Parallel Programming project

Parallel implementation of a genetic algorithm for the reconstruction of an image using the minimal possible amount of polygons.

Compilation

To compile, be sure to have the following dependencies:

• CMake >= 2.8
• OpenCV >= 3.0.0
• Either:
  • GNU C++ Compiler + OpenMPI
  • Intel C++ Compiler + Intel MPI

To compile, use the standard CMake commands. In the root directory of the repository:

mkdir -p {build,output}
cd build && rm -rf *
cmake ..
make -j4 && cd ..

Running

To run the algorithm, it can be done either with mpirun or without it. If only 1 process is specified, the program still runs, disabling any parallel code.

export P=<number of processes>
export INPUT_IMAGE=<path to input file>
export OUTPUT_IMAGE=<path to output file>
export EPOCHS=<expected number of epochs>
mpirun -np $P ./ParallelGenetic -e $EPOCHS -i $INPUT_IMAGE -o $OUTPUT_IMAGE 

For the program to work as expected, the output directory must exist.
