[mvapich-discuss] mvapich2-1.2p1 does not run successfully mpi1 application

[Dhabaleswar Panda]

Can you provide some details on your cluster (computing platform and
network adapter), your MPI1 application, how you configured mvapich2-1.2p1
(default build or with any additional features) and whether you are
running it with any additional runtime environmental variables.  Without
such information, it is very hard to investigate what is going on here.
