Parallelized Mandelbrot set generator

Parallel implementations of Mandelbrot set program, written in a C++ object-oriented approach.

Different versions :

• serial
• OpenMP
• MPI (master/workers with load-balancing)
• hybrid OpenMP+MPI

Output example, for a limits in the complex plane defined by [-0.2, 0.4] x [0.5i, 1.1i] :

It is written in a unique source code. The Makefile controls which version is compiled :

• make srl for serial version
• make omp for OpenMP version
• make mpi
  • with MPI_SIMPLE flag for non-load-balanced version (study purpose only)
  • with MPI_MASTER_WORKERS flag for load-balancing MPI version
• make hyb for hybrid OpenMP+MPI version
• make for all.

Limits of the image are defined by macros at the beginning of the main.cc file. Moreover, various macros can be activated in the Makefile : optional optimizations, computations with std::complex instead of standard floating point numbers, use double precision, print a gradient image instead of black/white one, etc...

A bunch of Python scripts are also provided. Use the make_plots.py to generate every figure that are included in the report. Type python make_plots.py --help to display options. Use the complex_fractals.py to get an animated and colorec view of the Mandelbrot set.
