At BU we have our jobs on the SGIs split into two categories: long
running (non-interactive) batch jobs and interactive jobs, typically
whomever is sitting at the console.

What we'd like to do is reduce the batch jobs to having the lowest
impact on the interactive jobs.  It looks like one possible way to
do this is to start cron with `runon 3 cron' and maybe changing the
queuedefs file to further reduce the batch processes priority.  This
would, unfortunately, nullify any parallelism in the batch task.

My questions are

        `npri -n 15 -p pid' doesn't seem to have much effect; is
        this a bug in IRIX 3.2.1?

        will `runon 3 cron' force batch(1) jobs to run on CPU 3?

        The MP_MUSTRUN parameter of sysmp(2) only affects the calling
        process.  Will there be a way to affect an arbitrary process?

If you have a system for handling batch jobs that you think is useful,
I'd be interested in hearing from you.
