Test queued, but I will be offline for the next 3 hours.

Test FAILed.
See http://bgate.mellanox.com/jenkins/job/gh-ompi-release-pr/1603/ for details.

[edgargabriel]

Not sure I see a reason in the log files why the Mellanox build failed.

Looks like another signature of the mindist failure.

[rhc54]

no, that's something different

[hppritcha]

@jsquyres now that mlnx is happy I think this is ready to go.
