Parallelization – Call the MPI process in a terminal from the MMA laptop (RunProcess / Run) on Mac

I need to have my MMA laptop run an MPI + C process and get the result. In a simple case without MPI, it is easy:

RunProcess[{"/name_of_executable", ToString[argument]}, "StandardOutput"]

But my line is: mpirun -n #threads ./name_of_executable

How can I make MMA perform this? Thanks in advance!
