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.

这笔拨款为科罗拉多大学地球物理小组获取多CPU PC集群用于地球动力学/地震学建模提供了部分支持。提议的PC-cluster将用于许多计算密集型的NSF/EAR资助项目，包括1)利用羽流相关观测约束地幔热化学对流（地球动力学），2)岩石圈下小尺度对流和岩石圈演化（地球动力学），3)地幔超长波长结构的形成及其对超大陆形成和分裂的影响（地球动力学），4)环境噪声层析成像（地震学），5)地震结构蒙特卡罗反演和表面波层析成像（地震学）；6)地震波传播正演模拟。PC集群将通过研究和教学帮助科罗拉多大学地球物理组的研究生和博士后在并行计算和编程方面进行培训。研究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免费提供给地球物理界。
