[slurm-users] PreemptExemptTime

[Groner, Rob]

Ya, it did seem like there was quite a bit of overlap between what partitions could do and what qos could do.  So, choose one or the other to accomplish our preemption/suspension goals?  I'll see if I can do that.  I think I'll look at qos, because partitions don't have the preempt exempt time (unless that comes from the global setting).

Thanks.

Rob

Just a quick comment, here you're talking about both partitions and
QOS's with respect to preemption, I think for this you need to pick just
one of those options and only use those configs. For instance we just
use QOS's for preemption and our exempt time works in that case.

Hope this helps!

All the best,
Chris
