MLBROT

Zooms in Mandelbrot Set, to produce nice fractal images.
This is version 1.02.

To compile, you need:
  OCaml 4.07.0
  Camlp5 4.06-exp
and at least one of the following graphic toolkits libraries installed:
  OpenGL
  Lablgtk2
  Olibrt
and, recommended, but optionnal, the multiprecision library:
  GMP (more precisely, its sub-library MPZ)

GRAPHIC TOOLKIT LIBRARIES

The graphic toolkit libraries allow to display the images. At run time,
you can choose with which graphic toolkit library you want the images
to be displayed among the ones found by 'configure' (see below).

All graphic toolkit libraries don't have exactly the same interfaces,
due to historical reasons. The nicest interface is by the graphic toolkit
library:
  Lablgtk2

MULTIPLE PRECISION LIBRARY

If the library GMP/MPZ (multiprecision library) is installed, it
allows to zoom more. Otherwise, from the zoom 2^46 on, the quality
of the images deteriorates.

COMPILATION

Type:
   ./configure
   make

Command:
   ./mlbrot

Type option "-help" to see its options.

INSTALL

No installation provided. The program must be run in its directory.

IMPROVE COMPUTATION SPEED USING MACHINE SLAVES

Compile mlbrot in some machines <foo>, <bar> or any other machines you
can access by ssh with, say, login <login>.

When you launch mlbrot, use option "-hiring 8888".

To add slaves, if machine <foo> has, say, 4 cores, do:

  ssh -xf -f <login>@<foo> -R8889:localhost:8888 "
cd <the mlbrot directory>;
nice ./mlbrot_slave -q -n 1 localhost:8889 &
nice ./mlbrot_slave -q -n 2 localhost:8889 &
nice ./mlbrot_slave -q -n 3 localhost:8889 &
nice ./mlbrot_slave -q -n 4 localhost:8889"

Do the same for machine <bar> or any other machines.

The ports 8888 and 8889 can be actually any port number > 1024 which
is available (error message if not).
