      Purpose
   =======

   The driver program PZDRIVE3D3.

   This example illustrates how to use PZGSSVX3D to sovle 
   the systems with the same sparsity pattern and similar numerical
   values of matrix A.
   In this case, the row and column permutation vectors and symbolic
   factorization are computed only once. The following data structures
   will be reused in the subsequent call to PZGSSVX3D:
          ScalePermstruct : DiagScale, R, C, perm_r, perm_c
          LUstruct        : etree, Glu_persist, Llu
          SOLVEstruct      : communication metadata for SpTRSV, SpMV, and
                             3D<->2D gather/scatter of {A,B} stored in A3d.

   NOTE:
   The distributed nonzero structures of L and U remain the same,
   although the numerical values are different. So 'Llu' is set up once
   in the first call to PZGSSVX3D, and reused in the subsequent call.

   The program may be run by typing:
      mpiexec -np

 pzdrive3d3 -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, ...)
