It really depends on the supercomputer and what MPI implementation they are using. For example, with OpenMPI, there is a program called "mpirun" that you use to run MPI programs, and which takes an argument specifying how many processes to use. Your supercomputer documentation should have information on running MPI jobs. Note that when you run meep-mpi, it prints out how many processes it is using in the first line of output, so you can see whether you are running it correctly.
