DescriptionSurfaces waves are the most energetic motion in global ocean and are crucially important to marine safety and climate change. High-resolution global wave model plays a key role for accurate wave forecasting. However, the parallel efficiency with large amount of computation is a big barrier for this type of model. In this work, breakthroughs in the design and application of irregular quasi-rectangular grid decomposition, master-slave cooperative computing workflow, and pipelining schemes for high resolution global wave model have been achieved. Based on these innovations, ultra-high horizontal resolution of (1/60)◦ by (1/60)◦ global wave model is implemented on the Sunway TaihuLight Supercomputer with 123.6 PFlops peak performance. Preliminary results show peak performance of our model can reach 35.97 PFlops with a full-scale system consisting of 10,495,680 cores. Final results before performance update deadline should be higher. These innovations provide good scalability and high efficiency for the ultra-high resolution global wave model.
