Try the man pages for the taskset command on Linux 2.6 machine. There are
also system calls sched_setaffinity() and sched_getaffinity()

have no problem as such that many user might log on to the cluster
simultaneously. Suppose that I am free to use cluster dedicatedly for my single
parallel application.
1) Do I really need a cluster scheduler installed on the cluster? Should I use
scheduler?

To solve the problem below that toon describes where the scheduler
believes 4 jobs can co-exist on a single node but they cannot because
they are I/O (disk) bound jobs and will thrash the system.
There are several ways in LSF, here are two...

especially when the users password changes and the job scheduler does not

Regarding the 'borgification' of MPI on Windowsthere is an opening
for them to do this. MPI did not define how you start the tasks when

Hi Eric,
You may want to send the Perceus guys an email and ask them how hard it

Hi Mark,
We are going through a similar experience at one of our customer sites.
They are trying to run Intel MPI on more than 1,000 nodes. Are you
experiencing problems starting the MPD ring? We noticed it takes a
