TORQUE : How to prohibit using of jobs array submission for all users : qsub -t?

Question

On my torque server manager I would like to prohibit using of jobs array submission for all users: qsub -t.

In the official doc I have found pbs parameters who can manage this: max_job_array_sizeand max_slot_limit.

I would like to know if I set those parameters to 0 : qmgr -c 'set server max_job_array_size=0' and qmgr -c 'set server max_slot_limit=0' It will effectively prevent submitting array jobs ?

any other suggestion are welcomed :) maybe a rule in the sudoers file ? regards

Answer 1

qmgr -c 'set server max_job_array_size=0' and qmgr -c 'set server max_slot_limit=0' is working well.

Answer 2

Yes, if you set max_array_size to 0, all array submissions will be rejected.

Answer 3

I would simply reject any qsub -t submissions with the job submit filter. That will also give you the opportunity to give educational feedback. Your other idea about max_job_array_size seems reasonable, too, but you'll have to test it to find out if that's the case.
