 Purpose
 =======

 The driver program pddrive1_ABglobal.

 This example illustrates how to use pdgssvx_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
 pdgssvx_ABglobal, and reuse the following data structures
 in the subsequent call to pdgssvx_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 pddrive1_ABglobal -r <proc rows>=""> -c <proc columns>=""> <input_matrix> -procs
