Detailed Description
Be sure to see the figure in Terms and Definitions that shows a
complete topology tree, including depths, child/sibling/cousin
relationships, and an example of an asymmetric topology where one
package has fewer caches than its peers.
Function Documentation
static hwloc_obj_t hwloc_get_ancestor_obj_by_depth (hwloc_topology_t
topology, unsigned depth, hwloc_obj_t obj) [inline], [static]
Returns the ancestor object of obj at depth depth.
static hwloc_obj_t hwloc_get_ancestor_obj_by_type (hwloc_topology_t
topology, hwloc_obj_type_t type, hwloc_obj_t obj) [inline], [static]
Returns the ancestor object of obj with type type.
static hwloc_obj_t hwloc_get_common_ancestor_obj (hwloc_topology_t
topology, hwloc_obj_t obj1, hwloc_obj_t obj2) [inline], [static]
Returns the common parent object to objects obj1 and obj2.
static hwloc_obj_t hwloc_get_next_child (hwloc_topology_t topology,
hwloc_obj_t parent, hwloc_obj_t prev) [inline], [static]
Return the next child. If prev is NULL, return the first child.
static int hwloc_obj_is_in_subtree (hwloc_topology_t topology, hwloc_obj_t
obj, hwloc_obj_t subtree_root) [inline], [static]
Returns true if obj is inside the subtree beginning with ancestor
object subtree_root.
Note:
This function assumes that both obj and subtree_root have a cpuset.
