We have two subclusters, A and B, in our cluster.  The machines in subcluster 
A are almost identical to those in B, the only difference being slightly 
faster CPUs.  I can send parallel jobs to either A or B (not caring which) 
using wildcards in the PE selection.

What I would like now is a job which doesn't fit in A or B to span over free 
slots in A _and_ B.  That is, only if there are not enough free slots in 
neither A nor B it is allowed to combine slots from both A and B.

Any ideas?  As I understand, sequential numbering of PEs is not available yet?
