[Mauiusers] effectively scheduling a heterogenous cluster

We have been running Torque/Maui for some time on a cluster of
identical resources: 20 nodes with 8-cores at 2.67GHz with 48GB each. We
are now adding 4 new nodes with 24-cores at 2.0GHz with 256GB each.
Obviously large jobs will get routed to the new nodes, but how can we
prioritize the queue for small jobs such that they (a) fill up the
smaller/faster nodes first without (b) *preventing* them from using the
larger/slower nodes if (i) the large nodes are available and (ii) there
are no large jobs in the queue?
