Upgrade of the CERI Student Computing Laboratory

0949319威瑟斯这笔赠款支持在孟菲斯大学地震研究和信息中心（CERI）的学生研究计算设施的升级。 具体采购的设备包括：1）一台配备12 GB RAM和4 TB RAID 5磁盘存储的苹果双四核Xserver; 2）10台苹果MacPro工作站; 3）一台14 TB文件服务器; 4）4台苹果iMac。 CERI现有一个与UNIX网络信息服务（NIS）和网络文件系统（NFS）协议互连的Sun/Solaris网络，一个与Microsoft Active Directory（AD）网络服务互连的PC/XP网络，以及一个未正式互连的Apple/OSX网络。新的苹果硬件和软件将允许使用包括NIS和NFS在内的标准UNIX工具在MacOSX和Solaris网络之间实现完全连接。 学生计算设施升级将使CERI的计算资源与教师计算资源同质化，从而简化系统管理。 这些设备将支持学生和专业人员进行研究，这些研究依靠地震和全球定位系统大地测量观测来研究地壳结构和岩石圈动力学。 目前，国家科学基金会支持的研究范围从美国中部大陆到南极洲，都准备在地球仪调查稀少的地区推进对地壳结构的理解。南极洲），了解冰冻圈和水文负荷对巴塔哥尼亚地壳的影响，并通过推断地壳和上地幔流变学，提高我们对密西西比河流域地震灾害和相关减灾战略的认识。 计算设备将由两名现有的全职系统管理员提供支持。 这些设备将支持两名职业女性地球科学家的研究和研究培训目标。

0949319WithersThis grant supports upgrade of the student research computational facilities at the Center for Earthquake Research and Information (CERI) at the University of Memphis. Specific equipment to be acquired includes: 1) an Apple dual quadcore Xserver with 12GB of RAM and 4TB of RAID5 disk storage; 2) 10 Apple MacPro workstations; 3) a 14 Tb file server; and 4) 4 Apple iMacs. CERI has an existing a Sun/Solaris network interconnected with UNIX Network Information Service (NIS) and Network File System (NFS) protocols, a PC/XP network interconnected with Microsoft Active Directory (AD) network services, and an Apple/OSX network that are not formally interconnected. The new Apple hardware and software will allow fully connectivity between the MacOSX and Solaris networks using standard UNIX tools including NIS and NFS. The student computing facilities upgrade will homogenize compute resources at CERI with faculty computational resources thus simplifying systems administration. The equipment will support student and PI research that relies on seismological and GPS geodetic observations for studies of crustal structure and lithospheric dynamics. Currently NSF-supported studies ranging from the U.S. mid-continent to Antarctica are poised to advance understanding of crustal structure in sparsely surveyed areas of the globe (vis. Antarctica), understanding of the effects of cryosphere and hydrological loading on the Patagonian crust and by inference crustal and upper mantle rheology, and improve our appreciation of seismic hazards and related mitigation strategies in the Mississippi River Valley. The computational equipment will be supported by two existing full time systems administrators. The equipment will support the research and research training objectives of two early career female geoscientists.***
