the user is responsible for free the memory of the vertex_to_cell array
the user has to make sure that the array num_cells_per_vertex is at least of size "count"

char const * grid_name,
size_t * vertices,
size_t count,
size_t ** neigh_vertices,
int * num_neighs_per_vertex,
struct yac_interp_field field )

Determines all non-masked neighour vertices for the selected vertices

Parameters
[in]grid_pairdistributed grid pair
[in]grid_namegrid name of the grid on which this routine is supposed to work on
[in]verticeslocal ids of selected vertices
[in]countnumber of entries in vertices
[out]neigh_verticesneighbour vertices
[out]num_neighs_per_vertexnumber of neighbours per vertex
[in]fieldif the provided field contains a mask for corners, it will be used
Remarks
the user has to ensure that num_neighs_per_vertex is allocated big enough
the user is responsible for freeing memory associated to neigh_vertices

◆ yac_dist_grid_pair_relocate_point_pairs()

void yac_dist_grid_pair_relocate_point_pairs ( struct yac_dist_grid_pair * grid_pair,
int a_is_ref,
int to_dist_owner,
char const * grid_name_a,
size_t ** points_a,
enum yac_location location_a,
char const * grid_name_b,
size_t ** points_b,
enum yac_location location_b,
double ** weights,
size_t * count )

Each point in a distributed grid has a unique owner rank.
This routine relocates point pairs of two grids. If (a_is_ref != 0), this routine will relocate the point pairs such that each process only has pairs with points_a being owned by the respective process.

Parameters
[in]grid_pairdistributed grid pair
[in]a_is_refdetermines whether points_a or points_b are used as the sorting reference
[in]to_dist_ownerdetermines whether the sorting is based on the dist or orig owner of the respective points
[in]grid_name_agrid name for the a-part of point pairs
[in,out]points_alocal ids of the a-part of the point pairs
[in]location_alocation of the a-part of the point pairs
[in]grid_name_bgrid name for the b-part of point pairs
[in,out]points_blocal ids of the b-part of the point pairs
[in]location_blocation of the b-part of the point pairs
[in,out]weightsweights for all point pairs
[in,out]countnumber of point pairs before and after this routine
