This award will fund the acquisition of compute nodes to add to one of UC Davis' community clusters in order to support both currently funded and future NSF research projects. With this funding, 8 nodes (384 cores) with 128 TB of storage will be added to the community cluster providing computing resources needed to carry out numerical simulations related to several different research projects. The compute nodes will support projects for both current and future graduate and undergraduate students and postdocs conducting research within the Department of Earth and Planetary Sciences. Having direct access to these resources helps students to learn about high performance computing. Numerical simulations are a powerful method for testing hypothesis about how various aspects of subduction occur, including the interplay between dynamics, material properties and mineralogy. This funding will provide the infrastructure needed to conduct models on: 1) currently funded NSF projects including the development of lattice-preferred orientation in subduction zones and its connection to seismic anisotropy and the coupling between, slab and mantle deformation and surface deformation in the present-day Cascadia subduction zone, 2) other current projects on the role of the plate boundary shear zone in controlling trench retreat, and modeling thermal shear instabilities within the deep slab, and 3) planned research projects, including the link between strain-rate variation in subducted lithosphere and the distribution and triggering mechanism for deep earthquakes, the mechanism by which fluids enter the oceanic crust in the bending region of the outer rise, and the interaction between rising mantle plumes and subducting slabs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项将资助收购计算节点，以添加到加州大学戴维斯分校的社区集群之一中，以支持当前资助和未来的NSF研究项目。有了这笔资金，将添加8个带有128 TB存储空间的节点（384个核心），以提供与几个不同研究项目相关的数值模拟所需的计算资源。 计算节点将支持当前和未来的研究生和本科生以及在地球和行星科学系内进行研究的项目。直接访问这些资源有助于学生了解高性能计算。数值模拟是一种关于俯冲如何发生各个方面的测试假设的有力方法，包括动态，材料特性和矿物学之间的相互作用。这项资金将提供开展模型所需的基础设施：1）当前资助的NSF项目，包括俯冲区域中晶格偏爱的取向的发展，以及与地震性各向异性各向异性各向异性的联系以及平板和地幔变形之间的耦合以及当今Cascadia cascadia cascadia shore the traper Remort of Plote and the traper Remort of Plote and the cascad cascad shore the n of COMPORT and the traper Remot and the n of COMPORT of CROMINE的耦合，2） modeling thermal shear instabilities within the deep slab, and 3) planned research projects, including the link between strain-rate variation in subducted lithosphere and the distribution and triggering mechanism for deep earthquakes, the mechanism by which fluids enter the oceanic crust in the bending region of the outer rise, and the interaction between rising mantle plumes and subducting slabs.This award reflects NSF's statutory mission and has been认为值得通过基金会的智力优点和更广泛影响的评论标准来评估值得支持。
