A Flexible High-Performance Lattice Boltzmann GPU Code for the Simulations of Fluid Flows in Complex Geometries

We describe the porting of the Lattice Boltzmann component of MUPHY, a multi-physics/scale simulation software, to multiple graphics processing units using the Compute Unified Device Architecture. The novelty of this work is the development of ad hoc techniques for optimizing the indirect addressing that MUPHY uses for efficient simulations of irregular domains.Engineering and Applied SciencesPhysic
