Python multiprocessing Queue failure

Question

I create 100 child processes

proc_list = [
    Process(target = simulator, args=(result_queue,))
    for i in xrange(100)]

and start them

Answer 1

My solution to multiprocessing issues is almost always to use the Manager objects. While the exposed interface is the same, the underlying implementation is much simpler and has less bugs.

from multiprocessing import Manager
manager = Manager()
result_queue = manager.Queue()

Try it out and see if it doesn't fix your issues.
