Purpose
=======

The driver program psdrive2_ABglobal.

This example illustrates how to use psgssvx_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 psgssvx_ABglobal:
       ScalePermstruct : perm_c
       LUstruct        : etree

On an IBM SP, the program may be run by typing:
   poe psdrive2_ABglobal -r <proc rows> -c <proc columns> <input_matrix> -procs
