template<typename T, typename W>

T ALL::Functions::borderShift1d	(	const int	remote_rank,
		const int	local_coord,
		const int	global_dim,
		const W	local_work,
		const W	remote_work,
		const T	local_size,
		const T	remote_size,
		const T	gamma,
		const T	minSize )

function to compute the one-dimensional shift of the border between the local process and the process indicated by neighbor_rank

Template Parameters

T	data type for vertices and related data
W	data type for work and related data

Parameters

[in]	remote_rank	the MPI rank of the neighbors the border is shared with
[in]	local_coord	the cartesian coordinate of the local domain in the process grid in the direction of the border shift
[in]	global_dim	the dimension of the process grid in the direction of the border shift
[in]	local_work	the work on the local process
[in]	remote_work	the work on the neighboring process
[in]	local_size	the size of the local domain in the dimension of the border shift
[in]	remote_size	the size of the neighbor domain in the dimension of the border shift
[in]	gamma	the correction value for the shift, needed to regulate the width of the shift, e.g. to avoid borders shifts where next-neighbor borders are crossed by one another
[in]	minSize	optional minimum size of the domain in the dimension of the border shift

Returns

the shift of the border in relation to the local domain
