项目摘要

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。数据集的大小通常有很多 TB，计算算法可能非常复杂，以至于它们可能会连续运行数周。科罗拉多大学博尔德分校地球物理小组最近一次购买的计算机是 2011 年之前；虽然这些允许在 100 多篇论文中发表工作，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机器慢得多。该项目奖将允许购买一套新的计算机和存储设备，这将更新该小组科学家以更方便的方式获取和分析新数据集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灾害、大俯冲带慢滑移的物理学以及海啸预警算法的探索性开发。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（社区学院学生研究体验）的暑期实习生的工作，RESESS 是由 NSF 单独资助的 REU 网站..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 内的一个团结的单位，在地震学、构造学、地球动力学方面有共同的研究兴趣，并重点关注现场实验。这里解决的最常见需求包括可高速访问处理核心的大量（数十 TB）存储、用于专用软件的快速多核机器、可从多台计算机轻松访问的大存储量、可以创建复杂可视化的计算机，以及更小的本地平台，以适应对处理结果的更多例行访问、例行图形的创建和相关写入。四位 PI 正在积极开展由 NSF 和其他资助机构资助的研究项目。该小组进行的研究涉及地震活动和灾害、大陆变形和结构以及地球动力学等广泛主题。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 EarthScope 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网络的连续数据流，以识别、定位和表征不同环境中的地震活动。其他工作需要积累和分析晶体结构，以便与深部地壳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智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
