[slurm-users] job priority keeping resources from being used?

[Brian Andrus]

I ask if you are specifying it, because if not, slurm will assume a job 
will use all the memory available.

So without specifying, your big job gets allocated 100% of the memory so 
nothing could be sent to the node. Same if you don't specify for the 
little jobs. It would want 100%, but if anything is running there, 100% 
is not available as far as slurm is concerned.
