“Running on more than 20,000 GPUs at a resolution of 1 km, a 50 billion cell grid, able to capture the atmosphere, a a coupled simulation of the atmosphere, of the land, of the oceans, the most accurate ever achieved, which won the Gordon Bell Prize.”
Key terms
- coupled simulation
- — A simulation that models several interacting systems together, such as atmosphere, land and ocean.
- Gordon Bell Prize
- — An annual award recognising outstanding achievement in high-performance computing applications.
- cell grid
- — The three-dimensional mesh of small volumes a simulation divides the world into; more cells means finer detail and more computation.
