I'm trying to run the same script in separate instances of octave
running on the same multiprocessor machine, and I would like to
periodically save my results to a file, and would like the script to
generate a different file name in each instance of octave. It seems like
one way to do this would be to create a file name that contains the
octave PID. Is there a way to gain access to the PID from within octave?
Any other ideas for how to accomplish this?
