working example of multiprocessing.Queue

Question

I am looking for a working example of multiprocessing.Queue after being pointed to it from this question: Python utilizing multiple processors

I came across this, but it only seems to use one of my 12 processors even when I change num_processes=12. I also changed num_jobs = 200000 so that it wouldn't complete so fast.

Can someone tell me what's wrong with that example or point me to one that works?

It seems like that was just a bad example where it took longer to put together the list of work to do than it actually took to do the work. I put together something else with a nearly identical Worker class and got it to utilize all processors. — eric.frederich

There are examples in the Python docs.

Do these examples work? If not, it may be that the problem itself is not Python, but something else instead.
