Intellectual MeritProject proposes a three-year research and development effort, aimed at enabling a broad climate science capability for petascale systems, with four major thrusts:? Investigating the suitability of next-generation computer languages andcompilers in prototype petascale coupler component design.? Extending the Flux Coupler design to efficiently support embedded ensemble based climate modeling techniques.? Providing rich opportunities for interdisciplinary research and education bybringing computer scientists and climate researchers and their graduate students together to work on this project.? Working with the CCSM core group and others to ensure the fullest possibledissemination of our software and results.Investigators will use novel interactive ensemble and stochastic physics techniques to obtain new insights about many basic but poorly understood questions in climate dynamics that depend on the stochastic nature of fluctuations in the Earth?s atmosphere, oceans, cryosphere, and land surface. Interactive ensembles embedded in climate models will enable the non-trivial use of large processor counts within a single coupled climate application. The flexibility and power of PGAS languages will be used address the scalability and complexity challenges of the petascale Flux Coupler.Broader ImpactsThe CCSM is a community model used by hundreds of researchers, and is one of theclimate models used in the International Panel on Climate Change (IPCC) assessments. By enabling the CCSM to make use of petascale systems, this project will permit the U.S. to keep pace with similar efforts in Europe and Japan. This research will provide a basis for improving our understanding of the role of noise in climate system dynamics for seasonal prediction and global climate change. While this proposal focuses on climate science, the byproducts of the work are applicable to coupled modeling problems in other science and engineering fields, particularly the geosciences, and can inform the long-range design plans of other coupling tools and frameworks. Finally, the project willbring together graduate students in computer science and climate science to work on petascale problems, thus training the next generation of computational scientists.

智能项目提出了一项为期三年的研究和开发工作，旨在为千万亿级系统提供广泛的气候科学能力，有四个主要重点：？研究下一代计算机语言和编译器在千万亿级耦合器原型元件设计中的适用性。扩展通量耦合器的设计，以有效地支持嵌入式集成为基础的气候建模技术。通过将计算机科学家和气候研究人员及其研究生聚集在一起进行这个项目，为跨学科研究和教育提供了丰富的机会。与CCSM核心小组和其他人员合作，确保我们的软件和结果得到尽可能充分的传播。研究人员将使用新颖的交互系综和随机物理技术，对气候动力学中许多基本但知之甚少的问题获得新的见解，这些问题取决于地球波动的随机性质。大气、海洋、冰冻圈和陆地表面。嵌入在气候模型中的交互式集成将使在单个耦合气候应用程序中使用大型处理器计数成为可能。PGAS语言的灵活性和强大功能将用于解决千万亿次Flux耦合器的可扩展性和复杂性挑战。更广泛的影响CCSM是一个由数百名研究人员使用的社区模型，也是国际气候变化专门委员会（IPCC）评估中使用的气候模型之一。通过使CCSM能够使用千兆级系统，该项目将使美国能够跟上欧洲和日本的类似努力。该研究将为进一步认识噪声在气候系统动力学中的作用、季节预测和全球气候变化提供基础。虽然该建议侧重于气候科学，但工作的副产品适用于其他科学和工程领域的耦合建模问题，特别是地球科学，并且可以为其他耦合工具和框架的长期设计计划提供信息。最后，该项目将把计算机科学和气候科学的研究生聚集在一起，研究千万亿次问题，从而培养下一代计算科学家。
