[mpich-discuss] hydra_pmi_proxy: No such file

[Martin Gilchrist]

Yes the two are different.
 
The one where the proxy is not found is produced when mpiexec is invoked on the main computer where I have installed nfs and done all the make and make install of mpich2.   The one with the mpiexec not found is produced when mpiexec is invoked on the node.

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.
