Title:
Massively-parallel multi-GPU simulations for fast and accurate automotive aerodynamics 
Abstract:
In this paper, the scaling properties of the commercial Computational Fluid Dynamics (CFD) solver ultraFluidX are analyzed. The solver is based on the Lattice Boltzmann Method (LBM), is explicit in time, inherently transient and only requires next-neighbor information on the computational grid. ultraFluidX thus highly benefits from the computational power of Graphics Processing Units (GPUs). Additionally, the solver can make use of multiple GPUs on multiple compute nodes through an efficient imp...    »
