Function Documentation

cs_block_dist_compute_sizes()

cs_block_dist_info_t cs_block_dist_compute_sizes	(	int	rank_id,
		int	n_ranks,
		int	min_rank_step,
		cs_lnum_t	min_block_size,
		cs_gnum_t	n_g_ents )

Compute block size and rank info for use with a block distribution.

Parameters

[in]	rank_id	id of local rank (ignored in serial mode)
[in]	n_ranks	number of associated ranks
[in]	min_rank_step	minimum rank step between blocks
[in]	min_block_size	minimum number of entities per block
[in]	n_g_ents	total number of associated entities

Returns

block size and range info structure
