Purpose
=======

The driver program PDDRIVE.

This example illustrates how to use PDGSSVX 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 pdgssvx
  5. Release the process grid and terminate the MPI environment

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