Function Documentation

cs_block_to_part_global_to_local()

void cs_block_to_part_global_to_local	(	cs_lnum_t	n_ents,
		cs_lnum_t	base,
		cs_lnum_t	global_list_size,
		bool	global_list_is_sorted,
		const cs_gnum_t	global_list[],
		const cs_gnum_t	global_number[],
		cs_lnum_t	local_number[] )

Determine local references from references to global numbers.

This is based on finding the local id of a given global number using a binary search.

Global numbers use a 1 to n numbering, while local numbers use a 0+base to n-1+base numbering. If an entity's global number does not appear in the global list, base-1 is assigned for that entity's local list.

If list contains duplicate values, any local id having a multiple global number (i.e not necessarily the smallest one) may be assigned to the corresponding local_number[] entry.

Parameters

[in]	n_ents	number of entities
[in]	base	base numbering (typically 0 or 1)
[in]	global_list_size	size of global entity list
[in]	global_list_is_sorted	true if global entity list is guaranteed to be sorted
[in]	global_list	global entity list
[in]	global_number	entity global numbers (size: n_ents)
[out]	local_number	entity local numbers (size: n_ents)
