      Purpose
   =======

   The driver program PSDRIVE3D2.

   This example illustrates how to use PSGSSVX3D to sovle 
   the systems with the same sparsity pattern of matrix A.
   In this case, the column permutation vector ScalePermstruct->perm_c is
   computed once. The following data structures will be reused in the
   subsequent call to PSGSSVX3D:
          ScalePermstruct : perm_c
          LUstruct        : etree
          SOLVEstruct     : communication metadata for SpTRSV, SpMV, and
                            3D<->2D gather/scatter of {A,B} stored in A3d.

   The program may be run by typing:
      mpiexec -np

 psdrive3d2 -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, ...)
