I wonder if there is a more efficient way doing this...
I would use an IOArray:
let l = length xs
arr <- newArray_ (0, l)
count <- newQSemN 0
let proc n x = do
rv <- runEvalIO env (reduce x)
writeArray arr n rv
signalQSemN count 1
sequence_ $ zipWith proc [0..] xs
waitQSemN count l
elems $ unsafeFreeze arr
Hmm, am I missing something here, but how does forkIO (and data
parallelism) fit in into that scheme?
Thanks,
Audrey
