<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-aqj">6pm – 7am</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-aqj">7am-6pm</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).<o:p></o:p></a></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="mso-bookmark:_MailOriginalBody">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? <o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">Thanks,<o:p></o:p></span></p>
