For whatever it's worth, basic MVAPICH tests like osu_bw work fine for
me with two and even four processes on two x86_64 machines.

Without more data like a traceback from a core file or something like
that, it's going to be very difficult for anyone to debug this.

Also, it might be worth contacting the MVAPICH developers by emailing
mvapich_request -- they are much more likely to be able to help than
the openib-general community.
