Mapping data relating local CSR indices to local indices of a block-row distributed (BRD) DBCSR matrix, and containing the block structure of the original DBCSR matrix from which the CSR matrix was created.

| integer, | private, | DIMENSION(:), POINTER | :: | csr_to_brd_ind | => | NULL() |
csr_to_brd_ind(csr_ind) gives the location of a matrix element with CSR index csr_ind (location in nzval_local) inside the data_area of the corresponding BRD matrix. If an element of the DBCSR matrix is treated as 0 in the CSR format, the index of this value is not in csr_to_brd_ind. same as csr_to_brd_ind but inverse mapping. If a given DBCSR index dbcsr_ind points to a zero element, then brd_to_csr_ind(dbcsr_ind) is -1. |
| integer, | private, | DIMENSION(:), POINTER | :: | brd_to_csr_ind | => | NULL() |
csr_to_brd_ind(csr_ind) gives the location of a matrix element with CSR index csr_ind (location in nzval_local) inside the data_area of the corresponding BRD matrix. If an element of the DBCSR matrix is treated as 0 in the CSR format, the index of this value is not in csr_to_brd_ind. same as csr_to_brd_ind but inverse mapping. If a given DBCSR index dbcsr_ind points to a zero element, then brd_to_csr_ind(dbcsr_ind) is -1. |
