[mpich-discuss] cryptic (to me) error

[Dave Goodell]

Based on what you've sent us in the past, your mpiexec is actually running mcnp.mpi.  The error occurs during an MPI_Comm_dup somewhere in that code.  Running the test suite over the network will help us figure out whether there is a problem with your network.
