Purpose
=======

The driver program pddrive_ABglobal.

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

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