Functions |
void * | sexpand (int *prev_len,MemType type,int len_to_copy,int keep_prev,GlobalLU_t *Glu) |
| Expand the existing storage to accommodate more fill-ins.
|
int | sLUWorkInit (int m, int n, int panel_size, int **iworkptr, float **dworkptr, LU_space_t MemModel) |
| Allocate known working storage. Returns 0 if success, otherwise returns the number of bytes allocated so far when failure occurred.
|
void | copy_mem_float (int, void *, void *) |
void | sStackCompress (GlobalLU_t *Glu) |
| Compress the work[] array to remove fragmentation.
|
void | sSetupSpace (void *work, int lwork, LU_space_t *MemModel) |
| Setup the memory model to be used for factorization.
|
void * | suser_malloc (int, int) |
void | suser_free (int, int) |
void | copy_mem_int (int, void *, void *) |
void | user_bcopy (char *, char *, int) |

int | sLUMemInit (fact_t fact, void *work, int lwork, int m, int n, int annz, int panel_size, SuperMatrix *L, SuperMatrix *U, GlobalLU_t *Glu, int **iwork, float **dwork) |
| Memory-related.
|
void | sSetRWork (int m, int panel_size, float *dworkptr, float **dense, float **tempv) |
| Set up pointers for real working arrays.
|
void | sLUWorkFree (int *iwork, float *dwork, GlobalLU_t *Glu) |
| Free the working storage used by factor routines.
|
int | sLUMemXpand (int jcol, int next, MemType mem_type, int *maxlen, GlobalLU_t *Glu) |
| Expand the data structures for L and U during the factorization.
|
void | sallocateA (int n, int nnz, float **a, int **asub, int **xa) |
| Allocate storage for original matrix A.
|
float * | floatMalloc (int n) |
float * | floatCalloc (int n) |
int | smemory_usage (const int nzlmax, const int nzumax, const int nzlumax, const int n) |
