 Purpose
 =======

 The driver program pzdrive2_ABglobal.

 This example illustrates how to use pzgssvx_ABglobal 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_ABglobal:
        ScalePermstruct : perm_c
        LUstruct        : etree

 On an IBM SP, the program may be run by typing:
    poe pzdrive2_ABglobal -r <proc rows>=""> -c <proc columns>=""> <input_matrix> -procs
