Functions/Subroutines | |
| subroutine | validate (matrix) |
| Dummy for when DBM_VALIDATE_AGAINST_DBCSR is not defined. | |
| subroutine, public | dbm_create_from_template (matrix, name, template) |
| Creates a new matrix from given template, reusing dist and row/col_block_sizes. | |
| subroutine, public | dbm_create (matrix, name, dist, row_block_sizes, col_block_sizes) |
| Creates a new matrix. | |
| subroutine, public | dbm_finalize (matrix) |
| Needed to be called for DBCSR after blocks where inserted. For DBM it's a no-opt. | |
| subroutine, public | dbm_release (matrix) |
| Releases a matrix and all its ressources. | |
| subroutine, public | dbm_copy (matrix_a, matrix_b) |
| Copies content of matrix_b into matrix_a. Matrices must have the same row/col block sizes and distribution. | |
| subroutine, public | dbm_redistribute (matrix, redist) |
| Copies content of matrix_b into matrix_a. Matrices may have different distributions. | |
| subroutine, public | dbm_get_block_p (matrix, row, col, block, row_size, col_size) |
| Looks up a block from given matrics. This routine is thread-safe. If the block is not found then a null pointer is returned. | |
| subroutine, public | dbm_put_block (matrix, row, col, block, summation) |
| Adds a block to given matrix. This routine is thread-safe. If block already exist then it gets overwritten (or summed). | |

| Remove all blocks from given matrix, but does not release the underlying memory. | |
