Dave what version of Grid Engine are you using?
The plm checks for the following env-var's to determine if you are running Grid Engine.
SGE_ROOT
ARC
PE_HOSTFILE
JOB_ID

If these are not there during the session that mpirun is executed then it will resort to ssh.

I've just tried 1.5.3 under SGE with tight integration, which seems to
be broken.  I built and ran in the same way as for 1.4.{1,3}, which
works, and ompi_info reports the same gridengine parameters for 1.5 as
for 1.4.

The symptoms are that it reports a failure to communicate using ssh,
whereas it should be using the SGE builtin method via qrsh.

There doesn't seem to be a relevant bug report, but before I
investigate, has anyone else succeeded/failed with it, or have any
hints?
