[slurm-users] [External] Limit usage outside reservation

[Burian, John]

This doesn' t help you now, but Slurm 20.11 is expected to have "magnetic reservations," which are reservations that will adopt jobs that don't specify a reservation but otherwise meet the restrictions of the reservation:

    If you want to apply different limits inside and outside the 
    reservation, you'll need to setup different QOSes for inside and outside 
    the reservation. One way to do this in a way that is transparent to the 
    users is to use the job_submit.lua script to check if the reservation 
    has been requested, and set the QOS based on that.
