Function Documentation

delete_map()

void delete_map

(

t_map *

map

)

Clean memory of a t_map structure.

Free all the memory of a t_map structure

Parameters

[in]

map

pointer to t_map structure

extend_map_3d()

t_map* extend_map_3d	(	t_map *	map2d,
		int	nlevels
	)

Create a new t_map structure for 3D decomposition.

Create a map given an existing map based on 2D decomposition

Parameters

[in]	map2d	pointer to t_map structure based on 2D decomposition
[in]	nlevels	number of vertical levels of the domain

Returns

t_map structure

new_map()

		t_idxlist *	dst_idxlist,
		int	stride,
		MPI_Comm	comm
	)

Create a new t_map structure.

[in]	dst_idxlist	pointer to destination index list
[in]	stride	bucket stride
[in]	comm	MPI communicator containing all the MPI procs involved in the exchange

Returns

t_map structure
