can you please execute:
$ ompi_info | grep grid
MCA ras: gridengine (MCA v2.1.0, API v2.0.0, Component v2.0.0)

For testing purpose you can just use:
$ qsub -pe orte 160 -j yes -cwd -S /bin/bash <<< "mpiexec hostname"
It will detect the number of granted slots automatically. I usually suggest not
to use "-V" as one can never be sure what the actual environment will do to the
job, and even worse in case the job crashes one week after the submission, one
won't recall that settings at submission time. I put all necessary definition
of environment variables in the jobscript instead.

In principle this can be redfined on a per node basis. Do you gave custom
settings, i.e.:
$ qconf -sconfl
If yes, what's inside? In case all nodes are the same you can even remove the
individual configuration with `qconf -dconf node001` and alike.

The above entry must be set to TRUE to allow a `qrsh -inherit ...` to connect
to the slave nodes.
