Part of the evaluation of our M1 course in Parallel Algorithm consisted in a small oceanic simulation project using MPI. The problem consists in a 2d grid populated by sharks and sardines, the evolution of which is regulated by local rules. The grid is then splitted into horizontal bands, each of them being treated in parallel in order to gain in efficiency compared to a sequential algorithm. The detailed subject can be found here (page 1 and page 2), along with my report and my source code.
