Running methods on different cores on python

Question

Is there any easy way to make 2 methods, let's say MethodA() and MethodB() run in 2 different cores? I don't mean 2 different threads. I'm running in Windows, but I'd like to know if it is possible to be platform independent.

edit: And what about

http://docs.python.org/dev/library/multiprocessing.html and parallel python ?

Answer 1

You have to use separate processes (because of the often-mentioned GIL). The multiprocessing module is here to help.

from multiprocessing import Process
from somewhere import A, B 
if __name__ == '__main__':
    procs = [ Process(target=t) for t in (A,B) ]

    for p in procs: 
        p.start()

    for p in procs: 
        p.join()
