[slurm-users] Multiple job constraints

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.
