I'm somewhat confused by binding on Knights Landing -- which is probably a feature.
I'm looking at a KNL box configured as "Cluster Mode: SNC4 Memory Mode: Cache" with hwloc 1.11.4; I've read the KNL hwloc FAQ entries. I ran openmpi and it reported failure to bind memory (but binding to cores was OK). So I tried hwloc-bind --membind and that seems to fail with no matter what I do, reporting hwloc_set_membind 0x00000002 (policy 2 flags 0) failed (errno 38 Function not implemented) Is that expected, and is there a recommendation on how to do binding in that configuration with things that use hwloc? I'm particularly interested in OMPI, but I guess this is a better place to ask. Thanks. _______________________________________________ hwloc-users mailing list hwloc-users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/hwloc-users
