[Mauiusers] node attributes / resource specification

I wonder if anyone knows if its possible within MAUI to specify a node
attribute on a node for example 'available for MPI' but when there are no
MPI jobs in the system that it starts up normal jobs.  Then when an MPI job
comes in requesting all the cores on the MPI node that it drains out the MPI
node and runs the MPI job on the 'available for MPI' .

I ask because we have shared cluster and only a few MPI jobs will be
submitted.  So I wanted to nominate a few nodes with better interconnects
and allow then to be MPI specific but also be available to the main cluster
when not in use.

Thanks in advance for any tips.
