 Purpose
 =======

 The driver program pzdrive4_ABglobal.

 This example illustrates how to divide up the processes into
 subgroups (multiple grids) such that each subgroup solves a linear
 system independently from the other.

 In this example, there are 2 subgroups:
  1. subgroup 1 consists of processes 0 to 5 arranged as
     a 2-by-3 process grid.
  2. subgroup 2 consists of processes 6 to 9 arranged as
     a 2-by-2 process grid.

 On an IBM SP, the program may be run by typing
    poe pzdrive4_ABglobal <input_file> -procs 10
