Hi Jason, I wanted exactly the same and was confused exactly like you. For a while it did not work, regardless of what I tried, but eventually (with some help) I figured it out.
What I set up and it is working fine is this globally PreemptType = preempt/partition_prio PreemptMode=REQUEUE and then individually each partition definition has either PreemptMode=off or PreemptMode=cancel It took me a while to make it work, and the problem in my case was that I did not include the requeue line because (as I am describing) I did not want requeue, but without that line slurm preemption simply would not work. Since it's overridden in each partition, then it works as if it's not there, but it must be there. Very simple once you know it.
