Hi I have a question on topology query. The hwloc 2.0.0 documentation states that "Additionally it may assemble the topologies of multiple machines into a single one so as to let applications consult the topology of an entire fabric or cluster at once.”. Since “system” object type has been

Hello folks, The function hwloc_get_type_or_above_depth() is supposed to return the depth of objects of type “type" or above. It internally calls hwloc_get_type_depth which returns virtual depths to NUMA, IO and misc objects. In order to retrieve the actual depth of these objects, one needs to

[hwloc-users] Netloc integration with hwloc

Hi I need some info on the status of netloc integration with hwloc. I see the include/netloc.h header is almost empty in hwloc 2.0 and lots of functionality missing compared to the previous standalone netloc release, even in private/netloc.h. Am I missing something here? Thanks Kavitha

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
