Upgrading of Linux Computing Facility for Research in Climate-Change, Glacier Dynamics, and Fluid Flow

0447235 Anandakrishnan这笔赠款支持升级目前基于Sun Solaris OS的计算设施，由Sridhar Anandakrishnan、Richard Alley、Peter Flemings和他们在宾夕法尼亚大学地球科学系的学生共享。要购买的特定设备包括10台戴尔工作站，配备双2.8 GHz CPU、3 GB RAM和运行Linux操作系统。其中四个工作站将配备用于可视化的双显示器。这些工作站将取代现有的Sun Ultra 5和Ultra 10工作站，CPU时钟速度在300至440 MHz之间。新的工作站席位仍将利用现有的后台办公室，包括一台Sun文件服务器、多CPU应用程序和计算机服务器以及绘图设备。此外，现有的100Mbit网络交换机将被一台快速Gbit交换机取代。升级后的计算设施将从事各种密集的数值研究工作，从南极大陆冰川的动力学和地震调查到南极地壳和上地幔结构的地震调查，再到被动大陆边缘沉积盆地内的流体流动和压力研究。***

0447235AnandakrishnanThis grant supports an upgrade to a current Sun Solaris OS-based computational facility shared by Sridhar Anandakrishnan, Richard Alley, Peter Flemings and their students in the Department of Geosciences at Penn Sate University. Specific equipment to be purchased includes 10 Dell workstations with dual 2.8 GHz CPUs, 3 Gb RAM and running Linux OS. Four of these workstations will be equipped with dual monitors for visualization. The workstations will replace existing Sun Ultra 5 and Ultra 10 workstations with CPU clock speeds at 300 to 440 MHz. The new workstation seats will still take advantge an existing back office consisting of a Sun File server, multi-CPU application and compute servers and plotting equipment. In addition, the existing network switch at 100Mbit will be replaced with a fast Gbit switch. The upgraded computational facilities will be engaged in a variety of numerically intensive research efforts ranging from dynamical and seismic investigations of Antarctic continental glaciers to seismic investigations of the Antarctic crustal and upper mantle structure to studies of fluid flow and pressures within passive continental margin sedimentary basins. ***
