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.
- 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.
