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

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 :-) Jeff On Thu, Sep 13, 2018 at 8:42 AM, Brice Goglin <brice.gog...@inria.fr<mailto:brice.gog...@inria.fr>> wrote: 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 2.0.0rc2, at least because it's old, it has a broken ABI, and it's a RC :) Brice Le 13/09/2018 à 16:12, Jeff Hammond a écrit : 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.
