Natural phenomena simulation, such as water and smoke, is a very important topic in order to increase real time scene realism in videogames and general real time simulations. However, this kind of simulation requires numerically solving the Navier-Stokes equations, which is a computationally expensive task. Additionally, to deal more immersing simulation, interaction between the flow and the objects in the scene are needed, which increases even more the computational work. The advent of GPU computing has enabled the development of many strategies for accelerating these simulations. In this paper we propose an scalable architecture for multiples GPUs for fluid simulation, allowing complex fluid behavior for real time applications like games. Also, the techniques explained in this paper could be adapted for others real-time simulations such as physics simulations.
