I don't see any problem with this setup, as long as you don't intend
to run two execd on each node - one for each sub-cluster. Then you
would need different ports.
If you have two qmasters on two different machines, this would also
work when both cells are called "default". Two have different cells
is more appropriate when you want to have two different qmaster
running on one machine, which should in addition share the same SGE
When you think in long terms, be only sure to have a common namespace
for the users across the two clusters, maybe an external NIS server.
