   Description of the test
   ========================

   This test executes the parallel Jacobi iterative method to 
   solve the Laplace's equation using two-dimensional array of processes. 
   The matrix distribution used is blocked homogeneous distribution.

   This test uses MPI.
   
   The time of execution of the algorithm is returned.

   Files
   -----

   jacobi.c  ----> Contains the algorithm execution code
   counter.h ----> Contains the parameters:
                   N=size of the grid
                   NUMBER_OF_ITERATIONS =  number of iterations.

   HOW TO RUN
   ----------

   shell$ hmpibcast jacobi.c counter.h

   shell$ hmpiload -o jacobi jacobi.c

   shell$ hmpirun jacobi
   N=1024, Grid=(3,3), Time(seconds)=10
