Purpose

The driver program PDDRIVE2.
This example illustrates how to use  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 PDGSSVX:
       ScalePermstruct : perm_c
       LUstruct        : etree
On an IBM SP, the program may be run by typing:
   poe pddrive2 -r <proc rows>=""> -c <proc columns>=""> <input_matrix> -procs
