You could build something with the posix-shm egg, and the posix unit. If you need locks, there’s the posix-semaphore egg.

I guess you could spawn a process pool and send these processes a thunk that calculates their part and send back the result. You could use s11n egg for that, I believe. I’m not sure it would be faster than the regular functions though. Do you recommend any specific way to create the pool and especially to communicate between the processes? About the speed, I'll test and report the results. Thanks! Arthur
