Also worth to mention: "job_is_first_task" will allow in addition the local call of `qrsh -inherit ...`,  as this depends on the parallel library whether it makes a local call or not. I.e. you have N-1 (TRUE) or N (FALSE) `qrsh -inherit ...` calls allowed.

The above error is coming from Hydra. So do you mean that Hydra is 
throwing an error on the "cluster that works fine" when mpiexec is 
placed within the SGE job script?

mpiexec should always be called from within the SGE job script.
