Description
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.
Arguments
GRID (local input) const HPL_T_grid *
On entry, GRID points to the data structure containing the
process grid information.
M (global input) const int
On entry, M specifies the number of rows of the coefficient
matrix A. M must be at least zero.
N (global input) const int
On entry, N specifies the number of columns of the
coefficient matrix A. N must be at least zero.
NB (global input) const int
On entry, NB specifies the blocking factor used to partition
and distribute the matrix. NB must be larger than one.
A (local input) double *
On entry, A points to an array of dimension (LDA,LocQ(N)).
This array contains the coefficient matrix to be printed.
LDA (local input) const int
On entry, LDA specifies the leading dimension of the array A.
LDA must be at least max(1,LocP(M)).
IAROW (global input) const int
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.
IACOL (global input) const int
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.
CMATNM (global input) const char *
On entry, CMATNM is the name of the matrix to be printed.
