There is a suggested approach to running one job per node on this thread
from the SGE mailing list (works only on SGE 6):
We've tried this successfully here. Jobs get scheduled at one per node
if sent to the special 1-slot-per-node queue. Other 2-slots-per-node
queues are subordinated to this one so jobs sent to these queues get
scheduled in the default way, but waiting first for anything running on
the 1-slot-per-node queue.
In the case of blast, it can also be used in combination with the "-a"
option to use 2 processors for the blast run.
