Perhaps the Sun n1GE Grid-Engine Software would be useful in this instance? The tools are really meant to schedule jobs across many machines, with many CPUs, but you could probably repurpose their scheduling tools to restrict user jobs to one CPU on a single system with similar ease. http://www.sun.com/software/gridware/ -G Regards, Gavin McDonald ======================== EVI Logistic Enterprises email: me@xxxxxxxxxxxx phone: (604) 313-3845 > -----Original Message----- > From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list- > bounces@xxxxxxxxxx] On Behalf Of George Magklaras > Sent: Tuesday, May 09, 2006 1:02 AM > To: General Red Hat Linux discussion list > Subject: Re: limiting CPU access per user > > A wrapper script that takes what is to be executed, check it out and > then dplace it to a certain CPU(s) comes to mind.
