Hi,
I doubt that you can do this kind of things at application (programming)
level. Ensuring that all cores are used at best is the responsibility of
the operating system in the person of its scheduler. This is because
only the O.S. can be aware of everything running on the system beside
your program. Thus I believe the answer to your question is not. AFAIK
the kernel scheduler in Linux does a god job, even if I never had the
occasion of using it on that many cores :)
