Abstract

Abstract: Numerical ocean models are an important means for humans to study ocean activities today. For decades, with the continuous improvement of supercomputer performance, the application of numerical ocean models in high-performance computing has also developed rapidly. The birth and progress of high-performance cloud computing provide an opportunity for the development of portability and reproducibility of the ocean model. This paper uses container technology to construct the working environment of the Regional Oceanic Modeling System (ROMS), and rapidly completes the calculation jobs of the ocean model on the high-performance cloud computing platform. At the same time, we compare and analyze the operating performance of traditional HPC VM clusters. The new ocean model system we constructed based on high-performance cloud computing can provide better portability and convenience without wasting performance on traditional HPC clusters. It provides a new tool for scientists to quickly build ocean model clusters suitable for different hardware configurations, and to perform numerical ocean model calculations more conveniently.
