Function Documentation

cs_grid_get_merge_options()

void cs_grid_get_merge_options	(	int *	rank_stride,
		int *	cells_mean_threshold,
		cs_gnum_t *	cells_glob_threshold,
		int *	min_ranks
	)

Query the global multigrid parameters for parallel grid merging.

Parameters

[out]	rank_stride	number of ranks over which merging takes place, or NULL
[out]	cells_mean_threshold	mean number of cells under which merging should be applied, or NULL
[out]	cells_glob_threshold	global number of cells under which merging should be applied, or NULL
[out]	min_ranks	number of active ranks under which no merging takes place, or NULL

cs_grid_log_merge_options()

void cs_grid_log_merge_options

(

void

)

Log the current settings for multigrid parallel merging.

cs_grid_set_matrix_tuning()

void cs_grid_set_matrix_tuning	(	cs_matrix_fill_type_t	fill_type,
		int	max_level
	)

Set matrix tuning behavior for multigrid coarse meshes.

The finest mesh (level 0) is handled by the default tuning options, so only coarser meshes are considered here.

Parameters

[in]	fill_type	associated matrix fill type
[in]	max_level	maximum level for which tuning is active

cs_grid_set_matrix_variant()

void cs_grid_set_matrix_variant	(	cs_matrix_fill_type_t	fill_type,
		int	level,
		const cs_matrix_variant_t *	mv
	)

Force matrix variant selection for multigrid coarse meshes.

The finest mesh (level 0) is handled by the default tuning options, so only coarser meshes are considered here.

Parameters

[in]	fill_type	associated matrix fill type
[in]	level	level for which variant is assiged
[in]	mv	matrix variant to assign (NULL to unassign)

cs_grid_set_merge_options()

void cs_grid_set_merge_options	(	int	rank_stride,
		int	cells_mean_threshold,
		cs_gnum_t	cells_glob_threshold,
		int	min_ranks
	)

Set global multigrid parameters for parallel grid merging behavior.

Parameters

[in]	rank_stride	number of ranks over which merging takes place
[in]	cells_mean_threshold	mean number of cells under which merging should be applied
[in]	cells_glob_threshold	global number of cells under which merging should be applied
[in]	min_ranks	number of active ranks under which no merging takes place
