%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
   performance degradation.
