EA: Upgrading the Geophysics Computing Facility at Arizona State University

该合同将替换和更新亚利桑那州立大学地球与空间探索学院地球物理计算设施（GCF）老化和故障的服务器。这个计算设施已经支持地震研究生、本科生、博士后研究人员、研究人员和教职员工的研究超过二十年，产生了各级学位，在学术界和工业界的工作安排，以及数百次会议演讲，研究成果发表在100多篇同行评审的期刊文章中。新的计算机系统将取代那些已经使用了大约10年、出现严重故障迹象的服务器。新系统包括：(1)所有用户的主服务器，所有软件包，并将处理我们不断增长的全球地震数据集的海量存储；（二）备份服务器；(3)和一个小型防火墙服务器。新计算机系统的首要目标将是支持当前和未来nsf资助的研究项目，主要集中在地球和行星内部的前沿研究。新系统是专门为使用大量全球数据集进行内部地震测绘的范式转变而设计和构建的，并采用自动化方法来挖掘、处理和分析数据。所有开发的软件、数据产品和模型都将向公众开放。新系统将允许在地球和行星内部的地震/地球物理研究方面继续指导和培训学生和博士后，这有助于他们成功地找到工作。亚利桑那州立大学是一所西班牙裔服务机构，也是美国最大的公立大学之一，拥有多元化的人口。亚利桑那州立大学的GCF将继续使未被充分代表的人群接触到nsf资助的研究，更广泛地说，接触到从事科学研究的兴奋。亚利桑那州立大学地球与空间探索学院积极支持归属感、可及性、正义、公平、多样性和包容性。该合同将替换和更新亚利桑那州立大学地球与空间探索学院老化和故障的GCF服务器。基金支持地震专业研究生、博士后、科研人员和教职工的科研工作，支持本科生科研项目。目前，GCF中已有十年历史的服务器显示出严重故障的迹象：我们的两个主服务器上的磁盘控制器和硬盘都出现了故障（导致存储容量损失）。此外，最重要的是，硬件现在太老了，无法进行操作系统更新，这不仅带来了安全问题，而且有效地阻碍了正在进行的研究活动。这笔赠款将用于购买三台新服务器，以取代老化的四台服务器系统。新系统包括一个主服务器，它将容纳所有用户帐户、所有软件包，并将处理不断增长的全球地震数据集的海量存储；它还将包括一个备份服务器和一个小型防火墙服务器。主服务器将托管我们小组最近编写的一个软件套件，它可以自动收集（很快就会自动处理）来自近二十多个数据机构的数据。这个“大数据”项目涉及超过150tb的存储容量。服务器是为各种地震研究项目的需求量身定制的，允许我们的nsf资助的研究活动，如代码开发，访问GCF内部的全球地震数据的海量存储，以及数据处理的软件应用程序，以及web服务和备份。研究人员可以通过计算机上的远程连接，从任何地方访问集中式更新的GCF系统。这种集中式服务器模型对于我们的大型数据集和大量的计算地震研究需求是有效的，因为不可能在本地用户机器上本地存储GCF数据和软件的一小部分。根据不断增长的全球数据集创建的计划数据产品将使传统地震学学生以外的研究指导成为可能。这次计算机系统的升级将使我们能够继续努力，把令人兴奋的科学研究带给公众、新闻媒体、各级学生以及科学界。该奖项反映了美国国家科学基金会的法定使命，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。

This award will replace and update the aging and failing servers of Geophysics Computing Facility (GCF) in the School of Earth and Space Exploration at Arizona State University (ASU). This computational facility has supported the research of seismological graduate students, undergraduate students, postdoctoral researchers, research staff, and faculty for well over two decades, resulting in degrees at all levels, job placements in academia and industry, as well as hundreds of conference presentations with research results published in over 100 peer-reviewed journal articles. The new computer system will replace servers that are roughly a decade old and showing signs of critical failure. The new system includes (1) a main server for all user account homes, all software packages, and will handle mass storage for our growing global seismic data set; (2) a backup server; and (3) and a small firewall server. The overarching objective of the new computer system will be to support both current and future NSF-funded research projects, which predominantly focuses on cutting-edge investigations of Earth and planetary interiors. The new system is specially designed and built for a paradigm shift in seismic mapping of the interior using massive global data sets, and automated methodologies to mine, process, and analyze the data. All developed software, data products, and models will be made publicly available. The new system will allow continued mentoring and training of students and postdocs in seismological/geophysical research on Earth and planetary interiors, which helps them in successful job placement. ASU is a Hispanic Serving Institution and one of the largest public universities in the US with a diverse population. ASU's GCF will continue to expose underrepresented populations to NSF-funded research, and more broadly, to the excitement of doing science. ASU's School of Earth and Space Exploration proactively supports belonging, accessibility, justice, equity, diversity, and inclusion.This award will replace and update the aging and failing servers of the GCF in the School of Earth and Space Exploration at ASU. The GCF supports the research of seismological graduate students, postdoctoral researchers, research staff, and faculty as well as undergraduate research projects. The current, decade old servers in the GCF are showing signs of critical failure: disk controllers as well as hard disks have failed on our two main servers (resulting in loss of storage capacity). In addition, and most importantly, the hardware is now too old for operating system updates which not only present a security issue but effectively stunts ongoing research activities. Funds from this grant will be used to purchase three new servers to replace the aging four-server system. The new system includes a main server that will house all user account homes, all software packages, and will handle mass storage for our growing global seismic data set; it will also include a backup server and a small firewall server. The main server will host a software suite recently written by our group that automatically collects (and soon will automatically process) data from nearly two dozen data agencies. This “big data” project involves storage capacity of over 150 Tb. Servers are tailored to the variety of seismological research project needs, allowing our NSF-funded research activities such as code development, access to GCF's in-house mass storage of global seismic data, and software applications for data processing, as well as web services and backups. Researchers can access the centralized updated GCF system from anywhere, via a remote connection on their computers. This centralized server model is effective for our large data set and heavy computational seismological research needs, since it is not possible to locally store even a fraction of the GCF data and software on local user machines. Research mentoring beyond traditional seismology students will be made possible from planned data products created from the growing global data set. This computer system upgrade will allow us to continue efforts to bring the excitement of scientific research to the public, the news media, students at all levels, as well as the scientific community.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.
