Here is the caller graph for this function:

yac_duplicate_stencils()

void yac_duplicate_stencils	(	struct yac_interp_weights *	weights,
		struct yac_basic_grid *	tgt_grid,
		yac_int *	tgt_orig_global_id,
		size_t *	tgt_duplicated_idx,
		size_t	nbr_duplicated,
		enum yac_location	location
	)

Duplicates stencils for specified target points in a yac_interp_weights data structure.

Parameters

[in,out]	weights	weights data structure
[in]	tgt_grid	target grid
[in]	tgt_orig_global_id	global ids of target points, whose interpolation stencils are to be duplicated
[in]	tgt_duplicated_idx	local ids of target points, who are to interpolated using the duplicated stencils
[in]	nbr_duplicated	number of stencils that are to be duplicated
[in]	location	location of target points

Remarks

this operation is collective for all processes involved in the creation of the weights data structure
