    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    When a process is suspended because of scheduling, when its next time slice comes up, it will be reassigned to the next available core; however, you can set the affinity of a process to a specific CPU or core. Here is a link with information that may help: Linux Setting processor affinity for a certain task or process
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
