Short summary
Accurate computer simulations are critical to understanding how climate change will affect local communities. An important part of such simulations is sea ice, which affects even distant areas in the long term. In our work, we explore how GPUs (graphics processing units), computer chips originally designed for gaming allow for faster simulation of sea ice with a new software, the neXtSIM-DG dynamical core. We discuss multiple options and demonstrate that using GPUs makes more accurate simulations feasible.
