[slurm-users] Limit nodes of a partition without managing users

[Brian Andrus]

Most likely, but the specific approach depends on how you define what 
you want.

For example, what if there are no jobs in high pri queue but many in 
low? Should all the low ones run? What should happen if they get started 
and use all the nodes and a high-pri request comes in (preemption policy)?
What about the inverse of that? What if you get a steady stream of 
high-pri jobs? How long should low-pri wait before being allowed to run? 
Does it matter if it is all the same user?1

You can handle much of that type of interaction with job priorities and 
a single queue. As you can see, the devil is in the details on how to 
define/get what you want.
