Interactive Simulation and Visualization of Atmospheric Large-Eddy Simulations

In this paper, we present GALES: our physicallycorrect, GPU-accelerated, Atmospheric LargeEddy Simulation. GALES is a mixed-precision LES implementation using NVIDIA’s CUDA to parallelize and accelerate computation while also providing interactive visualization. GALES, with visualization, outperforms an existing LES implementation running on 32 processor cores of a supercomputer. We demonstrate physical correctness by comparing GALES’s results to those of other LES implementations. The ability to run interactive, scientific simulations on a desktop computer offers new possibilities for atmospheric researchers.
