[mvapich-discuss] troubles in running MPI job over RoCE, with mvapich2-1.6 shipped with OFED1.5.3.2

[Devesh Sharma]

Yes Jonathan I have done this change...and the command worked. Not able to
get output of /bin/hostname though. But it did not showed the usage msg.

Do I  need mpi pass code file in the home of the user as part of mpi env
setup?
