This NSF award to Princeton University funds U.S. researchers participating in a project competitively selected by the G8 Research Councils Initiative on Multilateral Research through the Interdisciplinary Program on Application Software towards Exascale Computing for Global Scale Issues. This is a pilot collaboration among the U.S. National Science Foundation, the Canadian National Sciences and Engineering Research Council (NSERC), the French Agence Nationale de la Recherche (ANR), the German Deutsche Forschungsgemeinschaft (DFG), the Japan Society for the Promotion of Science (JSPS), the Russian Foundation for Basic Research (RFBR),and the United Kingdom Research Councils (RC-UK), supporting collaborative research projects selected on a competitive basis that are comprised of researchers from at least three of the partner countries. The primary goal of this international project involving collaborating researchers in three countries is the development of sophisticated 3D seismic imaging tools for the characterization of earthquakes, Earth 'noise', and mapping of Earth's interior on all scales. The research affects the fields of exploration geophysics, regional and global seismology, and even helioseismology. The proposed research ensures that seismologists will be able to effectively and efficiently harness future high performance computers. The project will develop and enhance open-source software for the simulation of 3D seismic wave propagation in acoustic, (an)elastic and poroelastic media on hierarchical computer architectures. These simulations account for heterogeneity in the crust and mantle, topography, anisotropy, attenuation, fluid-solid interactions, self-gravitation, rotation, and the oceans. A major goal is to be able to routinely and efficiently reach a shortest period of 1 s in global simulations, the shortest period signal that propagates across our planet. This NSF award supports the education and training of a postdoc. Software developed during the course of the proposed research period will be made freely available via the Computational Infrastructure for Geodynamics (CIG). The award also supports the further development and enhancement of the southern California and global ShakeMovie web sites.

这项授予普林斯顿大学的NSF奖给美国研究人员资助了一项由G8研究委员会竞争性竞争性的多边研究计划竞争性的项目，该计划通过应用程序软件的跨学科研究计划，旨在用于全球规模问题的Exascale计算。 This is a pilot collaboration among the U.S. National Science Foundation, the Canadian National Sciences and Engineering Research Council (NSERC), the French Agence Nationale de la Recherche (ANR), the German Deutsche Forschungsgemeinschaft (DFG), the Japan Society for the Promotion of Science (JSPS), the Russian Foundation for Basic Research (RFBR),and the United Kingdom Research Councils (RC-UK), supporting协作研究项目以竞争性为基础选择，由至少三个合作伙伴国家的研究人员组成。这个国际项目的主要目标涉及三个国家的合作研究人员，是开发精致的3D地震成像工具，用于表征地震，地球“噪音”和所有规模上地球内部的映射。该研究影响了勘探地球物理，区域和全球地震学甚至气动学的领域。 拟议的研究确保地震学家将能够有效，有效利用未来的高性能计算机。 该项目将开发和增强开源软件，以模拟声学，（AN）层次计算机架构上的弹性和毛弹性介质中的3D地震波传播。 这些模拟解释了地壳和地幔，地形，各向异性，衰减，流体 - 固定相互作用，自我再生，旋转和海洋的异质性。一个主要目标是能够在全球模拟中常规有效地达到1 s的最短时间，这是在我们星球上传播的最短时期信号。该NSF奖支持博士后的教育和培训。在拟议的研究期间开发的软件将通过地球动力学（CIG）的计算基础设施免费提供。该奖项还支持南加州和全球Shakemovie网站的进一步发展和增强。
