Functions | |
double | bcscInit (const spmatrix_t *spm, const pastix_order_t *ord, const SolverMatrix *solvmtx, pastix_int_t initAt, pastix_bcsc_t *bcsc) |
Initializes the block csc matrix. More... | |
void | bcscExit (pastix_bcsc_t *bcsc) |
Frees the block csc structure but do not free the bcsc pointer. More... | |
void | bcsc_init_struct (const spmatrix_t *spm, const SolverMatrix *solvmtx, pastix_bcsc_t *bcsc) |
Initializes a block csc. More... | |
void | bcsc_exit_struct (pastix_bcsc_t *bcsc) |
Cleanup the bcsc struct. (symmetric of bcsc_init_struct) More... | |
pastix_int_t | bcsc_init_coltab (const spmatrix_t *spm, const pastix_order_t *ord, const SolverMatrix *solvmtx, pastix_bcsc_t *bcsc) |
Initializes the coltab of a block csc matrix. The coltab corresponds to the number of rows (expended) per column (non expended). If the matrix is distributed in the memory, this function also calls the routines which exchange the amount of data for the communication, store the indexes and values to send and exchange the indexes. More... | |
void | bcsc_restore_coltab (pastix_bcsc_t *bcsc) |
Restores the coltab array when it has been modified to initialize the row and values arrays. More... | |
pastix_int_t * | bcsc_init_col2cblk_shm (const SolverMatrix *solvmtx, const pastix_bcsc_t *bcsc) |
Creates the array which represents the repartition of each column in the block structure. The array size is spm->gNexp where: More... | |
pastix_int_t * | bcsc_init_col2cblk (const SolverMatrix *solvmtx, const pastix_bcsc_t *bcsc, const spmatrix_t *spm) |
Creates the array which represents the repartition of each column in the block structure. This routine calls bcsc_init_col2cblk_shm or bcsc_init_col2cblk_dst according to the way the matrix is stored in the memory. More... | |
void | bcsc_handle_comm_init (const SolverMatrix *solvmtx, pastix_bcsc_t *bcsc) |
Initializes the bcsc_handle_comm_t structure. More... | |
void | bcsc_handle_comm_exit (bcsc_handle_comm_t *bcsc_comm) |
Frees the bcsc_handle_comm pointers. More... | |
