Both those statement sound identical.  Did you mean to add a "not" 
somewhere there?

This is not an executable permission issue.  It should say "Permission 
denied" for that, not "No such file or directory".

Can you send me the following output?

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

% /mirror/mpich2/bin/mpiexec -n 2 -f machinefile ./cpi

I'm having trouble believing that you can see the file, but are getting 
the following error, so I'd like to see that myself :-).  Of course, 
it's always possible that it's some weird NFS-ness that I'm not aware of.
