Purpose
=======

The driver program psdrive1_ABglobal.

This example illustrates how to use psgssvx_ABglobal to
solve systems with the same A but different right-hand side.
In this case, we factorize A only once in the first call to
psgssvx_ABglobal, and reuse the following data structures
in the subsequent call to psgssvx_ABglobal:
       ScalePermstruct  : DiagScale, R, C, perm_r, perm_c
       LUstruct         : Glu_persist, Llu

On an IBM SP, the program may be run by typing:
   poe psdrive1_ABglobal -r <proc rows> -c <proc columns> <input_matrix> -procs
