[Haskell-cafe] CPU simulation library?

I want to simulate various process/thread scheduling algorithms for a small project. I'm trying to compare the performance versus power consumption of several algorithms. If anyone knows of some Haskell code along those lines I'd love to hear about it. Thanks in advance! Justin p.s. I can find non-Haskell code on my own - I'm hoping there is something in my favorite language, but any particularly good suggestions are also welcome.
