Hi all:

I have a user who is requesting that the scheduler system be modified
such that jobs are not packed in by default.  On our cluster, it is
rarely running at or near 100%.  This user would prefer that only one
job is run per node unless all the nodes are full; at which point, it
can start packing things in more closely.

I thought this is most aptly controlled by NODEALLOCATIONPOLICY, which
I have set to MINRESOURCE.  I do have some nodes that have IB, and
some nodes that are 16-core nodes with twice the ram per core, but the
majority of my nodes are just 8-core/8GB ram nodes, and those are fine
for the majority of jobs/users.  So I want to make sure by default,
those are used unless they don't meet the specified resources, or
they're already busy (and the other nodes aren't).

So, Is NODEALLOCATIONPOLICY the setting I should be looking at?  What
exactly is MINRESOURCE's policy for job packing?
