You will get whatever cores Slurm can find which will be an assortment
of hosts.

sorry to hijack, but we've been considering a similar configuration,
but I was wondering what happens if you don't set a processor type?
Will it scatter across types?

Yes, Boolean constraints do work with minimal configuration. We
run mostly MPI jobs on our cluster and want our jobs to run on a
single processor type. We assign the processor types as a feature
and then the sbatch requests —constraint=[wes|san|has|bro] to run
on whatever processor type is free. Works great.

Hello,
We currently use an in-house customized version of Torque and an
in-house scheduler. I'm now considering Slurm instead. We have a
feature in our scheduler where by users can submit jobs with
multiple-prioritized job specifications (constraints). For
example, a job can request 4 nodes of type X with 16 cores per
node OR 2 nodes of type Y with 20 cores per node. The scheduler
will prefer the first job spec but may use the second job spec if
the first can not be satisfied within certain QoS limits.
I saw some ability to use boolean constraints in the docs for
Slurm, but would like to know if this behavior is possible out of
the box.
Thanks,
Kevin
