SUMMARY:Numerical Simulation of a Flue Instrument with Finite-Difference L
 attice Boltzmann Method using GPGPU
DESCRIPTION:Ryoya Tabata (Kyushu Institute of Technology)\n\nIn this work,
  we discuss the possibility of using GPGPU techniques for Aeroacoustic Sim
 ulation (especially for flue instruments) with the finite-difference latti
 ce 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 effici
 ent method for fluid simulation using GPGPU.  However, LBM is not accurate
  enough when applied to some aeroacoustic problems.  On the other hand, FD
 LBM 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 t
 he roofline model.\n\nRegistration Category: Tech Program Reg Pass, Exhibi
