The driver program PSDRIVE3D.

Purpose
=======

This example illustrates how to use PSGSSVX3D or PSGSSVX3D_CSC_BATCH
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 psgssvx
  5. Release the process grid and terminate the MPI environment

The program may be run by typing
   mpiexec -np 

 psdrive3d -r <proc rows> -c <proc columns> \
                                  -d <proc Z-dimension> <input_file>
NOTE: total number of processes p = r * c * d
      d must be a power-of-two, e.g., 1, 2, 4, ...
