hwloc_obj_thwloc_get_first_largest_obj_inside_cpuset(hwloc_topology_ttopology,hwloc_const_cpuset_tset)[inline]
Get the first largest object included in the given cpuset set.
Returns
the first object that is included in set and whose parent is not.
NULL if no such object exists.
This is convenient for iterating over all largest objects within a CPU set by doing a loop getting the
first largest object and clearing its CPU set from the remaining CPU set.
inthwloc_get_largest_objs_inside_cpuset(hwloc_topology_ttopology,hwloc_const_cpuset_tset,hwloc_obj_t*restrictobjs,intmax)
Get the set of largest objects covering exactly a given cpuset set.
Returns
the number of objects returned in objs.
-1 if no set of objects may cover that cpuset.
unsignedhwloc_get_nbobjs_inside_cpuset_by_depth(hwloc_topology_ttopology,hwloc_const_cpuset_tset,intdepth)[inline]
Return the number of objects at depth depth included in CPU set set.
Returns
the number of objects.
0 if the depth is invalid.
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if objects at the given depth do not have CPU sets (I/O or Misc objects).
inthwloc_get_nbobjs_inside_cpuset_by_type(hwloc_topology_ttopology,hwloc_const_cpuset_tset,hwloc_obj_type_ttype)[inline]
Return the number of objects of type type included in CPU set set.
Returns
the number of objects.
0 if there are no objects of that type in the topology.
-1 if there are multiple levels of objects of that type, the caller should fallback to
hwloc_get_nbobjs_inside_cpuset_by_depth().
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if objects of the given type do not have CPU sets (I/O objects).
hwloc_obj_thwloc_get_next_obj_inside_cpuset_by_depth(hwloc_topology_ttopology,hwloc_const_cpuset_tset,intdepth,hwloc_obj_tprev)[inline]
Return the next object at depth depth included in CPU set set. The next invokation should pass the
previous return value in prev so as to obtain the next object in set.
Returns
the first object at depth depth included in set if prev is NULL.
the next object at depth depth included in set if prev is not NULL.
NULL if there is no next object.
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if objects at the given depth do not have CPU sets (I/O or Misc objects).
hwloc_obj_thwloc_get_next_obj_inside_cpuset_by_type(hwloc_topology_ttopology,hwloc_const_cpuset_tset,hwloc_obj_type_ttype,hwloc_obj_tprev)[inline]
Return the next object of type type included in CPU set set. The next invokation should pass the previous
return value in prev so as to obtain the next object in set.
Returns
the first object of type type included in set if prev is NULL.
the next object of type type included in set if prev is not NULL.
NULL if there is no next object.
NULL if there is no depth for the given type.
NULL if there are multiple depths for the given type, the caller should fallback to
hwloc_get_next_obj_inside_cpuset_by_depth().
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if objects of the given type do not have CPU sets (I/O or Misc objects).
inthwloc_get_obj_index_inside_cpuset(hwloc_topology_ttopology,hwloc_const_cpuset_tset,hwloc_obj_tobj)[inline]
Return the logical index among the objects included in CPU set set. Consult all objects in the same level
as obj and inside CPU set set in the logical order, and return the index of obj within them. If set
covers the entire topology, this is the logical index of obj. Otherwise, this is similar to a logical
index within the part of the topology defined by CPU set set.
Returns
the logical index among the objects included in the set if any.
-1 if the object is not included in the set.
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if obj does not have CPU sets (I/O objects).
hwloc_obj_thwloc_get_obj_inside_cpuset_by_depth(hwloc_topology_ttopology,hwloc_const_cpuset_tset,intdepth,unsignedidx)[inline]
Return the (logically) idx -th object at depth depth included in CPU set set.
Returns
the object if any, NULL otherwise.
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if objects at the given depth do not have CPU sets (I/O or Misc objects).
hwloc_obj_thwloc_get_obj_inside_cpuset_by_type(hwloc_topology_ttopology,hwloc_const_cpuset_tset,hwloc_obj_type_ttype,unsignedidx)[inline]
Return the idx -th object of type type included in CPU set set.
Returns
the object if any.
NULL if there is no such object.
NULL if there is no depth for given type.
NULL if there are multiple depths for given type, the caller should fallback to
hwloc_get_obj_inside_cpuset_by_depth().
Note
Objects with empty CPU sets are ignored (otherwise they would be considered included in any given
set).
This function cannot work if objects of the given type do not have CPU sets (I/O or Misc objects).
