Subject: Re: [OMPI users] mca:base:select:( ess) No component selected!

Afraid I am confused. This was the entire output from the job?? If so,
then that means mpirun itself wasn't able to find a launch environment
it could use, so you never got to the point of actually launching an
orted.

Do you have ssh in your path? My best immediate guess is that you
don't, and that mpirun therefore doesn't see anything it can use to
launch a job. We have discussed internally that we need to improve
that error message - could be this is another case emphasizing that
point.

1.3 is fine to use - still patching some bugs, but nothing that should
impact this issue.
