int AL_Exchange	(	void *	vbuf,
		int	sz_ptr
	)

Fill the ghost boundaries

Parameters

[in]	vbuf	pointer to buffer
[in]	sz_ptr	integer pointer to the distributed array descriptor

int AL_Exchange_periods	(	void *	vbuf,
		int *	periods,
		int	sz_ptr
	)

Same as AL_Exchange, but exchanges periodic boundaries at physical domain in the dim direction only if periods[dim] = 1. If a dimension is not periodic and periods[dim] = 1 nothing changes.

Parameters

[in]	vbuf	pointer to buffer
[in]	periods
[in]	sz_ptr	integer pointer to the distributed array descriptor
