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.
