They are optional, which means we cannot assume them for portability reasons. FWIW, we have made the rest of mpich stack-usage clean. -- Pavan _______________________________________________ hwloc-users mailing list hwloc-users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/hwloc-users
