Acceleration of a Novel Rotorcraft Wake Simulation
Speakers:

Abstract:
Dive deep as we present the details of a new CUDA-based algorithm for accurate rotorcraft wake simulations. We use a vortex particle method, accelerated with a multipole tree algorithm, combined with a traditional grid-based CFD code. This CUDA algorithm can evaluate the velocity and velocity-gradient with an effective throughput approaching 300 billion interactions per second on a C1060. This gives 10x speed-up and 2.5x better accuracy compared to the parallel CPU version.
