Detailed Description

 

Function Documentation

 

static hwloc_obj_t hwloc_get_child_covering_cpuset (hwloc_topology_t topology, hwloc_const_cpuset_t set, hwloc_obj_t parent) [inline], [static]

Get the child covering at least CPU set set.

Returns

NULL if no child matches or if set is empty.

Note

This function cannot work if parent does not have a CPU set (I/O or Misc objects).

 

static hwloc_obj_t hwloc_get_next_obj_covering_cpuset_by_depth (hwloc_topology_t topology, hwloc_const_cpuset_t set, int depth, hwloc_obj_t prev) [inline], [static]

Iterate through same-depth objects covering at least CPU set set. If object prev is NULL, return the first object at depth depth covering at least part of CPU set set. The next invokation should pass the previous return value in prev so as to obtain the next object covering at least another part of set.

Note

This function cannot work if objects at the given depth do not have CPU sets (I/O or Misc objects).

 

static hwloc_obj_t hwloc_get_next_obj_covering_cpuset_by_type (hwloc_topology_t topology, hwloc_const_cpuset_t set, hwloc_obj_type_t type, hwloc_obj_t prev) [inline], [static]

Iterate through same-type objects covering at least CPU set set. If object prev is NULL, return the first object of type type covering at least part of CPU set set. The next invokation should pass the previous return value in prev so as to obtain the next object of type type covering at least another part of set.

If there are no or multiple depths for type type, NULL is returned. The caller may fallback to hwloc_get_next_obj_covering_cpuset_by_depth() for each depth.

Note

This function cannot work if objects of the given type do not have CPU sets (I/O or Misc objects).

 

static hwloc_obj_t hwloc_get_obj_covering_cpuset (hwloc_topology_t topology, hwloc_const_cpuset_t set) [inline], [static]

Get the lowest object covering at least CPU set set.

Returns

NULL if no object matches or if set is empty.
