Upgrading of Infrastructure for Computational Geophysics

[0421861]戴维斯：这笔拨款将用于支持塞西尔·H.和艾达·M.格林地球物理和行星物理研究所（IGPP）的通用计算环境升级，以便学生、教职员工和研究人员能够更好地研究许多现代地球物理问题，这些问题的分析需要对大型数据集进行计算密集型操作，并具有将结果的详细、复杂图像可视化的能力。购买的资源将用于推进海洋地震方法的研究、海洋中脊过程的解释、全球地震学、地幔对流、地磁、次声、空间大地测量学和其他科学项目。计算集群和高性能工作站将为台式机无法解决的大问题提供强大的计算能力。网络附加存储设备将以一种有效的方式促进公共数据集的共享，并为每个部门成员提供一个公共工作目录，可以从IGPP局域网（LAN）上的所有机器以非常高的速度访问。工作站将为研究生提供完成课堂练习和开始论文研究的工具。总的来说，这些设备的增加将简化IGPP LAN的管理，并允许负担过重的IT专业人员将精力集中在更富有成效的活动上。改善当地基础设施将立即提供一个更可靠和稳定的渠道，外部用户可以通过它访问IGPP的几个设施，这些设施由其他部门或其他大学的科学家共享和/或访问。主要的例子包括IRIS/IDA地震数据收集中心、Scripps轨道和永久阵列中心以及SIO可视化中心。＊＊＊

0421861DavisFunds from this grant will support an upgrade to the general computing environment at the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics (IGPP) so that students, staff and faculty researchers can better study some of the many modern geophysical problems whose analysis requires computationally intensive manipulation of large data sets and the capability to visualize detailed, complex images of the results. The resources to be purchased will be used to advance research in marine seismic methods, interpretation of mid-ocean ridge processes, global seismology, mantle convection, geomagnetism, infrasound, space geodesy, and other scientific projects. A compute cluster and high performance workstations will provide substantial computing power for problems too large to address with a desktop machine. A network attached storage device will promote sharing of common data sets in an efficient manner and provide each department member with a common working directory accessible at very high speed from all machines on the IGPP local area network (LAN). Workstations will provide graduate students with a tool to complete class exercises and initiate thesis research. Overall, addition of these devices will simplify administration of the IGPP LAN and allow overburdened IT professionals to concentrate their efforts on more productive activities. Improving the local infrastructure will immediately provide a more reliable and stable conduit through which outside users can access several facilities at IGPP that are shared and/or accessed by scientists in other departments or at other universities. Key examples include the IRIS/IDA seismic Data Collection Center, the Scripps Orbit and Permanent Array Center, and the SIO Visualization Center. ***
