I've always thought that the tight integration merely removed the
need for a hostfile, or equivalent, to be specified?
I've been basing this belief on the examples here:
http://www.open-mpi.org/faq/?category=running#qsub-notify
where, in all three examples, both the SGE submission script's
#$ directives and the mpirun commands invoked, specify the
number of processors but there's no hostfile/list.
