Computational Fluid Dynamics

Several ongoing projects on Navier-Stokes models and Lattice Boltzman methods have shown very large speedups using CUDA-enabled GPUs. This work is highlighted below starting with some charts, followed by links to technical reports. There is also work on weather modeling and ocean modeling using GPUs.
