xt_redist_collection_static_new()

Xt_redist xt_redist_collection_static_new	(	Xt_redist *	redists,
		int	num_redists,
		const MPI_Aint	src_displacements[num_redists],
		const MPI_Aint	dst_displacements[num_redists],
		MPI_Comm	comm
	)

constructor for a redistribution collection that is comprised of multiple other redistributions

Parameters

[in]	redists	redistributions
[in]	num_redists	number of redistributions
[in]	src_displacements	array of displacements of the source input arrays for the exchange
[in]	dst_displacements	array of displacements of the destination input arrays for the exchange
[in]	comm	MPI communicator

Remarks

all redistributions need to be based on the same MPI communicator

Examples:

test_redist_collection_static.c, and test_redist_collection_static_parallel.c.
