[torqueusers] pbs_sched and one or more many CPU nodes.

I'm managing a cluster and use pbs_sched.
I have a reasonably large (144 node) homogeneous cluster of 4 processor/8GB
nodes. It is running well.
I now need to add at least one, perhaps more nodes which are
32 processor/128GB nodes.
One way is to treat this as a separate (maybe just single node) cluster
the other is to incorporate it into the existing queuing system.
Has anyone incorporated nodes with such a large disparity in capability
into a single PBS structure?
Ideally one would want only jobs > 4 cpus and < 32 cpus to run on
Has anyone done this with pbs_sched?
If so, can you dump the qmgr setting with
qmgr -c 'p s' > state_file
and share it with me, and maybe the nodes file if that is also needed?
