HPL_pdlaprnt(3) HPL Library Functions HPL_pdlaprnt(3)

HPL_pdlaprnt - Print a distributed matrix A.

#include "hpl.h"

void HPL_pdlaprnt( const HPL_T_grid * GRID, const int M, const int N, const int NB, double * A, const int LDA, const int IAROW, const int IACOL, const char * CMATNM );

HPL_pdlaprnt prints to standard error a distributed matrix A. The local pieces of A are sent to the process of coordinates (0,0) in the grid and then printed.

On entry, GRID points to the data structure containing the process grid information.
On entry, M specifies the number of rows of the coefficient matrix A. M must be at least zero.
On entry, N specifies the number of columns of the coefficient matrix A. N must be at least zero.
On entry, NB specifies the blocking factor used to partition and distribute the matrix. NB must be larger than one.
On entry, A points to an array of dimension (LDA,LocQ(N)). This array contains the coefficient matrix to be printed.
On entry, LDA specifies the leading dimension of the array A. LDA must be at least max(1,LocP(M)).
On entry, IAROW specifies the row process coordinate owning the first row of A. IAROW must be larger than or equal to zero and less than NPROW.
On entry, IACOL specifies the column process coordinate owning the first column of A. IACOL must be larger than or equal to zero and less than NPCOL.
On entry, CMATNM is the name of the matrix to be printed.
