Thank you for the help. I did include path to orted in my .tcshrc

mac2, but I put the path at the end of the file. It is interesting
that when
I logged into mac with ssh, the path was included and orted was in
my path.
But when I ran "ssh mac2 which orted", orted was not found. It
finds orted
only after I move the path from the end of .tcshrc to the beginning
of the
file. Strange. Again, thanks and at least I may make MPI work.
Do you have a test like if ( $?prompt ) exit towards the end of
your .tcshrc? Most .tcshrc files do, and the end is only evaluated
for interactive shells (which the one to start the orted is not).
This is probably why moving it to the top helped.
Anyway, glad to hear things are working for you.

File my_hosts looks like

The orted is definitely on my path on both machines. Any idea?
Help is
greatly appreciated!
I'm guessing that the issue is with your shell configuration. mpirun
starts the orted on the remote node through rsh/ssh, which will start
a non-login shell on the remote node. Unfortunately, the set of
dotfiles evaluated when a non-login shell is different than when
starting a login shell. The easiest way to tell if this is the issue
is to check whether orted is in your path when started in a non-login
shell with a command like:
ssh remote_host which orted
More information on how to configure your particular shell for use
with Open MPI can be found in our FAQ at:

Hope this helps,
