Thanks for the report. Just checking - did you compile MVAPICH with
the ch_gen2 interface or sockets? If you did compile MVAPICH with
sockets, could you recompile with ch_gen2?

It could be that you have compiled Amber with one version of MVAPICH y
and trying to run it with another.

MVAPICH-1.1.0 version is old, may we request you go update to later
MVAPICH-1.2-rc1 or even better MVAPICH2-1.4.1.
