G8 Initiative: ExArch: Climate Analytics on Distributed Exascale Data Archives

美国国家科学基金会向加州大学洛杉矶分校颁发的这一奖项，资助美国研究人员参加由八国集团研究理事会多边研究倡议通过面向全球规模问题的百亿亿次计算应用软件跨学科计划竞争性选择的项目。这是美国国家科学基金会、加拿大国家科学与工程研究委员会（NSERC）、法国国家研究局（ANR）、德国德国科学促进会（DFG）、日本科学促进会（JSPS）、俄罗斯基础研究基金会（RFBR）和英国研究委员会（RC-UK）之间的试点合作。支持在竞争基础上选出的由至少三个伙伴国家的研究人员组成的合作研究项目。这个国际项目的目标是气候科学数据管理快速增长的需求，因为模型提高了它们描述空间结构的精度和它们描述大量物理过程的完整性。ExArch项目主要是一个框架，用于在peta和exa尺度上对多模型集成进行科学解释。它在即将到来的CMIP5档案的上下文中应用了一个策略、一个原型基础结构和演示使用示例，这将是在这个领域中组装的同类中最大的。它将把ExArch框架与CORDEX实验结合起来，在分辨率上超越CMIP5，尽管是在区域范围内。这个国际项目涉及六个国家的合作研究人员，将探索开发软件管理基础设施的挑战，该基础设施将扩展到数eb的气候数据档案，这些数据可能对本十年末的重大政策决定至关重要。在短期内，将通过将战略应用于现有的数据档案来评价这些战略。美国国家科学基金会对加州大学洛杉矶分校的资助主要支持将信息模型扩展到地球观测数据，并利用观测数据验证区域气候模型。

This NSF award to UCLA funds U.S. researchers participating in a project competitively selected by the G8 Research Councils Initiative on Multilateral Research through the Interdisciplinary Program on Application Software towards Exascale Computing for Global Scale Issues. This is a pilot collaboration among the U.S. National Science Foundation, the Canadian National Sciences and Engineering Research Council (NSERC), the French Agence Nationale de la Recherche (ANR), the German Deutsche Forschungsgemeinschaft (DFG), the Japan Society for the Promotion of Science (JSPS), the Russian Foundation for Basic Research (RFBR),and the United Kingdom Research Councils (RC-UK), supporting collaborative research projects selected on a competitive basis that are comprised of researchers from at least three of the partner countries. This international project targets the rapidly growing demands of climate science data management as models increase the precision with which they depict spatial structure and the completeness with which they describe a vast range of physical processes. The ExArch project is principally a framework for the scientific interpretation of multi-model ensembles at the peta-and exa-scale. It applies a strategy, a prototype infrastructure and demonstration usage examples in the context of the imminent CMIP5 archive, which will be the largest of its kind ever assembled in this domain. It will attach the ExArch framework to the CORDEX experiment, pushing beyond CMIP5 in resolution, albeit at regional scale. This international project involving collaborating researchers in six countries will explore the challenges of developing a software management infrastructure which will scale to the multi-exabyte archives of climate data which are likely to be crucial to major policy decisions by the end of the decade. In the short term, strategies will be evaluated by applying them to existing data archives. The NSF funding to UCLA primarily supports the extension of the information model to earth observational data and the validation of regional climate models with observational data.
