Yeah; I wasn't surprised either. That's why I just re-compiled the
app & ran it. Then it worked.

I'm suspicious (but can't prove it) that the opensm subnet manager
(running on another node, and on the Mellanox 'ib gold' stack) wasn't
working properly. The problem is that I have nothing to back up the
suspicion. But the behavior was consistent to what I'd see if there
was no subnet manager on the IB fabric (which may well have been the
case, actually). It's working now, though...
