Computational Upgrade for the SOEST Geophysics and Tectonics Group

这项奖励是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。这项提案寻求7万美元的资金，用于购买升级的计算设备，以升级地球物理和构造集团的集群计算设施--2002年通过SOEST和NSF提供资金。目前的计算资源已支持4名PI、13名学生和1名博士后。然而，随着计算需求的增加，新的雇用PI需要升级到新的128处理器集群，每个集群有16个节点，每个节点有两个四核处理器和16 GB RAM。该系统集成了一个高速的节点间通信系统。虽然可供其他人使用，但私人投资机构将是主要用户。所需的计算设备将纳入各种学科，从区域和全球范围的地幔流动建模、高分辨率地震层析成像、三维地震反射处理和综合地球动力学模型。私人投资促进机构概述了具体项目，包括利用有限元分析地幔和岩石圈地球动力学，了解与地幔对流有关的板块构造运动，了解岩石圈应力，动态地形，限制地震各向异性流动，了解从整个地球到厘米尺度的流变学(通过研究颗粒尺寸演变)，对流和地幔融化对大洋玄武岩地球化学的影响，了解大洋中脊的磁性和断裂作用，了解烟柱-海脊相互作用和地球动力学，大洋中脊地震模拟，地幔-板块上涌动力学，以及地壳吸积，地震反射成像。升级后的联网系统将直接支持由私人投资促进机构提供建议的研究生。此外，该集群将被纳入计算科学研究生班。代码开发、模型和数据将通过NSF资助的CIG中心共享。数据和输出将与NSF资助的项目接口，如Markets、Ridge2000、CIG、Earthscope和CSEDI。研究结果将发表在同行评议的文献中。***

This proposal seeks $70K funding to purchase upgraded computing equipment to upgrade the Geophysics and Tectonics group cluster computing facility - funded through SOEST and NSF in 2002. Current computing resources have supported 4 PIs, 13 students and 1 post-doc. However, the new hire PI along with increased computational needs warrants upgrade to a new 128 processor cluster, having 16 nodes each with two quad-core processors and 16 GB RAM. The proposed system integrates a high-speed inter-node communication system. While available to others, the PIs will be the principal users. The requested computing equipment will be incorporated into disciplines ranging from mantle flow modeling at regional and global scales, high-resolution seismic tomography, 3D seismic reflection processing, and integrating geodynamic models. Specific projects are outlined by the PIs and include mantle and lithosphere geodynamics using finite element analysis, plate tectonic motions associated with mantle convection, understanding lithospheric stresses, dynamic topography, constraining seismic anisotropy flow, understanding rheology at scales ranging from whole Earth down to cm scale (by studying grain-size evolution), convection and mantle melting impact on oceanic basalt geochemistry, understanding magnetism and faulting at mid-ocean ridges, understanding plume-ridge interactions and geodynamics, mid-ocean ridge seismic modeling, mantle-plate upwelling dynamics, and crustal accretion, seismic reflection imaging. The upgraded cluster system will directly support graduate students advised by the PIs. In addition, the cluster will be incorporated into a graduate class in computational science. Code developments, models and data will be shared through the NSF-funded CIG center. Data and outputs will be interfaced with NSF-funded programs like Margins, Ridge2000, CIG, Earthscope and CSEDI. Results will be published in peer-reviewed literature. ***
