Errors while trying to run ssh localhost.localdomain -n /bin/ls /usr/local/mpich-1.2.7p1/bin/mpichfoo
Unexpected response from localhost.localdomain:
--> /bin/ls: /usr/local/mpich-1.2.7p1/bin/mpichfoo: No such file or directory
The ls test failed on some machines.
This usually means that you do not have a common filesystem on
all of the machines in your machines list; MPICH requires this
for mpirun (it is possible to handle this in a procgroup file; see
the documentation for more details).

Other possible problems include:
The remote shell command ssh does not allow you to run ls.
See the documentation about remote shell and rhosts.
You have a common file system, but with inconsistent names.
See the documentation on the automounter fix.

Have you set up passwordless rsh or ssh between the machines. I think MPICH uses rsh by default but can be configured to use SSH. You can use /etc/hosts.equiv so that you can setup passwordless RSH (less secure) or set up SSH host keys for passwordless SSH (or use shosts.equiv) (more secure mechanism). BTW, unless you need MPICH-1 specifically, version 2 is out and either it or OpenMPI will likely give you better performance.
