      Purpose
   =======

   The driver program PSDRIVE3D1.

   This example illustrates how to use PSGSSVX3D to sovle the systems
   with the same A but different right-hand side, possibly with
   different number of right-hand sides.
   In this case, we factorize A only once in the first call to PSGSSVX3D,
   and reuse the following data structures in the subsequent call to
   PSGSSVX3D:
          ScalePermstruct  : DiagScale, R, C, perm_r, perm_c
          LUstruct         : Glu_persist, Llu
          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

 psdrive3d1 -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, ...)
