This project is an exploratory activity intended to test the application of new expertise and techniques in performance modeling and optimization to the numerical simulation of earthquakes. It encompasses preliminary work to determine the feasibility of a future effort to develop a petascale version of the Anelastic Wave Modeling (AWM) code that forms part of the Southern California Earthquake Center's community modeling environment. If the AWM and similar models can be adapted to run well on large-scale computational resources, such as forthcoming petascale systems, then it will be possible for researchers to use the model to study the ground motion that would accompany "worst-case" scenarios of earthquakes in Southern California, and elsewhere, resolving frequencies that are important in estimating the damage to built structures. The project is one of a series of pilot projects spawned by a workshop on "Petascale Computing and the Geosciences" in Spring 2006. The purpose of these pilot activities, all related to the use of high-performance computational modeling in different parts of the geosciences, is to determine how the simulation tools used in leading-edge geoscience research can be adapted for the very large-scale computing systems that will be deployed in the next few years. The results of these analyses will be discussed at a second workshop on "Petascale Computing and the Geosciences" in Fall 2006. This SGER project involves collaboration between computer scientists from University of California-San Diego (UCSD), who specialize in the detailed analysis and optimization of numerical applications, and geoscientists from University of Southern California (USC) and San Diego State University (SDSU) who are part of the Southern California Earthquake Center.Broader impacts of this work stem from the potential of earthquake modeling on petascale computers to be able to predict the geographic distribution of seismic hazards more accurately than is presently possible.

该项目是一项探索性活动，旨在测试新的专业知识和技术在地震数值模拟性能建模和优化中的应用。 它包括确定未来开发 Petascale 版本的滞弹性波建模 (AWM) 代码的可行性的初步工作，该代码构成南加州地震中心社区建模环境的一部分。 如果 AWM 和类似模型能够在大规模计算资源（例如即将推出的千万亿级系统）上良好运行，那么研究人员就有可能使用该模型来研究伴随“最坏情况”场景的地面运动南加州和其他地方的地震，解析对于估计建筑结构损坏非常重要的频率。 该项目是 2006 年春季“千万亿级计算与地球科学”研讨会催生的一系列试点项目之一。这些试点活动的目的都与高性能计算模型在地球科学不同领域的使用有关。 ，是为了确定前沿地球科学研究中使用的模拟工具如何适应未来几年将部署的超大规模计算系统。 这些分析的结果将在 2006 年秋季举行的第二次“千万亿级计算和地球科学”研讨会上进行讨论。该 SGER 项目涉及来自加州大学圣地亚哥分校 (UCSD) 的计算机科学家之间的合作，他们专门从事详细分析和研究数值应用的优化，以及来自南加州大学 (USC) 和圣地亚哥州立大学 (SDSU) 的地球科学家，他们是南加州地震中心的一部分。这项工作的更广泛影响源于地震建模的潜力千万级计算机能够比目前更准确地预测地震灾害的地理分布。
