SUMMARY:Toward Realization of Numerical Towing-Tank Tests by Wall-Resolved
  Large Eddy Simulation Based on 32 Billion Grid Finite-Element Computation
DESCRIPTION:ACM Gordon Bell Finalist, Awards Presentation\n\nToward Realiz
 ation of Numerical Towing-Tank Tests by Wall-Resolved Large Eddy Simulatio
 n Based on 32 Billion Grid Finite-Element Computation\n\nKato, Yamade, Nag
 ano, Kumahata, Minami...\n\nTo realize numerical towing-tank tests by subs
 tantially shortening the time to the solution, a general-purpose finite-el
 ement flow solver, named FrontFlow/Blue (FFB), has been fully optimized so
  as to achieve the maximum possible sustained memory throughputs with thre
 e of its four hot kernels. As a result, a single-node sustained performanc
 e of 179.0 GFLOPS, which corresponds to 5.3% of the peak performance, has 
 been achieved on Fugaku, the next flagship computer of Japan. A weak-scale
  benchmark test has confirmed FFB runs with a parallel efficiency of over 
 85% up to 5,505,024 compute cores, and a sustained performance of 16.7 PFL
 OPS has been achieved. By these, the time needed for large-eddy simulation
  using 32 billion grids has been significantly reduced from almost two day
 s to only 37 min., or by a factor of 71. This has clearly indicated that a
  numerical towing-tank could actually be built for ship hydrodynamics in a
  few years.\n\nRegistration Category: Tech Program Reg Pass
