[slurm-users] Defining constraints for job dispatching

I have found that when user A is running a fluent job (some 100% processes
in top) and user B decides to run a fluent job for his own, the console
window of fluent shows some messages that another fluent process is running
and it can not set affinity. This is not an error, but I see that the speed
is somehow low.

Think that when a user runs "srun --x11 .... script" where script launches
some fluent processes and slurm put that job on compute-0-0, there should
be a way that another "script" from another user goes to compute-0-1 even
if compute-0-0 has free cores.

Is there any way in slurm configuration to set such a constraint? If slurm
wants to dispatch a job, first see if process X is running there or not.
