I’m wondering if it is also possible that the error message is simply printing
that ID incorrectly. Looking at the code, it appears that we do perform the
network byte translation correctly when we setup the data for transmission
between the processes. However, I don’t see that translation being
This is not a heterogeneous run-time issue -- it's the issue that Nathan cited:
that OMPI detected different receive queue setups on different machines.
As the error message states; the openib BTL simply cannot handle when different
MPI processes specific different receive queue specifications.

Yes.

This probably isn’t very helpful, but fwiw: we added an automatic “fingerprint”
capability in the later OMPI versions just to detect things like this. If the
fingerprint of a backend node doesn’t match the head node, we automatically
assume hetero-nodes. It isn’t foolproof, but it would have pic

how was this configured? We aren’t seeing this problem elsewhere.

Hmm, a master-ism that made it into 1.10. Wasn't caught by Jenkins. Will
fix now.

Just to be sure. How are you measuring the memory usage? If you are
using /proc/meminfo are you subracting out the Cached memory usage?

We are experiencing a problem when debugging the message queues:
