[mpich-discuss] cryptic (to me) error

[SULLIVAN David (AREVA)]

Had some time to work some more on this...
I have copied the test suit folder in a NFS shared folder. The machine
file is passed by way of HYDRA_HOST_FILE=/home/dfs/shared/mpich2 make
testing, as suggested. It is still running, but the results so far
indicate I am still messing up the process somehow. 

Thanks again,

Dave

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.
