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.

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数TB，计算算法可能非常复杂，以至于它们可能连续运行数周。博尔德科罗拉多大学的物理学小组最后购买的计算机可追溯到2011年之前;虽然这些计算机允许在100多篇论文中发表的工作，但这些机器不再能够更新到当前发布的操作系统，并且比新可用的计算机系统慢得多。该项目将允许购买一套新的计算机和存储设备，以更新该组科学家以更方便的方式获取和分析新的和现有数据集的能力。该小组进行的研究包括（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相关的地震危险，大型俯冲带缓慢滑动的物理学，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RESESS（社区大学生研究经验）附属的暑期实习生的工作，REU网站由NSF根据单独的奖项资助。这组研究人员代表了科罗拉多大学博尔德分校地质科学系和CIRES内的一个连贯单位，在地震学、构造学、地球动力学方面有共同的研究兴趣，并强调实地实验。这里涉及的最常见的需求包括大型（数十兆字节）的存储量，具有对处理核心的高速访问，用于专用软件的快速多核机器，易于从多台计算机访问的大存储量，可以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的访问，创建常规图形和相关的写作。这四个PI正在积极开展由NSF和其他资助机构资助的研究项目。在这个小组内进行的研究发生在地震活动和灾害，大陆变形和结构，地球动力学的广泛主题。许多地震学工作需要收集和分析便携式现场实验以及EarthScope移动式阵列组件和常设地震台站所获得的大量数据子集。其他项目需要分析地震网络的连续数据流，以确定、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学约束进行比较。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
