Are these instances of an external program or simply instances of some python code? If its an external program and you are on *nix you may not need threading at all simply call os.system() with the program in the background. Or if you need to communicate with the program use threading and os.popen() (or the subprocess module and its Popen class) to start the utility. The utility as a separate process will be able to run on different CPUs even though the threads all run in Python interpreter on one CPU. If OTOH the utility is python code then you will need to look at using fork/exec or spawn. I touch on os.fork in my inter-process comms topic of my tutor. In your case instead of setting up a client/server you would simply run your utility functions. But forking does give you the potential to communicate results back to the parent process via a pipe...
