title: Which python mpi library to use?
body: <p>I'm starting work on some simulations using MPI and want to do the programming in Python/scipy. The scipy <a href="http://www.scipy.org/Topical_Software#head-cf472934357fda4558aafdf558a977c4d59baecb" rel="noreferrer">site</a> lists a number of mpi libraries, but I was hoping to get feedback on quality, ease of use, etc from anyone who has used one.</p>
