Actually, that isn't totally correct and may point to the problem. The
mpirun cmd itself points to a version of OMPI located in /opt/openmpi.
The error messages are clearly from a 1.3+ version - they look totally
different for 1.2
However, the prefix passed to the backend nodes points to /usr/lib, and
indeed looks like a 1.2.8 version.
Waris: is this a mistype? Are these two versions actually the same?
If not, that would explain the problem - you can't mix OMPI versions. As
written, the cmd line has the potential to mix one version of mpirun
with another version of the daemons.
