=== Launching MPI ===

ESMPy says they have a couple ways to launch mpi as noted in [http://www.earthsystemmodeling.org/esmf_releases/last_built/esmpy_doc/html/api.html#parallel-execution the API documentation]. So far, only the mpirun methods works. I cannot figure out how to run the mpi_spawn_regrid.py example. If anyone does know, please inform me and edit this section, but it might just be "You can't on a cluster" or "You can't with Intel MPI".
