I suspect this has something to do with your simplifications, but for the life of me I cannot see what the purpose of the JobQueue is?

  1. Jobs/Nodes get queued onto it by the first set of threads.
  2. Another thread monitors it, pulls them off, sets a random value into them and then sets them into a shared hash in the main thread;
  3. But then you do nothing with that?

You seem to be getting the "results" in the main thread via the results queue; so what is the jobs queue/nodes hash for?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
