Weather, Atmospheric, Ocean Modeling, and Space Sciences

Work computation fluid dynamics applications such as weather and ocean modeling such as WRF (Weather Research and Forecasting model) and Tsunami simulations has shown tremendous speedups that enable savings in time and improvements in accuracy.


WRF Acceleration using CUDA Overall speedup for WRF is 1.25x Michalakes and Vachharajani	Tsunami simulation Dr. Takayuki Aoki

ISV/Application	Supported Features	Expected Speed up*	Release Status
NIM (NOAA)	Most routines	7x	Released
WRF (NCAR)	WSM5, WSM3, Ice Microphysics models	4x-6x	Released, v3.2
ASUCA (JMA)	Most routines	12x	In development
HIRLAM	Dynamical core, solver	3x	In development
