0841794ConradThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). 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. ***

0841794Conrad 该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。该提案寻求 7 万美元资金来购买升级的计算设备，以升级地球物理和构造组集群计算设施 - 2002 年通过 SOEST 和 NSF 资助。当前的计算资源已支持 4 名 PI、13 名学生和 1 名博士后。然而，新聘用的 PI 以及计算需求的增加需要升级到新的 128 个处理器集群，该集群有 16 个节点，每个节点有两个四核处理器和 16 GB RAM。所提出的系统集成了高速节点间通信系统。虽然可供其他人使用，但 PI 将是主要用户。所需的计算设备将被纳入区域和全球尺度的地幔流建模、高分辨率地震层析成像、3D 地震反射处理和集成地球动力学模型等学科。 PI 概述了具体项目，包括使用有限元分析研究地幔和岩石圈地球动力学、与地幔对流相关的板块构造运动、了解岩石圈应力、动态地形、约束地震各向异性流、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化）、对流和地幔熔融对海洋玄武岩地球化学的影响， 了解大洋中脊的磁性和断层作用、了解羽流-脊相互作用和地球动力学、大洋中脊地震建模、地幔板块上升动力学以及地壳增生、地震反射成像。升级后的集群系统将直接支持PI指导的研究生。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（如 Margins、Ridge2000、CIG、Earthscope 和 CSEDI）连接。结果将发表在同行评审的文献中。 ***
