a multicore. (I'll respond to the particular issues raised in the earlier message later, I'm still on holiday right now)
Also, is this list censored like the Haskell Cafe or is it open?
Haskell lists are only ever moderated on an ad-hoc basis as necessary. We've never used moderation on this particular list. Cheers, Simon
