Upgrading of Geophysics Communal Computer Laboratory

这笔拨款将用于支持加州大学洛杉矶分校地球与空间科学系公共地球物理计算机设备的升级。当前的计算设施是基于由Sun Ultra和SPARC工作站组成的老旧（1997年）Solaris环境。一台新的多cpu SunBlade服务器、五台SunBlade工作站和五台运行Linux的PC工作站将扩大这个网络，并将为11位教职员工和他们的学生提供服务。额外的2tb RAID系统将为分析海量地震数据增加显著的额外存储容量。该大学将为部分新设备提供资金，并为地质大楼的以太网连接升级到1gbit容量提供资金。这笔赠款的一部分还将在安装阶段有限地支助一名计算机系统管理员的薪金。这个升级后的设施不仅将满足首席PI艾米丽·布罗茨基（Emily Brodsky）对爆发动力学理论模型的启动需求，还将满足许多其他活跃教员的需求，包括约翰·维达尔（John Vidale）、大卫·杰克逊（David Jackson）、海蒂·休斯顿（Heidi Houston）、保罗·戴维斯（Paul Davis）和约翰·奥诺（John Aurnou）等等。该计算设施的计算速度和存储容量的增加将促进地震地震学、地震层析成像和地球动力学方面的领先研究。该提案的更广泛影响包括多个研究人员及其学生的基础设施发展，以及促进与社会相关的地震减灾工作

0236455BrodskyFunds from this grant will support an upgrade to a communal geophysics computer facility in the Department of Earth & Space Sciences at UCLA. The current computing facility is based on an aging (vintage 1997) Solaris environment consisting of Sun Ultra and SPARC workstations. A new multi-CPU SunBlade server, five SunBlade workstations and five PC workstations running Linux will augment this network and will serve eleven faculty members and their students. An additional 2 TB RAID system will add significant additional storage capacity for analysis of massive seismic data holdings. The University will provide funding for both a portion of the new equipment and also for an upgrade of the Ethernet connection in the Geology building to 1 Gbit capacity. A portion of this grant will also provide limited support for the salary of a computer systems administrator during the installation phase. This upgraded facility will serve not only the startup needs of the lead PI, Emily Brodsky, for her theoretical models of explosive eruption dynamics, but also the needs of many other active faculty members including John Vidale, David Jackson, Heidi Houston , Paul Davis and John Aurnou, to name a few. The increased computational speed and storage capacity of this compute facility will foster leading research in earthquake seismology, seismic tomography and geodynamics. The proposal's broader impacts include both infrastructure development for multiple researchers and their students and the promotion of societally relevant earthquake mitigation efforts.***
