Purpose
=======

The driver program PZDRIVE.

This example illustrates how to use PZGSSVX with the full
(default) options to solve a linear system.

Five basic steps are required:
  1. Initialize the MPI environment and the SuperLU process grid
  2. Set up the input matrix and the right-hand side
  3. Set the options argument
  4. Call pzgssvx
  5. Release the process grid and terminate the MPI environment

With MPICH,  program may be run by typing:
   mpiexec -n <np> pzdrive -r <proc rows> -c <proc columns> big.rua
