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

0207495 Hearing奖为新墨西哥州州立大学的固体地球物理学计划提供部分支持，以升级计算设施。 这次升级使电子物理学计划能够跟上计算，网络，安全和存档方面的技术进步。 购买一个16节点的Beowulf集群是我们努力的核心。 它将以相对较低的成本提供高速计算能力。 地幔动力学和岩石微结构演化是两个需要三维并行模拟的主要研究课题。 这些模拟目前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。 它们将在贝奥武夫号上实施。 还将提供支持，以更现代化的工作站取代我们目前使用的较旧的Sun工作站系统。 对于当今更大的数据量，需要具有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，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.***
