Hi Michael, thanks very much for your swift reply. So here we would have to convince the users they'd have to specify this when submitting, right? I.e. 'sbatch --exclusive myjob.sh', if I understand correctly. Would there be a way to simply enforce this, i.e. at the slurm.conf level or something? Thanks again!

Hi, for a smallish machine that has been having degraded performance we want to implement a policy where only one job (submitted with sbatch) is allowed to run and any others submitted after it are supposed to wait in line. I assumed this was straightforward but I can't seem to figure it out. Can I set that up in slurm.conf or in some other way? Thank you very much for your help. BTW we are running slurm 15.08.7 if that is at all relevant. Best wishes, Dr. Rutger A.
