Distributed SuperLU deﬁned data structures

In the following deﬁnitions of data structures, "int_t" is "int" for

SuperLU_DIST routines and is "long long" for SuperLU_DIST8 routines.

1. Data structure only for double precision:

/***************************************************/

/* Definition of structure: LocalLU_t */

/***************************************************/

#define NBUFFERS 5

typedef struct {

int_t **Lrowind_bc_ptr;

double **Lnzval_bc_ptr;

int_t **Ufstnz_br_ptr;

double **Unzval_br_ptr;

int_t *Lsub_buf_2[2];

double *Lval_buf_2[2];

int_t *Usub_buf;

double *Uval_buf;

double *ujrow;

int_t bufmax[NBUFFERS];

int_t *ToRecv;
