Hello Can you send more details about the incompatibility between hwloc old and recent versions? Maybe there's a workaround there. hwloc is supposed to maintain compatibility but we've seen cases where XML export/import doesn't work because the old version exports buggy XMLs that the recent version considers as invalid. Do you get hwloc warnings or error messages? Brice
