Acquisition of a PC Cluster for Geophysical Modeling

0650957这笔赠款为科罗拉多大学地球物理学小组购买用于地球动力学/地震模拟的多CPU PC集群提供部分支持。拟议的PC-群将用于NSF/EAR资助的一些计算密集型项目，包括1)利用与羽流有关的观测限制热化学地幔对流(地球动力学)，2)石圈下小尺度对流和岩石圈演化(地球动力学)，3)地幔中甚长波长结构的形成及其对超大陆形成和解体的影响(地球动力学)，4)环境噪声层析成像(地震学)，5)地震结构和面波层析成像的蒙特卡罗反演(地震学)，以及6)地震波传播的正演模拟。PC集群将通过研究和教学，帮助科罗拉多大学地球物理学小组的研究生和博士后在并行计算和编程方面进行培训。调查人员积极参与地球物理计算基础设施(CIG)，新开发和增强的软件包将通过CIG向地球物理界免费提供。

0650957ZhongThis grant provides partial support for acquisition of a multi CPU PC cluster for geodynamic/seismological modeling by the geophysics group at the University of Colorado. The proposed PC-cluster will be used for a number of computationally intensive NSF/EAR funded projects including 1) Constraining thermochemical mantle convection using plume-related observations (Geodynamics), 2) Sublithospheric small-scale convection and lithospheric evolution (Geodynamics), 3) Formation of very long-wavelength structure in the mantle and its implications for supercontinent formation and breakup (Geodynamics), 4) Ambient noise tomography (Seismology), 5) Monte-Carlo inversion of seismic structure and surface wave tomography (Seismology), and 6) Forward modeling of seismic wave propagation. The PC cluster will help train graduate students and post-docs in the University of Colorado geophysics group in parallel computing and programming through research and teaching. The investigators are actively involved in the Computational Infrastructure for Geophysics (CIG) and newly developed and enhanced software packages will be made freely available the geophysics community through CIG.
