Acquisition of an Earth System Modeling Facility for Coupled Climate, Chemistry, and Biogeochemistry Studies

这笔重大研究仪器(MRI)赠款支持购买一台高性能计算机和存储系统，作为加州大学欧文分校(UCI)地球系统建模设施(ESMF)的核心部件。UCI ESMF将致力于整合、综合和分析大型模型和数据集，以促进对地球系统耦合的物理气候、化学和生物地球化学循环的基本理解。它是为合并ESM组成部分(例如，大气、海洋、化学、生物、陆地水文学)量身定做的，这些组成部分通常会消耗个别研究项目的可用计算资源。虽然ESMF主要是教师和研究生研究人员的开发设施，但它将产生基础科学研究所需的长达十年的耦合系统模拟。在计算能力方面，ESMF适合个人PI和基于学校的资源和国家建模设施，但在发展方面它是独一无二的。UCI ESMF填补了一个利基市场，允许教师、研究生和学生在他们控制计算机和代码开发的环境中使用高性能计算。正在购买的系统是IBM处理器p655 Power4系统，类似于国家大气研究中心最快的生产系统，但比它小得多。广泛的影响包括使用地球系统模型的结果来更好地为环境和能源政策决策提供信息，以及对学生进行地球系统建模方面的教育和培训，其中包括来自附近少数族裔服务机构的学生，加州州立大学贝克斯菲尔德分校(CSUB)。

This Major Research Instrumentation (MRI) grant supports the purchase of a high-performance computer and storage system as the centerpiece for the University of California-Irvine (UCI) Earth System Modeling Facility (ESMF). The UCI ESMF will be devoted to the integration, synthesis, and analysis of large models and datasets required to advance fundamental understanding of the coupled physical climate, chemistry, and biogeochemical cycles of the Earth system. It is tailored for the merging of ESM components (e.g., atmosphere, oceans, chemistry, biology, land hydrology) that normally consume the available computing resources of individual research projects. Although primarily a development facility for faculty and graduate researchers, the ESMF will produce the decade-long simulations of the coupled system that are needed for basic scientific studies. In terms of computing power, the ESMF fits between individual PI and school-based resources and national modeling facilities but in terms of development it is unique. The UCI ESMF fills a niche, allowing faculty, post-graduates, and students to work with high-performance computing in an environment where they control the computer and the code development. The system being purchased is an IBM 64 processor p655 Power4 system, similar to, but (much) smaller than, the fastest production systems at the National Center for Atmospheric ResearchBroader impacts include use of results from Earth system models to better inform environmental and energy policy decision-making and education and training of students in Earth system modeling, including students from a nearby Minority Serving Institution, California State University at Bakersfield (CSUB).
