%X 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
\[dq]boids\[dq] 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
