cp_dbcsr_alloc_block_from_nbl()

subroutine, public cp_dbcsr_cp2k_link::cp_dbcsr_alloc_block_from_nbl	(	type(dbcsr_type)	matrix,
		type(neighbor_list_set_p_type), dimension(:), pointer	sab_orb,
		logical, intent(in), optional	desymmetrize
	)

allocate the blocks of a dbcsr based on the neighbor list

Parameters

matrix	the matrix
sab_orb	the corresponding neighbor list
desymmetrize	Allocate all block of a non-symmetric matrix from a symmetric list

Here is the call graph for this function:

cp_dbcsr_to_csr_screening()

subroutine, public cp_dbcsr_cp2k_link::cp_dbcsr_to_csr_screening	(	type(qs_ks_env_type), pointer	ks_env,
		type(dbcsr_type), intent(inout)	csr_sparsity
	)

Apply distance screening to refine sparsity pattern of matrices in CSR format (using eps_pgf_orb). Currently this is used for the external library PEXSI.

Parameters

	ks_env	...
[in,out]	csr_sparsity	DBCSR matrix defining CSR sparsity pattern. This matrix must be initialized and allocated with exactly the same DBCSR sparsity pattern as the DBCSR matrix that is used to create the CSR matrix. It must have symmetric DBCSR format and must not be filtered.
