All, I have a simple Haskell P2P library that I've been playing with in simulations of 20 to 600 nodes. To run the simulation there is a Haskell thread (forkIO) for every node in the system, one that starts up all the nodes and prints the info (so prints aren't mangled), and one that acts as the router.
Before its mentioned - I understand the best way forward would be to refactor the code into IO-less 'algorithm' sections and other sections that perform the needed IO when I'm not simulating. I know this would allow me to declare what order each node runs in and would free me from the scheduler. I'd like to do that if its practical... but! None-the-less, here I am saying that there are many interesting little simulations that could be done without refactoring and the correctness isn't altered by the order of operations (not if the nodes behave properly, the slight variation is actually a good test). What I would like to know is are there any plans for GHC to incorporate user-definable scheduler? It would be useful in numerous instance beyond this poor example; I know user scheduling was briefly mentioned in Li's paper but haven't seen or heard of any interest from others since then.
