You could probably accomplish this using a job submit lua script and
some crafted QoS's. It would take some doing but I imagine it could work.

Hi All,
We are looking to have time-based partitions; e.g. a"day" and "night"
partition (using the same group of compute nodes).
1.) For a “night” partition, jobs will only be allocated resources one
the “night-time” window is reached (e.g. 6pm – 7am). Ideally, the jobs
in the “night” partition would also have higher priority during this
window (so that they would preempt jobs in the "day" partition that
were still running, if there were resource contention).
2.) During the “day-time” window (7am-6pm), jobs in the “day” queue
can be allocated resources, and have higher priority than jobs in the
“night” partition (that way, preemptive scheduling can occur if there
is resource contention).
I have so far not seen a way to define a run or allocation time window
for partitions. Are there such options? What is the best (and
hopefully least convoluted) way to achieve the scheduling behavior as
described above in Slurm?
Thanks,
Keith
