[mpich-discuss] machinefile error

[SULLIVAN David (AREVA)]

Well, I am not sure. I am using this to run mcnp5. So I think that I
would have to recompile mcnp5 against the latest version of Hydra.
Correct?

Can you try the latest version of Hydra
(http://www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/nigh
tly/hydra),
run mpiexec with the -verbose option and send us the output?
