Updating of Geophysics Computer Facility, University of Colorado/CIRES

现代地质和地球物理科学依赖于在计算机上获取、存储和分析数据。数据集的大小通常是许多TB，而计算算法可能非常复杂，可能会连续运行数周。科罗拉多大学博尔德分校的地球物理学小组最后一次购买的计算机可以追溯到2011年前；虽然这些计算机允许在100多篇论文中发表工作，但这些计算机不再能够更新到当前发布的操作系统，并且比新推出的计算机系统要慢得多。该项目奖将允许购买一套新的计算机和存储设备，这将更新该小组中的科学家以更方便的方式获取和分析新的和现有的数据集的能力。该小组开展的研究包括(但不限于)了解大陆岩石圈的结构和演化、地震的位置和特征、与石油和天然气开发有关的地震灾害、大型俯冲带的慢滑物理以及海啸预警算法的探索性发展。新设备还提高了我们以更直观的方式可视化数据和结果的能力，同时支持研究生和本科生以及隶属于RESESS(社区大学生研究体验)的暑期实习生的工作。RESESS是一个由美国国家科学基金会资助的REU网站，由NSF单独授予。这组研究人员代表着科罗拉多博尔德大学地质科学系和CIRES内部的一个连贯的单位，他们在地震学、构造学、地球动力学和野外实验方面都有共同的研究兴趣。这里解决的最常见需求包括具有对处理核心的高速访问的大容量(10s TB)存储、用于专用软件的快速多核机器、可从多台计算机容易地访问的大存储容量、可创建复杂可视化的计算机、以及较小的本地平台以适应对处理结果的更常规访问、常规图形的创建和相关书写。这四个私人投资机构正在积极开展由国家科学基金会和其他资助机构资助的研究项目。在这一组内进行的研究是在地震活动和灾害、大陆变形和结构以及地球动力学等广泛主题下进行的。许多地震学工作需要收集和分析通过便携式现场实验以及地球望远镜和永久地震台的可移动阵列组件获得的大量数据。其他项目需要分析来自地震台网的连续数据流，以识别、定位和描述不同环境中的地震活动。其他工作需要积累和分析晶体组构，以与地壳深部结构的地震约束进行比较。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Modern geological and geophysical science depends on acquiring, storing, and analyzing data on computers. Data sets are often many terabytes in size, and computational algorithms can be so complex that they might run continuously for weeks on end. Computers that were last purchased by the geophysics group at the University of Colorado, Boulder dated from before 2011; while these permitted allowing work that was published in over 100 papers, these machines are no longer capable of being updated to currently released operating systems and are far slower than newly available computer systemsmachines. This project award will permit the purchase of a new suite of computers and storage devices that will renew the ability of the scientists in this group to acquire and analyze new and existing datasets in a far more expedient manner. The research conducted by this group includes (but is not limited to) understanding the structure and evolution of continental lithosphere, the location and characterization of earthquakes, seismic hazards associated with oil and gas development, the physics of slow slip at large subduction zones, and exploratory development of tsunami warning algorithms. The new equipment also improves our ability to visualize data and results in more intuitive ways while supporting work from graduate and undergraduate students as well as summer interns affiliated with RESESS (Research Experiences for Community College Students) an REU site funded by NSF under a separate award..This group of researchers represents a coherent unit within the Department of Geological Sciences and CIRES at the University of Colorado Boulder with mutual research interests in seismology, tectonics, geodynamics, and an emphasis on field experiments. The most common needs addressed here include large (10s of terabytes) amounts of storage with highspeed access to a processing core, fast multicore machines for specialized software, a large storage volume that is readily accessible from multiple computers, computers where sophisticated visualizations can be created, and smaller local platforms to accommodate the more routine accessing of processed results, creation of routine graphics and associated writing. The four PIs are actively working on research projects funded by NSF and other funding agencies. Research conducted within this group occurs within the broad themes of seismicity and hazards, continental deformation and structure, and geodynamics. Much of the seismological work requires the collection and analysis of large subsets of data acquired by portable field experiments as well as the Transportable Array component of EarthScope and permanent seismic stations. Other projects require the analysis of continuous datastreams from seismic networks to identify, locate and characterize seismicity in different environments. Other work requires the accumulation and analysis of crystallographic fabrics for comparison with seismological constraints on structures within the deep crust.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
