You can set a flag like -np 8 in your mpirun or relevant commands to tell your programs to use 8 cores. If you have meep_mpi lib compiled and installed successfully, then in _BASH_ use the command shown in MEEP website like export PKG_CONFIG_PATH=/path/to/pkgconfig/ mpicxx `pkg-config --cflags meep_mpi` foo.cpp -o foo `pkg-config --libs meep_mpi` Please read some MPI manuals such as ones in MPICH, MPICH2, LAM/MPI or OPENMPI, and the tutorials in MEEP website.
