With HWLOC_COMPONENTS=no_os, MPICH is now working fine but all tests now
fail with Open-MPI (see below). I know how to resolve this, but am noting
it for the benefit of others.

We will upgrade the hwloc submodule used in MPICH asap. IIRC, we have supressed
hwloc warnings as well. I will double check this.

All of the job failures have this warning so I am inclined to think they
are related. I don't know what I should expect from lstopo on inside of
AWS, but I guess I'll try it.
I was using the hwloc shipped with the mpich-3.3b1. Talk to the MPICH team
if you want them to upgrade :-)

This is actually just a warning. Usually it causes the topology to be
wrong (like a missing object), but it shouldn't prevent the program from
working. Are you sure your programs are failing because of hwloc? Do you
have a way to run lstopo on that node?
By the way, you shouldn't use hwloc
I am running ARMCI-MPI over MPICH in a Travis CI Linux instance and
topology is causing it to fail. I do not care about topology in a
virtualized environment. How do I fix this?
