摘要: Abstract We present a fully multi-GPU-based double-precision solver for the three-dimensional two-phase incompressible Navier–Stokes equations. It is able to simulate interaction of two fluids like air and water based on level-set approach. High-order finite difference schemes Chorin’s projection approach space time discretization are applied. An in-depth performance analysis shows realistic speed-up order three by comparing equally priced GPUs CPUs more than doubling in energy efficiency GPUs. observe profound strong weak scaling different multi-GPU clusters.
