Piz Kesch: The Making of a GPU-based Weather Forecasting System

Thomas Schulthess from CSCS presented this talk at the Nvidia booth at SC15. “On October 1, 2015 “Piz Kesch”, a Cray CS-Storm system with NVIDIA K80 GPUs became operational at CSCS on behalf of MeteoSwiss. In this talk, we will discuss the hardware-software co-design project behind this most cost and energy efficient system for numerical weather prediction.”
