I assume you are using the multifactor plugin and I don't think normal
users are intended to be able to set the priority themselves.  The
danger would be that all users would increase their priority as much as
possible.

You probably what to look at QOS.  This would allow you to, say, define
a high-priority QOS which had a priority bonus but also limit on how
many cores per user can uses the QOS.  That way

Cheers,
