Exploring GPGPU Acceleration of Process-Oriented Simulations

Authors: Barnes, Frederick R. M., Pressnell, Thomas, Le Foll, Brendan

Abstract:

This paper reports on our experiences of using commodity GPUs to speed-up the execution of fine-grained concurrent simulations. Starting with an existing process-oriented "boids" simulation, we explore a variety of techniques aimed at improving performance, gradually refactoring the original code. Successive improvements lead to a 10-fold improvement in performance, which we believe can still be improved upon, allowing us to explore simulations with larger numbers of agents (30,000 rather than 2,000) interactively and without significant performance degradation.
