    Subject[HOWTO] Emulate processor sets (pset) for linux kernel 2.5/2.6

    A while ago, I was banging on about kernel patches and whatnot to implement the
    equivalent of "pset" functionality. After some shoves/pointers from Robert and
    Miquel, I found that init(8) has the concept of an initscript(5), so that the
    trivial solution to my problem is to say:

    # initscript Executed by init(8) for every program it
    # wants to spawn like this:
    # /bin/sh /etc/initscript <id> <level> <action> <process>
    taskset -p 1 $$
    eval exec "$4"

    and then modify the relevant programs to set their affinity to the other
    processors as required. Bingo!

    Hope this helps, Shaheed
