It was fixed by Galen for 1.2.
Ah -- I forgot to look at closed tickets. I think we broke it again;
it certainly fails on the trunk (perhaps related to what Gleb
found?). I did not test 1.2.
There is a FAQ entry also about this http://www.open-mpi.org/faq/?
category=openfabrics#ofa-port-wireup
That's what it *should* be doing, but I wonder if that's what it
*actually* is doing.
So it has been a while but we tested this on our local cluster with
differing number of ports and it worked, but I was doing simple ping-
pongs.
If both sides try to open a connection at the same time however,
badness can occur, from my understanding of this.
