[slurm-users] Limit a partition or host to jobs less than 4 cores?

Untested, but a combination of a QOS with MaxTRESPerJob=cpu=X and a partition that allows or denies that QOS may work. A job_submit.lua should be able to adjust the QOS of a submitted job, too.

    Probably the best way to accomplish this is via a job_submit.lua
    script.  That way you can reject at submission time.  There isn't a
    feature in the partition configurations that I am aware that can
    accomplish this but a custom job_submit script certainly can.
