+Subject: [PATCH] Fix Processing Unit calculation for non-NUMA machine
+
+For hwloc without commit ba7d4976d38f, function
+
+hwloc_get_nbobjs_by_type(topology, HWLOC_OBJ_NUMANODE)
+
+return zero instead of one when no NUMA node exists.
+
+This patch fixes a floating point exception issue for non-NUMA
+machine.
