Function Documentation

int hwloc_get_largest_objs_inside_cpuset	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		hwloc_obj_t *restrict	objs,
		int	max
	)

Get the set of largest objects covering exactly a given cpuset set.

Returns:

the number of objects returned in objs.

static inline unsigned hwloc_get_nbobjs_inside_cpuset_by_depth	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		unsigned	depth
	)			[static]

Return the number of objects at depth depth included in CPU set set.

static inline int hwloc_get_nbobjs_inside_cpuset_by_type	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		hwloc_obj_type_t	type
	)			[static]

Return the number of objects of type type included in CPU set set.

If no object for that type exists inside CPU set set, 0 is returned. If there are several levels with objects of that type inside CPU set set, -1 is returned.

static inline hwloc_obj_t hwloc_get_next_obj_inside_cpuset_by_depth	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		unsigned	depth,
		hwloc_obj_t	prev
	)			[static]

Return the next object at depth depth included in CPU set set.

If prev is NULL, return the first object at depth depth included in set. The next invokation should pass the previous return value in prev so as to obtain the next object in set.

static inline hwloc_obj_t hwloc_get_next_obj_inside_cpuset_by_type	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		hwloc_obj_type_t	type,
		hwloc_obj_t	prev
	)			[static]

Return the next object of type type included in CPU set set.

If there are multiple or no depth for given type, return NULL and let the caller fallback to hwloc_get_next_obj_inside_cpuset_by_depth().

static inline hwloc_obj_t hwloc_get_obj_inside_cpuset_by_depth	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		unsigned	depth,
		unsigned	idx
	)			[static]

Return the index -th object at depth depth included in CPU set set.

static inline hwloc_obj_t hwloc_get_obj_inside_cpuset_by_type	(	hwloc_topology_t	topology,
		hwloc_cpuset_t	set,
		hwloc_obj_type_t	type,
		unsigned	idx
	)			[static]

Return the idx -th object of type type included in CPU set set.

If there are multiple or no depth for given type, return NULL and let the caller fallback to hwloc_get_obj_inside_cpuset_by_depth().
