Hi Savannah,I've been compiling resources to include in our guide to MPI and I came across a link that isn't working on your site.
It's on this page: http://savannah.gnu.org/task/?func=detailitem&item_id=5606
I'm getting an error message when I visit this link: http://www-unix.mcs.anl.gov/mpi/mpich/
If you are planning on updating this page on your site, perhaps our guide to MPI - http://wiht.link/MPIguide would make a suitable replacement.
