<div>Hi All,<br>
<br>
We are looking to have time-based partitions; e.g. a"day"
and "night" partition (using the same group of compute
nodes).<br>
<br>
1.) For a “night” partition, jobs will only be allocated
resources one the “night-time” window is reached (e.g. <span
class="gmail-m_-2499498420658111713gmail-aBn"><span
class="gmail-m_-2499498420658111713gmail-aQJ">6pm –
7am</span></span>). 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).<br>
<br>
2.) During the “day-time” window (<span
class="gmail-m_-2499498420658111713gmail-aBn"><span
class="gmail-m_-2499498420658111713gmail-aQJ">7am-6pm</span></span>),
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).<br>
<br>
</div>
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? <br>
<br>

Thanks,<br>
