DescriptionIn this work, we discuss the possibility of using GPGPU techniques for Aeroacoustic Simulation (especially for flue instruments) with the finite-difference lattice Boltzmann method (FDLBM). Compressible flow simulation has been used in direct aeroacoustic simulation; however, the computational cost is huge due to the requirement of high computational mesh resolution, with small time steps. The lattice Boltzmann method (LBM) has been used as an efficient method for fluid simulation using GPGPU. However, LBM is not accurate enough when applied to some aeroacoustic problems. On the other hand, FDLBM is able to use high-order finite-difference schemes and it has a high arithmetic intensity compared to LBM. We present a performance evaluation of the LBM and FDLBM with several finite-difference schemes on GPU with the roofline model.
