Re: [Haskell-cafe] FFI and concurrency

Hello Johannes, Friday, September 10, 2010, 2:25:58 PM, you wrote: just forkIO in threaded RTS works for me. try: main = do forkIO expensiveCalc forkIO expensiveCalc forkIO expensiveCalc expensiveCalc

What's the story with FFI calls and concurrency?

I have an expensive calculation performed by some C function, which I call from Haskell land. (This works like a charm.)

I have several cores available. How could I run several of these calculations in parallel?

Thanks, Johannes.
