I'm learning Haskell and I'd like to write some multithreaded programs now to see the performance gains from that in a functional language. I can find some references to it on the internet but never a proper introduction to it. Can anyone point me to a guide which is understandable for someone who knows the syntax fairly well, but is not a wizard in Haskell?
I gave a 3 hour course on this topic at DEFUN 2009. The slides and code are online: Multicore Haskell Now!
