A wide variety of physical phenomena can be modeled with particles. Such simulations pose interesting challenges for parallel machines since the computations are often difficult to load-balance and can require irregular communication. We discuss the size of problems that can be simulated today, obstacles to higher performance, and areas where algorithmic improvements are need. The relevant issues are illustrated with two prototypical simulations: a Monte Carlo model of low-density fluid flow and molecular dynamics.
