This directory uses a 2-D grid solver to solve a heat transfer problem
as an example of a program using MPI.

Files:
    heat.py hshow.py
	Python heat transfer solving program.
	Can generate interesting visualizations when run with -V option

	Run ./heat.py -h for information about command-line options

    Makefile
        Shows sample demonstrations.  Run 'make demoX' for X between 1 and 4

    seq:
        Subdirectory containing C version of solver designed for
	sequential execution.  Can also get parallelism with OpenMP

    mpi:	
        Subdirectory containing C version of solver designed for
	parallel execution under MPI.  Partitions grid into regions,
	each containing a subset of rows.  Each process computes state
	values for its region and communicates boundary rows with its
	north and south neighbors.
