Subject: Re: [OMPI users] mpirun fails on the host

The source of the problem has been determined, but not wholly understood, by
fully disabling the firewall on the host to the internal network. Parallel
jobs involving the host and nodes launched from a node were successful while
those launched on the host were apparently blocked by the firewall. Would
the former only involve the use of the ssh port on the host while the latter
involve other ports?
