hwlocality_distances_consult - Helpers for consulting distance matrices


static int hwloc_distances_obj_index (struct hwloc_distances_s *distances, hwloc_obj_t obj)
static int hwloc_distances_obj_pair_values (struct hwloc_distances_s *distances, hwloc_obj_t obj1, hwloc_obj_t obj2, hwloc_uint64_t *value1to2, hwloc_uint64_t *value2to1)

Find the index of an object in a distances structure.

Returns

-1 if object obj is not involved in structure distances.

Find the values between two objects in a distance matrices. The distance from obj1 to obj2 is stored in the value pointed by value1to2 and reciprocally.

Returns

-1 if object obj1 or obj2 is not involved in structure distances.
