Detailed Description

Function Documentation

hwloc_distances_obj_index()

static int hwloc_distances_obj_index ( struct hwloc_distances_s *  distances, hwloc_obj_t  obj  )

inlinestatic

Find the index of an object in a distances structure.

Returns

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

hwloc_distances_obj_pair_values()

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  )

inlinestatic

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.
