In order to do quality assurance in a critical multicore (8) workstation, I want to run the same code in different processors but not in parallel or concurrently.
I need to run it 8 times, one run for each processor.
What I don't know is how to select the processor I want.
How can this be accomplished in Python?
Which process goes on which core is normaly decided by your OS. On linux there is taskset from the schedutils package to explicitly run a program on a processor.
Python 2.6 has a multiprocessing module that takes python functions and runs them in seperate processes, probably moving each new process to a different core.
In Linux with schedutils, I believe you'd use taskset -c X python foo.py to run that specific Python process on CPU X (exactly how you identify your CPUs may vary, but I believe numbers such as 1, 2, 3, ... should work anywhere). I'm sure Windows, BSD versions, etc, have similar commands to support direct processor assignment, but I don't know them.
