Yeah, Control.Parallel would be nice to have. Heck, ideally I could get the whole Haskell Platform, which would be a reasonable comparison to the huge Java and C++ libraries accessible to those languages. Out of curiosity, though, Haskell's thread-ring implementation just *tumbled * down the rankings http://shootout.alioth.debian.org/u64q/program.php?test=threadring&lang=ghc&id=3. Previously, it'd been doing most of its work on a single core, now it's spread out. Any ideas for fixin' it? (I'm going to to try using forkOnIO.)

Now how do we get those regex-dna and binary-trees programs to compile?

http://shootout.alioth.debian.org/u32/measurements.php?lang=ghc

binary-trees: Could not find module `Control.Parallel.Strategies':

--> cabal install parallel

regex-dna:

" cannot satisfy -package regex-posix"

--> cabal install regex-posix

Both are in Debian.

igouy2:

parallel, regex-posix, regex-pcre are now installed and the current compile errors are caused by the programs not the absence of required libraries -

Great work! For those keen to help out the Haskell programs, both compile failures in regexdna and binarytrees are related to the change in how parallel strategies work, as described here. http://hackage.haskell.org/packages/archive/parallel/2.2.0.1/doc/html/Contro... -- Don
