I think I solved my problem.
To prevent that users use more than their resources requested, I use cpuset with torque.
On each executable nodes, all process are running under PBS have /proc/<PID>/cpuset with the definition of cpuset, other process have only / in this file.
In crontab I check all user process and I kill all jobs are not running under PBS .

Thank for your reply, I think that it can be my solution.
Could you show an example of script please ?

There are no quotas present on the scratch file systems. So for you to be getting a quota limited message tells me that somehow the tool you're using is trying to write something to your user home directory. You should look to clean up some of your home directory to bring yourself below your quota limit .

I have a script that I run from /var/spool/mom_priv/prologue whenever a josb that requires all the cores on the node. This script kills any user level processes that are not the job owner or a torque manager.
This gets rid of any effect of users who should not be logged on to the compute node, that is who have just ssh'd in rather than using qsub -I
I clean out scratch space on exit with epilogue if it is a dedicated job.
You could couple this with techniques to prevent ssh logins durin the job (For jobs which dedicate the node, have prologue disallow logins from other users, and restore normal function on exit.)

Subject: [torqueusers] How to run mpirun of intel on torque
I am sorry, but my english is really sad. I thank you for your patience for that.
I installed TORQUE 4.1.0, with MAU 3.3.1. I compiled OPENMPI with option --with-tm=/usr/local/torque.
I disallowed ssh connections for my users on executable nodes. In /etc/ssh/sshd_config I set AllowGroups root admin This works fine.
But now, I install MPI Intel Librarie and Ifort.
When I open a interactive pbs session:
qsub -I -l nodes=2:ppn=8
I am connected on a node.
I run mpi job
mpirun -genv I_MPI_FABRICS_LIST tmi ./my_program
But it can not start, because it cannot connect on the other node.
If I append users in AllowGroups of /etc/ssh/sshd_config it works.
But if I do this, all users can connect on executable nodes, without use torque, and this is bad.
How can I do to disallow ssh connection without torque or make mpirun of intel works like openmpi, without ssh connection allowed for users ?
