Function Documentation

xt_redist_collection_custom_new()

Xt_redist xt_redist_collection_custom_new	(	Xt_redist *	redists,
		int	num_redists,
		int	cache_size,
		MPI_Comm	comm,
		Xt_config	config
	)

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

Parameters

[in]	redists	redistributions
[in]	num_redists	number of redistributions
[in]	cache_size	number of cached datatypes required for different input array displacements n = -1 => default cache size n = 0 => no cache n > 0 => cache size = n
[in]	comm	MPI communicator
[in]	config	custom configuration object

Remarks

all redistributions need to be based on the same MPI communicator
