all target field values, whose source points are not masked by the fractional mask, that receive a interpolation value, which is not a fixed value will by scaled by the following formula:

[out]	interpolation_exchange	interpolation exchange structure
[out]	interp_weights_data	interpolation data required to compute local target points from the received source points

Remarks

if yaxt_exchanger_name == NULL, the default exchanger will be used

adds targets whose stencil is the weighted sum of the copies of existing stencils

Parameters

[in]	weights	interpolation weights
[in]	tgts	targets that get the weightes sum
[in]	num_stencils_per_tgt	number of stencils per target
[in]	stencil_indices	indices of the stencils to be copied
[in]	stencil_ranks	ranks of the processs owning the respective stencil
[in]	w	weights

		char const *	tgt_grid_name,
		size_t	src_grid_size,
		size_t	tgt_grid_size,
		enum yac_weight_file_on_existing	on_existing )

writes interpolation weights to file

Parameters

[in]	weights	interpolation weights
[in]	filename	file name
[in]	src_grid_name	name of the source grid
[in]	tgt_grid_name	name of the target grid
[in]	src_grid_size	global size of the source grid
[in]	tgt_grid_size	global size of the target grid
[in]	on_existing	specifies how YAC is supposed to handle the case of an already existing file with the same name

Remarks

this call is collective

Global grid size argument can be either the global grid size or zero. If a valid global grid size was provided by at least one process, it will be added as a dimension to the weight file.

static

adds new data to a source field exchange messages

Parameters

[in,out]	src_field_exchange_data	source field exchange messages
[in]	num_src_fields	number of source fields
[in]	comm	MPI communicator
[in]	send_msg_sizes	array with send message sizes ([comm_size][num_src_fields])
[in]	send_pos	positions to be sent
[in]	recv_msg_sizes	array with receive messages sizes ([comm_size][num_src_fields])
[in]	recv_pos	positions to be received
[in]	recv_offsets	offsets to be added to receive messages ([num_src_fields])

Remarks

The send data is extracted from the field data provided by the user.

The receive data is written to a buffer, which may already contain data. Hence the receive positions have to be offset by the amount of data already in the buffer.
