Upgrade of the Geophysical Computing Network at the University of South Carolina

9725735欧文斯这笔赠款提供了南卡罗来纳大学地球物理计算机网络升级费用的部分支持。1990年至1994年间购买的8台现有Sun工作站(SUN SPARC 1‘S、SLC和LX)将升级到Ultra1配置，2台现有服务器升级到Ultra2配置。计算速度和磁盘存储能力的提高将有利于目前在岩石圈地震学、全球定位系统大地测量和地震构造学方面资助和计划的计算密集型研究方案。此外，增加的磁盘存储容量将作为对南卡罗来纳州地震网络的档案支持，该网络由美国地质勘探局和美国能源部-萨凡纳河站点资助，但由南卡罗来纳州地球物理系维护。最近资助的研究(EAR-9706663)将需要最先进的处理能力和大量数据存储，以便根据从临时宽带区域网络收集的数据开发下地幔的地震模型。强大的图形能力将使根据PASSCAL数据推断的坦桑尼亚克拉通岩石圈深层大陆结构的三维地震模型可视化，并根据运动和永久全球定位系统数据计算出中南美洲会聚边缘的地质时间尺度构造运动的实时可视化。***

9725735 Owens This grant provides partial support of the costs of upgrading the University of South Carolina geophysics computer network. Eight existing Sun workstations (SUN SPARC 1's, SLC and LX's) purchased between 1990 and 1994 will be upgraded to Ultra 1 configurations and two existing servers to Ultra 2 configurations. Increased computational speed and disk storage capacity will benefit presently funded and planned computationally intensive research programs in lithospheric seismology, GPS geodesy and seismotectonics. Additionally, increased disk storage capacity will serve as archival support for the South Carolina Seismic Network funded by the USGS and the DOE-Savannah River Site but maintained by South Carolina geophysics faculty. Recently funded research (EAR-9706663) will require state-of-the-art processing power and massive data storage for development of seismic models of the lower mantle based on data collected from temporary broadband regional networks. Powerful graphics capabilities will allow visualization of 3-D seismic models of the deep continental structure of cratonic lithosphere in Tanzania inferred from PASSCAL data and real-time visualization of geological time-scale tectonic motions at convergent margins in Central and South America calculated from campaign and permanent GPS data. ***
