threads and smp stuff

[Warren Togami]

Are you looking for SMP processor affinity?

  7. Does Linux SMP support processor affinity?

     Standard kernel
        No and Yes.  There is no way to force a process onto specific
        CPU's but the linux scheduler has a processor bias for each
        process, which tends to keep processes tied to a specific CPU.

     Patch
        Yes. Look at PSET - Processor Sets for the Linux kernel
        <http://isunix.it.ilstu.edu/~thockin/pset/>:

          The goal of this project is to make a source compatible
          and functionally equivalent version of pset (as defined
          by SGI - partially removed from their IRIX 6.4 kernel)
          for Linux.  This enables users to determine which
     processor or set of processors a process may run on.
     Possible uses include forcing threads to seperate proces
     sors, timings, security (a `root' only CPU?) and probably
     more.
