 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
