Yes, I think that test is valid. 1.10.0 is a good version to test.
Ralph: it all looks good to me, but that message is coming from ORTE. Can you
have a look?
Sent from my phone. No type good.

So, unless you turned off the default binding -- to socket? check the
mpirun man page -- it worked, but the "numa" level failed. I don't know
if that level has to exist, a
I think Dave has probably hit the problem - that node may well not have a
“numa” object. You also might check that node “leo” has libnuma on it

I have a shared memory system, I run on the machine I build the stuff.

He's building and running on a single server (leo). From the configure output,
all the numa libs and headers are available on this leo server.

I honestly have no ideas…best I can see, it looks like hwloc feels that it
cannot perform that operation and returns an error.

Brice -- I know this started on the hwloc list and then bounced over here, but
we're running out of ideas.
Got any clue what is happening here? From the OMPI config logs that Fabian
sent, it looks like hwloc built with libnuma support properly...?

Oh, that's an interesting idea: perhaps the "bind to numa" is failing -- but
perhaps "bind to socket" would work.
Can you try:
/opt/openmpi-1.10.0-gcc/bin/mpiexec -bind-to numa -n 4 hostname
and
/opt/openmpi-1.10.0-gcc/bin/mpiexec -bind-to socket -n 4 hostname
