It provides MPI_INIT with the information necessary to establish MPI_COMM_WORLD over all started processes. Without the information from mpirun processes can only run as singleton MPI instances and hence all of them have rank 0 (which is OK, since each MPI_COMM_WORLD is a separate one). WebbMPI_Init (argc, argv) removes arguments passed to the MPI run-time from argc, and argv and initializes MPI. AFAIK it is the only way to clean argc and argv so if you need these to have no MPI arguments you need to use it. MPI_Init () can be used in more situations that MPI_Init (argc, argv).

It does this because mpirun is launching 4 copies of a shell script which doesn't understand MPI communication semantics. If you can somehow get launch mpirun on a script, then remember (1) the script is running in the local "head" node environment ...
