The whole point of mpiexec is to integrate MPI with a batch system,
so outside of a batch environment it's not going to work.  (The -kill
functionality relies on the batch system for signal delivery, for
instance.)

I don't know if SGE has a publicly documented API equivalent to the PBS
tm interface.  I suspect such an API exists inside SGE, but my cursory
search of the SGE docs didn't turn up anything.  (SGE is pretty bad in this
regard, IMHO.  The Maui devs had an extremely hard time adding an SGE driver
to Maui because SGE also didn't have a publicly documented scheduler API
until very recently.)
