Upgrade of the Computational Facilities in the Geophysics Program at New Mexico State University

[20207495 . cn]该奖项为新墨西哥州立大学固体地球物理项目的计算设施升级提供了部分支持。这次升级使地球物理项目能够跟上计算、网络、安全和存档方面的技术进步。购买一个16节点的Beowulf集群是我们工作的核心。它将以相对低的成本提供高速计算能力。地幔动力学和岩石微观结构演化两个主要项目需要三维平行模拟。目前，这些模拟大多是在校外使用洛斯阿拉莫斯开发的TERRA地幔对流代码和桑迪亚国家实验室开发的蒙特卡罗代码进行的。它们将在贝奥武夫上实现。支持还将用于用更现代的工作站替换我们当前的旧Sun工作站系统。为了满足当今更大的数据量，需要带有RAID阵列和大容量磁带备份的新存储。这些计算机系统将支持位于中国、美国西南部和墨西哥的现场地震学项目的数据存储和分析，并支持地震层析成像和地球动力学项目

0207495HearnThis award provides partial support to upgrade the computational facilities for the solid-earth geophysics program at New Mexico State University. This upgrade enables the geophysics program to stay abreast of technological advances in computing, networking, security, and archiving. Purchasing a 16-node Beowulf cluster is central to our efforts. It will provide high-speed computational power for relatively low-cost. There are two major projects, mantle dynamics and microstructural evolution of rocks, which require three-dimensional parallel simulations. Most of these simulations are currently being done at off-campus sites using the TERRA mantle convection code developed at Los Alamos and a Monte Carlo code developed at Sandia National Laboratories. They will be implemented on the Beowulf. Support will also be used to replace our current system of older Sun workstations with more modern workstations. New storage with a RAID array and large-volume tape backup are needed for today's larger data volumes. These computer systems will support data storage and analysis from field seismology projects located in China, the southwest U.S., and Mexico, and to support projects in seismic tomography and geodynamics.***
