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. -- Kevin M.
