11 void HPL_pdlaprnt( const HPL_T_grid * GRID, const int M, const int N,
12 const int NB, double * A, const int LDA, const int IAROW, const int
13 IACOL, const char * CMATNM );
14
16 HPL_pdlaprnt prints to standard error a distributed matrix A. The
17 local pieces of A are sent to the process of coordinates (0,0) in
18 the grid and then printed.
19
21 GRID (local input) const HPL_T_grid *
22 On entry, GRID points to the data structure containing the
23 process grid information.
24
25 M (global input) const int
26 On entry, M specifies the number of rows of the coefficient
27 matrix A. M must be at least zero.
28
29 N (global input) const int
30 On entry, N specifies the number of columns of the
31 coefficient matrix A. N must be at least zero.
32
33 NB (global input) const int
34 On entry, NB specifies the blocking factor used to partition
35 and distribute the matrix. NB must be larger than one.
36
37 A (local input) double *
38 On entry, A points to an array of dimension (LDA,LocQ(N)).
39 This array contains the coefficient matrix to be printed.
40
41 LDA (local input) const int
42 On entry, LDA specifies the leading dimension of the array A.
43 LDA must be at least max(1,LocP(M)).
44
45 IAROW (global input) const int
46 On entry, IAROW specifies the row process coordinate owning
47 the first row of A. IAROW must be larger than or equal to
48 zero and less than NPROW.
49
50 IACOL (global input) const int
51 On entry, IACOL specifies the column process coordinate
52 owning the first column of A. IACOL must be larger than or
53 equal to zero and less than NPCOL.
54
55 CMATNM (global input) const char *
56 On entry, CMATNM is the name of the matrix to be printed.
