Purpose
=======

The driver program PZDRIVE2.

This example illustrates how to use PZGSSVX to solve systems
repeatedly 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 PZGSSVX:
       ScalePermstruct : perm_c
       LUstruct        : etree

With MPICH,  program may be run by typing:
   mpiexec -n <np> pzdrive2 -r <proc rows> -c <proc columns> g20.rua
