Are you certain? Just tried man poll on one of the MacOS X

Satnam,
Does anyone know of any other work on implicitly
parallelizing functional programs for fine grain parallel execution?
The skeletons community implicitly replace higher-order functions with
parallel implementations:

Hi,
Both variants of the strict zipWith solved the gibs problem I posed:
gibs = 1 : 1 : f gibs (tail gibs)
where f (x:xs) (y:ys) = z `seq` z : f xs ys
where z = min (x + y) 10
by Simon MArlow
and
zipWith' f (x:xs) (y:ys) = let z = f x y
Axel,

However, they do not directly solve my problem in the bigger program which
still has the same linearly growing memory requirement. The problem seems to be
very, very hard to find. I suspect it is related to lazyness as in the gibs
example, but I just cannot put my finger on the code that
There are plenty of academic papers about Haskell, and plenty of informative
pages on the Haskell Wiki. But there's not much between the two extremes. The
Monad.Reader aims to fit in there; more formal than a Wiki page, but less

Yaron, would you mind sharing the reason your firm

For others, I would love to organize an informal

any. If you are interested, please contact me and
I'll try to make it happen.

I started the quantitative research group, and I knew OCaml very well,
and didn't know Haskell except by reputation. As to the merits, it is
my general impression
Yaron,
This is probably out-of-topic, but: are you, or have you considered, using
the .NET implementation of OCaml. I managed - painstakingly - to integrate
it into a toy .NET project of mine, using .NET Direct3D, and see some virtue
in that combination.

Has anyone tried/been successful on developing such a binding?
