Yes.

The first is the machine where nfs host machine and the second is the other node.

Hi Martin,

Can you please stick to one configuration?  It's hard for me to tell 
when you are running in which configuration.

Can you please run the following on each of the two machines:

% hostname

% ls -l /mirror/mpich2/bin/mpiexec

% ls -l /mirror/mpich2/bin/hydra_pmi_proxy

  -- Pavan
