Computational demands of fluid flow simulations are high, with large computational resources required to perform the calculations and these applications have recently been accelerated with the help of GPU devices (Graphical Processing Units). Fluid flow simulation using discrete method called lattice Boltzmann (LB) has also been parallelized using GPU. In this paper a single-node multi-GPU implementation of both two-dimensional and three-dimensional fluid flow LB simulation is presented. A configuration with 3 GPU devices connected to the same processor is used to test the developed multi-GPU software and to compare the obtained speed-up relative to the single-GPU implementation.
