◆ yac_interp_weights_get_interp_count()
| size_t yac_interp_weights_get_interp_count | ( | struct yac_interp_weights * | weights | ) |
returns the count of all target for which the weights contain a stencil
- Parameters
-
[in] weights interpolation weights
- Returns
- count of all targets in weights with a stencil

◆ yac_interp_weights_get_interp_tgt()
| yac_int * yac_interp_weights_get_interp_tgt | ( | struct yac_interp_weights * | weights | ) |
returns the global ids of all targets for which the weights contain a stencil
- Parameters
-
[in] weights interpolation weights
- Returns
- global ids of all targets in weights with a stencil

| double | frac_mask_fallback_value, | ||
| double | scaling_factor, | ||
| double | scaling_summand | ||
| ) |
generates an interpolation from interpolation weights
- Parameters
-
[in] weights interpolation weights [in] reorder determines at which processes the weights are to be applied [in] collection_size collection size [in] frac_mask_fallback_value fallback value for dynamic fractional masking [in] scaling_factor scaling factor [in] scaling_summand scaling summand
- Returns
- interpolation
- Remarks
- if frac_mask_fallback_value != YAC_FRAC_MASK_NO_VALUE, dynamic fractional masking will be used
-
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:
y = scaling_factor * x + scaling_summand

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
- 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.
