NAME
       HPL_pdgesv - Solve A x = b.

SYNOPSIS
       #include "hpl.h"

       void  HPL_pdgesv(  HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A
       );

DESCRIPTION
       HPL_pdgesv factors a N+1-by-N matrix using LU  factorization  with  row
       partial	pivoting.   The main algorithm	is the "right looking" variant
       with  or	 without look-ahead.  The  lower  triangular  factor  is  left
       unpivoted  and  the pivots are not returned. The right hand side is the
       N+1 column of the coefficient matrix.

ARGUMENTS
       GRID    (local input)	       HPL_T_grid *
	       On entry,  GRID	points	to the data structure  containing  the
	       process grid information.

       ALGO    (global input)	       HPL_T_palg *
	       On  entry,   ALGO  points to  the data structure containing the
	       algorithmic parameters.

       A       (local input/output)    HPL_T_pmat *
	       On entry, A points to the data structure containing  the	 local
	       array information.
