[mpich-discuss] hydra_pmi_proxy: No such file

[Martin Gilchrist]

Here is the output of the commands you requested.

I did mean the two sentences I wrote.   The first concerned visibility of the executable when I did an ssh and the other was when I logged in directly.   I mentioned both since I thought it might be an ssh issue.

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.
