I have a number of compute-bound graphics programs written in Haskell.
(Fractal generators, ray tracers, that kind of thing.) GHC offers
several concurrency and parallelism abstractions, but what's the best
way to use these to get images rendered as fast as possible, using the
available compute

You should just try: no one can say if p
Block, line or 'beam' decomposition tends to work well for raytracing tasks,
because they tend to give you a good cache locality and don't create a
ridiculous explosion of parallel jobs.
You'll need to do some tuning to figure out the right granularity for the
decomposition. But typically a few hu

side-effects are bad! ;-)

Works for me :-)

There doesn't need to be a sound theoretical foundation
This is seriously cool stuff!!!
Maybe it's time to start a "Haskell Demo Scene" :-)
(what's a "demo scene"? See http://en.wikipedia.org/wiki/Demoscene )
PS: Note that Conal Elliott also was generating GPU code using Haskell
with Vertigo back in 2004: http://conal.net/papers/Vertigo/
On Thu,
Awesome!

This is just awesome indeed.
You should create a haskell wiki page about that, so that "beginners" could
see Haskell can do that (TM) (yeah, some beginners doubt of it).

I'm impressed, too!
