This directory contains the source code for two examples,
the n-body problem and (the ever-popular) viewing the
Mandelbrot set.


Parallel Mandelbrot in MPI
Written by Ed Karrels, karrels@mcs.anl.gov

This is a demo of the graphical tools built into MPE.  It
includes rudimentary drawing routines and some simple
mouse handling routines.

A listing of command line options will be printed if run
with the '-h' option.

When not reading coordinates from a file and -zoom is not
specified, after an image is complete the program will
wait for the user to drag the first mouse button over a
region.  When the mouse button is released, the program
will zoom in on the selected region.

Sorry, there is no good way to shut down the program when
it is running in a loop through an input file or with
zooming active.  I'm working on it...

For example, to start by viewing the entire set with the
option to zoom:

  pmandel -rmin -2 -rmax 2 -imin -2 -imax 2 +zoom

Try including the 'cool.points' file to see a series of
interesting regions:
  
  pmandel -i cool.points -loop
  (good demo!)
