.SH DESCRIPTION |
| 29 |
\fB\&HPL_pdlaprnt\fR |
| 30 |
prints to standard error a distributed matrix A. The |
| 31 |
local pieces of A are sent to the process of coordinates (0,0) in |
| 32 |
the grid and then printed. |
| 33 |
.SH ARGUMENTS |
| 34 |
.TP 8 |
| 35 |
GRID (local input) const HPL_T_grid * |
| 36 |
On entry, GRID points to the data structure containing the |
| 37 |
process grid information. |
| 38 |
.TP 8 |
| 39 |
M (global input) const int |
| 40 |
On entry, M specifies the number of rows of the coefficient |
| 41 |
matrix A. M must be at least zero. |
| 42 |
.TP 8 |
| 43 |
N (global input) const int |
| 44 |
On entry, N specifies the number of columns of the |
| 45 |
coefficient matrix A. N must be at least zero. |
| 46 |
.TP 8 |
| 47 |
NB (global input) const int |
| 48 |
On entry, NB specifies the blocking factor used to partition |
| 49 |
and distribute the matrix. NB must be larger than one. |
| 50 |
.TP 8 |
| 51 |
A (local input) double * |
| 52 |
On entry, A points to an array of dimension (LDA,LocQ(N)). |
| 53 |
This array contains the coefficient matrix to be printed. |
| 54 |
.TP 8 |
| 55 |
LDA (local input) const int |
| 56 |
On entry, LDA specifies the leading dimension of the array A. |
| 57 |
LDA must be at least max(1,LocP(M)). |
| 58 |
.TP 8 |
| 59 |
IAROW (global input) const int |
| 60 |
On entry, IAROW specifies the row process coordinate owning |
| 61 |
the first row of A. IAROW must be larger than or equal to |
| 62 |
zero and less than NPROW. |
| 63 |
.TP 8 |
| 64 |
IACOL (global input) const int |
| 65 |
On entry, IACOL specifies the column process coordinate |
| 66 |
owning the first column of A. IACOL must be larger than or |
| 67 |
equal to zero and less than NPCOL. |
| 68 |
.TP 8 |
| 69 |
CMATNM (global input) const char * |
| 70 |
On entry, CMATNM is the name of the matrix to be printed. |
