Short summary
We develop an ocean general circulation model based on heterogeneous computing architectures. The model is optimized to address a series of challenges that are particularly crucial for kilometer-scale resolution ocean modeling. We conduct a short-term global simulation test with a horizontal resolution of 2 km. The simulation demonstrates the high capacity of the model to capture the oceanic meso- to submesoscale processes.
