dbt_test_formats()

subroutine, public dbt_test::dbt_test_formats	(	integer, intent(in)	ndims,
		type(mp_comm_type), intent(in)	mp_comm,
		integer, intent(in)	unit_nr,
		logical, intent(in)	verbose,
		integer, dimension(:), intent(in), optional	blk_size_1,
		integer, dimension(:), intent(in), optional	blk_size_2,
		integer, dimension(:), intent(in), optional	blk_size_3,
		integer, dimension(:), intent(in), optional	blk_size_4,
		integer, dimension(:), intent(in), optional	blk_ind_1,
		integer, dimension(:), intent(in), optional	blk_ind_2,
		integer, dimension(:), intent(in), optional	blk_ind_3,
		integer, dimension(:), intent(in), optional	blk_ind_4
	)

Test equivalence of all tensor formats, using a random distribution.

Parameters

blk_size_i	block sizes along respective dimension
blk_ind_i	index along respective dimension of non-zero blocks
ndims	tensor rank
unit_nr	output unit, needs to be a valid unit number on all mpi ranks
verbose	if .TRUE., print all tensor blocks

dbt_setup_test_tensor()

subroutine, public dbt_test::dbt_setup_test_tensor	(	type(dbt_type), intent(inout)	tensor,
		class(mp_comm_type), intent(in)	mp_comm,
		logical, intent(in)	enumerate,
		integer, dimension(:), intent(in), optional	blk_ind_1,
		integer, dimension(:), intent(in), optional	blk_ind_2,
		integer, dimension(:), intent(in), optional	blk_ind_3,
		integer, dimension(:), intent(in), optional	blk_ind_4
	)

Allocate and fill test tensor - entries are enumerated by their index s.t. they only depend on global properties of the tensor but not on distribution, matrix representation, etc.

Parameters

mp_comm	communicator
blk_ind_i	index along respective dimension of non-zero blocks
