Re: [OMPI users] spawn failed with errno=-7

[Ralph Castain]

Hi Jens What this says is that the system was unable to launch your processes on the specified machines. The usual reason is a lack of ssh authority on the remote machines. You might check the following FAQ to see if it is of help: http://www.open-mpi.org/faq/?category=rsh Let us know if that solves the problem. I'm assuming that you are using an rsh/ssh launcher and not in some other kind of cluster - if that's incorrect, please let us know.
