地球系统模式公共软件平台研发

Development of Community Software Platform for Earth System Modeling

地球系统模式是研究气候变化最重要的数值模拟工具。发展地球系统模式科学与工程并重,多圈层/多尺度耦合、复杂参数化、大规模计算和海量数据诊断分析使得模式的发展面临日益巨大的挑战。应对这些挑战,提高模式专家研究和开发效率成为模式发展的关键之一。当前,支持模式发展的软件工具存在分散、低效、兼容性差以及仍严重依赖脚本等问题,还无法形成一个统一的软件平台,以有效支持模式开发的全流程和促进不同领域、不同模式团队研究者之间的高效知识共享。因此,亟需研制一套支撑地球系统模式发展的公共软件平台,有效连接开发者与用户,高效使用高性能计算环境。该公共软件平台包含试验场景系统、诊断评估系统、物理方案参数分析与优化系统、集成耦合系统、模式大数据平台5个子系统,各子系统既可以独立运行与应用,也可以连接成为整体。

The earth system model is the one of the most important numerical simulation tool for the study of climate change. The development of the earth system model brings challenges in both science and engineering aspects. The coupling of different spheres and scales, the complex parameterization schemes, as well as the largescale computation and big data analytics make it more and more challenging to improve the current models. Along such development, improving the research and development efficiency becomes the key factor. Nowadays, the software tools that support the model development have disadvantages in efficiency, compatibility, and the poor user experience that mainly rely on shell scripts. Therefore, we face the urgent demand for a unified public software platform, which can efficiently support the entire cycle of model development, promote the sharing of experience and knowledge among different model developers, connect the developers and the users, and make effective utilization of HPC environments. Such a public software platform includes five different sub-systems, which are the test scenario sys- tem, the diagnosis and evaluation system, the parameter analysis and tuning system, the integrated coupling system, and the model big data platform. The sub-systems can run as standalone systems, and can also be used as an integrated workflow.
