Purpose
=======

The driver program psdrive4_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 psdrive4_ABglobal <input_file> -procs 10
