[Condor-users] determine machine matching order

Assuming someone submits a generic vanilla universe job with no
specifics, how does condor determine the order which to dole out the
machine matches, assume defaults (out of the box condor setup)?  And
can I dictate it?

To be more specific (here's what i tried), our condor pool is
comprised of three classes of machines

Dedicated Condor only nodes
HPC Clusters
Generic computing nodes

I'd like to ensure that if someone submits jobs with no requirements
expressions, that nodes are matched in the above descending order.

I believe currently, it's matching based on kflops, which in our case
means matches take place all over the place.

I did a condor_status -l node | grep -i rank


where nodepriority is a decreasing number starting from top to bottom
of the above list

and condor_q -l <jobid>.<processid>


I'm not sure if I've missed something or not.

Is there a better way to accomplish this?
