Upgrade of the UC Berkeley Seismological Laboratory and Geophysics Computer Laboratory Communication Network

9809738 Romanowicz这笔赠款为加州大学伯克利分校的地球物理计算机实验室(GCL)和伯克利地震实验室(BSL)升级以太网网络的费用提供部分支持。一个新的带有相关外围设备的100Base T(100Mbit/S)网络将取代目前的10Base T(10Mbit/S)网络。GCL和BSL为伯克利数字地震台网(BDSN)、湾区区域形变(BARD)网和由美国地质调查局运营的北加州地震台网(NCSN)提供主要的数据采集和分析基础设施。此外，升级后的网络将允许高带宽连接到一些奔腾台式系统，这些系统最近被授予地质部，作为英特尔更大的UC-Berkeley“千禧”计算机奖的一部分。波特率提高一个数量级将提高PI利用并行处理三维地震衰减和地壳浅层波传播模型的能力，并将通过提供更快速地访问来自BDSN、BARD和NCSN的公开存档数据来服务于更大的地球物理界。***

9809738 Romanowicz This grant provides partial support of the costs of upgrading the Ethernet network for both the Geophysics Computer Lab (GCL) and the Berkeley Seismological Laboratory (BSL) at the University of California at Berkeley. A new 100 Base T (100 Mbits/s) network with associated peripherals will replace the 10 Base T (10 Mbits/s) network currently in place. The GCL and BSL provide the primary data acquisition and analysis infrastructure for the Berkeley Digital Seismographic Network (BDSN), the Bay Area Regional Deformation (BARD) network and data archival for the Northern California Seismic Network (NCSN) operated by the USGS. In addition, the upgraded network will permit high bandwidth connections to a number of Pentium desktop systems that were recently awarded to the Geology Department as part of a larger UC- Berkeley "Millennium" computer award from Intel. An order of magnitude increase in baud rate will improve the PI's abilities to utilize parallel processing for 3-D seismic attenuation and shallow crustal wave propagation models and will serve the greater geophysics community by providing more rapid access to publicly archived data from the BDSN, BARD and the NCSN. ***
