Detailed Description

Function Documentation

◆ hwloc_distances_obj_index()

static int hwloc_distances_obj_index ( struct hwloc_distances_s distances,
hwloc_obj_t  obj 

Find the index of an object in a distances structure.

-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 

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.

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