Re: [hwloc-users] Travis CI unit tests failing with HW "operating system" error

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. -- All nodes which are allocated for this job

We will upgrade the hwloc submodule used in MPICH asap. IIRC, we have supressed hwloc warnings as well. I will double check this. Kavitha On Sep 14, 2018, at 12:36 AM, Brice Goglin mailto:brice.gog...@inria.fr>> wrote: If lstopo fails there, run "hwloc-gather-topology foo" and send

If lstopo fails there, run "hwloc-gather-topology foo" and send foo.tar.bz2 As a workaround for ARMCI, you may try setting HWLOC_COMPONENTS=no_os,stop in the environment so that hwloc behaves as if the operating system had no topology support. Brice Le 14/09/2018 à 06:11, Jeff Hammond a écrit

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 :-) Jeff On

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? * hwloc 2.0.0rc2-git has encountered
