Parallel calculations in models of the general atmosphere circulation

Abstract

This paper describes a method for organizing parallel computing on graphics processors using CUDA technology, in relation to the general circulation model of the lower and middle atmosphere of the Earth. This model is being developed at the Polar Geophysical Institute and is based on the numerical integration of a complete system of equations for the dynamics of viscous atmospheric gas on a high-resolution spatial grid in a spherical layer around the Earth's surface. The model includes a block for calculating the transfer of solar and thermal radiation, which also uses parallel calculations based on CUDA technology.
