Yes. Start qmon, go to host configuration, go to execution
host.  Put a value in the "Consumables/fixed hosts" field. 
For instance "BIT64 TRUE".  Then you put a condition
on the qsub command (using the -l option) so that
64 bit jobs only go those nodes where BIT64 is true.

For more info one of the SGE lists would probably be a better
place to ask.
