I don't know, since I've never had an infiniband system to play with. I'm not
opposed to people using system-installed MPI's at top supercomputer sites,
although it would be helpful to know how do to things "by hand", and to
incorporate that knowledge into the appropriate scripts. If your own builds
are not working, it would be great to figure out why. Otherwise, we're
dependent on a "black-box" supplied by some vendor....
