Upgrading the Earthquake Seismology Computing Facility at Penn State

0447173氨这笔拨款支持宾州州立地震计算设施的升级。升级将需要购买一台Apple Macintosh Xserve文件服务器，四个Macintosh双2.5 GHz G5 CPU工作站，每个工作站具有1gb RAM，线性磁带驱动器备份系统和1.75 Tb RAID Apple Xserve大容量存储。升级将促进从老化的Sun文件服务器/工作站网络到基于Apple MAC OS X的计算环境的过渡，这将大大简化系统管理任务，并将PI的Ammon， Richardson， Nyblade和他们的学生目前可用的计算能力提高近四倍。计算密集型研究将立即受到这一升级的影响，包括对西非和南极东西边界地壳和上地幔地震结构的研究、表面波反演、采矿诱发地震活动性的研究、地震重新定位和核爆炸监测

0447173AmmonThis grant supports upgrade of the Penn State Seismological Computing Facility. The upgrade will entail purchase of an Apple Macintosh Xserve file server, four Macintosh dual 2.5 GHz G5 CPU workstations, each with 1 GB RAM, a linear tape drive backup system, and a 1.75 Tb RAID Apple Xserve mass store. The upgrade will foster a transition from an aging Sun file server/workstation network to an Apple MAC OS X based compute environment that will greatly simplify system administration tasks and increase by a factor of nearly four the compute power currently available to PI's Ammon, Richardson, Nyblade, and their students. Compute intensive research that will immediately be impacted by this upgrade include studies of the seismic structure of the crust and upper mantle beneath West Africa and the East-West Antarctic boundary, surface wave inversions, studies of mining induced seismicity, earthquake relocations, and nuclear explosion monitoring.***
