Yup, PriorityTier is what we use to do exactly that here. That said
unless you turn on preemption jobs may still pend if there is no space.
We run with REQUEUE on which has worked well.

Hi David,
as far as I know, you can use the PriorityTier (partition parameter)
to achieve this. According to the manpages (if I remember right) jobs
from higher priority tier partitions have precedence over jobs from
lower priority tier partitions, without taking the normal fairshare
priority into consideration.

Hello.
We have a small set of compute nodes owned by a group. The group has
agreed that the rest of the HPC community can use these nodes
providing that they (the owners) can always have priority access to
the nodes. The four nodes are well provisioned (1 TByte memory each
plus 2 GRID K2 graphics cards) and so there is no need to worry about
preemption. In fact I'm happy for the nodes to be used as well as
possible by all users. It's just that jobs from the owners must take
priority if resources are scarce.
What is the best way to achieve the above in slurm? I'm planning to
place the nodes in their own partition. The node owners will have
priority access to the nodes in that partition, but will have no
advantage when submitting jobs to the public resources. Does anyone
please have any ideas how to deal with this?
Best regards,
David
