Running MPI Programs
The MPI-1 Standard does not specify how to run an MPI program, just as the Fortran standard does not specify how to run a Fortran program.
In general, starting an MPI program is dependent on the implementation of MPI you are using, and might require various scripts, program arguments, and/or environment variables.
mpiexec <args> is part of MPI-2, as a recommendation, but not a requirement
- You can use mpiexec for MPICH and mpirun for SGI’s MPI in this class
