xt_ut_init()

void xt_ut_init	(	int	decomp_size,
		int	comm_tmpl_size,
		int	comm_size,
		int	debug_lvl,
		int	mode,
		int	debug_unit
	)

Initialization of support data for unitrans (start sizes of allocated data). We use the unitrans names. Unlike unitrans, the allocated data can grow.

Parameters

[in]	decomp_size	number of decompositions
[in]	comm_tmpl_size	number of communication templates
[in]	comm_size	number of transpositions
[in]	debug_lvl	debug level
[in]	mode	default communication mode
[in]	debug_unit	fortran file unit for debug output (not used)

xt_ut_init_decomposition_1d()

int xt_ut_init_decomposition_1d	(	Xt_int *	idx_vec,
		int	idx_vec_n
	)

creates new decomposition and returns access handle

Parameters

[in]	idx_vec	local index vector
[in]	idx_vec_n	size of idx_vec

Returns

returns handle

xt_ut_init_oneway_transposition_template()

int xt_ut_init_oneway_transposition_template	(	int	decomp_handle_in,
		int	decomp_handle_out,
		int	mpi_world,
		int	icheck_unique
	)

creates new unitrans compatible oneway transposition decomposition and returns access handle

Parameters

[in]	decomp_handle_in	access handle for input decomposition
[in]	decomp_handle_out	access handle for output decomposition
[in]	mpi_world	mpi communicator
[in]	icheck_unique	enable/disbale check of uniqueness

Returns

returns handle
