Purpose
=======

The driver program PSDRIVE4.

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.

With MPICH,  program may be run by typing:
   mpiexec -n 10 psdrive4 big.rua
