Parallel Modeling of Fish Interaction

This paper summarizes our work on a parallel algorithm for an interacting particle model, derived from the model by Czirok, Vicsek, et. al. [4, 5, 6, 15, 16]. Our model is particularly geared toward simulating the behavior of fish in large shoals. In this paper, the background and motivation for the problem are given, as well as an introduction to the mathematical model. A discussion of implementing this model in MATLAB and C++ follows. The parallel implementation is discussed with challenges particular to this mathematical model and how the authors addressed these challenges. Load balancing was performed and is discussed. Finally, a performance analysis follows, using a performance metric to compare the MATLAB , C+ + , and parallelized code.
