 Get the statistics of the supernodes.

Functions

void superlu_abort_and_exit (char *msg)
 Global statistics variale.
void set_default_options (superlu_options_t *options)
 Set the default values for the options argument.
void print_options (superlu_options_t *options)
 Print the options setting.
void Destroy_SuperMatrix_Store (SuperMatrix *A)
 Deallocate the structure pointing to the actual storage of the matrix.
void Destroy_CompCol_Matrix (SuperMatrix *A)
void Destroy_CompRow_Matrix (SuperMatrix *A)
void Destroy_SuperNode_Matrix (SuperMatrix *A)
void Destroy_CompCol_Permuted (SuperMatrix *A)
 A is of type Stype==NCP.
void Destroy_Dense_Matrix (SuperMatrix *A)
 A is of type Stype==DN.
void resetrep_col (const int nseg, const int *segrep, int *repfnz)
 Reset repfnz[] for the current column.
void countnz (const int n, int *xprune, int *nnzL, int *nnzU, GlobalLU_t *Glu)
 Count the total number of nonzeros in factors L and U, and in the symmetrically reduced L.
void fixupL (const int n, const int *perm_r, GlobalLU_t *Glu)
 Fix up the data storage lsub for L-subscripts. It removes the subscript sets for structural pruning, and applies permuation to the remaining subscripts.
void print_panel_seg (int n, int w, int jcol, int nseg, int *segrep, int *repfnz)
 Diagnostic print of segment info after panel_dfs().
void StatInit (SuperLUStat_t *stat)
void StatPrint (SuperLUStat_t *stat)
void StatFree (SuperLUStat_t *stat)
flops_t LUFactFlops (SuperLUStat_t *stat)
flops_t LUSolveFlops (SuperLUStat_t *stat)
void ifill (int *a, int alen, int ival)
 Fills an integer array with a given value.
void super_stats (int nsuper, int *xsup)
float SpaSize (int n, int np, float sum_npw)
float DenseSize (int n, float sum_nw)
void check_repfnz (int n, int w, int jcol, int *repfnz)
 Check whether repfnz[] == EMPTY after reset.
void PrintSumm (char *type, int nfail, int nrun, int nerrs)
 Print a summary of the testing results.
int print_int_vec (char *what, int n, int *vec)
