 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

 On an IBM SP, the program may be run by typing
    poe pddrive -r <proc rows>=""> -c <proc columns>=""> <input_file> -procs
