I looked at the 1.5 code, and mpirun is reaping all OMPI_ params from the environ and adding them to the app. So it should be getting set.

I then ran "mpirun -n 1 printenv" on a slurm machine, and verified that indeed that param was in the environment. Ditto when I told it to use the rsh launcher.
