Oops, you're right! Thanks. I thought what I'm using elsewhere was built from the same srpm, but the rpm on the KNL box doesn't actually require libnuma. After a rebuild, it's OK and I'm suitably embarrassed. By the way, is it expected that binding will be slow on it? hwloc-bind is ~10 times slower (~1s) than on two-socket sandybridge, and ~3 times slower than on a 128-core, 16-socket system. _______________________________________________ hwloc-users mailing list hwloc-users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/hwloc-users
