Greetings,
I'm having trouble getting openmpi 2.1.2 to work when launching a
process from debian 8 on a remote debian 9 host. To keep things simple
in this example, I'm just launching date on the remote host.
deb8host$ mpirun -H deb9host date
[deb8host:01552] [[32763,0],0] ORTE_ERROR_LOG: Error i
More than likely the problem is the difference in hwloc versions - sounds like
the topology to/from xml is different between the two versions, and the older
one doesn’t understand the new one.

Brian,
As Ralph already stated, this is likely a hwloc API issue.
From debian9, you can
lstopo --of xml | ssh debian8 lstopo --if xml -i -
that will likely confirm the API error.
If you are willing to get a bit more details, you can add some printf
in opal_hwloc_unpack (from opal/mca/hwloc/base/
