The mpirun scripts are specific to each device, ie the mpirun.ch_p4 is
not the same as mpirun.ch_gm or mpirun.ch_mx. As long as you don't use
an mpirun from a different device, it should be safe ti mismatch
versions, even more likely between minor versions (1.2.X).

It won't work, ch_p4 and ch_gm use very different spawning process.
