Functions

static inline int
 
hwloc_get_type_or_below_depth (hwloc_topology_t topology, hwloc_obj_type_t type)
 Returns the depth of objects of type type or below.
static inline int
 
hwloc_get_type_or_above_depth (hwloc_topology_t topology, hwloc_obj_type_t type)
 Returns the depth of objects of type type or above.

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 socket has fewer caches than its peers.


Function Documentation

static inline int hwloc_get_type_or_above_depth ( hwloc_topology_t  topology,
hwloc_obj_type_t  type 
) [static]

Returns the depth of objects of type type or above.

If no object of this type is present on the underlying architecture, the function returns the depth of the first "present" object typically containing type.

static inline int hwloc_get_type_or_below_depth ( hwloc_topology_t  topology,
hwloc_obj_type_t  type 
) [static]

Returns the depth of objects of type type or below.

If no object of this type is present on the underlying architecture, the function returns the depth of the first "present" object typically found inside type.
