Facility: Computational Infrastructure for Geodynamics

该合同支持地球动力学计算基础设施（CIG）设施的持续运营，以建立和维持地球动力学和地震学的基本网络基础设施和计算能力。自2005年以来，CIG开发并传播了广泛使用的开源软件，用于计算地震学、地幔对流、岩浆动力学、短期和长期岩石圈变形以及地球动力学建模的研究和教育。CIG通过改进科学软件开发实践和推进数百名地球动力学家的教育，继续塑造计算地球物理学研究的文化。CIG对科学软件开发和传播的方法已经成为地球动力学和相关科学团体不可或缺的一部分，并且包括与计算科学建立和持续的深厚联系。科学计算是固体地球科学不可或缺的一部分，它使我们能够理解和量化不仅塑造而且影响地球可居住性的过程。计算模式在观测和描述地球内部和表面之间的演变和联系以及固体地球过程与大气变化之间的关系的定量模式之间提供了必要的联系。CIG模型还为地质灾害、自然资源和国家安全的应用提供信息。CIG通过支持可持续的软件开发、网络基础设施和人力资源，继续推动地球动力学的前沿研究。在协作社区治理的指导下，CIG重点关注4个基石：1)建模软件：提供强大的软件来解决计算模型，由重要的科学问题驱动，并建立在开源软件和科学计算的最佳实践之上；(2)计算工作流：支持有助于建立、执行、分析和交换复杂计算模型的工作流；(3)培训：使受过良好教育、训练有素和多样化的劳动力能够有效地使用和扩展计算模型，以进行可重复的发现和重用，并能够充分利用高性能计算资源；(4)社区：建立和维持一个多样化和可持续的学科和跨学科研究人员社区，共同研究具有挑战性的地球科学和软件问题。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award supports continued operations of the Computational Infrastructure for Geodynamics (CIG) facility to build and sustain essential cyberinfrastructure and computational capacity for geodynamics and seismology. Since 2005, CIG has developed and disseminated widely used, open-source software for research and education in computational seismology, mantle convection, magma dynamics, short- and long-term lithospheric deformation, and geodynamo modeling. CIG continues to shape the culture of computational geophysics research by improving scientific software development practices and by advancing the education of hundreds of geodynamicists. CIG’s approach toward scientific software development and dissemination has become indispensable to geodynamics and related scientific communities and includes established and sustained deep ties to computational sciences. Scientific computation is integral to solid Earth geosciences, allowing us to understand and quantify the processes that not only shape but also influence the habitability of the Earth. Computational models provide an essential link between observations and quantitative models describing the evolution and connections between the Earth's interior and surface, as well as relationships between solid Earth processes and atmospheric changes. CIG models also inform applications to geohazards, natural resources, and national security.CIG continues to enable frontier research in geodynamics by supporting sustainable software development, cyberinfrastructure, and human resources. Guided by collaborative community governance, CIG focuses on 4 cornerstones: 1) Modeling software: Providing powerful software to solve computational models, motivated by important science questions, and built on best practices in open source software and scientific computing; (2) Computational workflows: supporting workflows that facilitate the set-up, execution, analysis, and exchange of complex computational models; (3) Training: Enabling a well-educated, well-trained, and diverse workforce that can effectively use and extend computational models for reproducible discovery and reuse, and that can fully exploit high-performance computing resources; and (4) Community: Building and sustaining a diverse and sustainable community of disciplinary and interdisciplinary researchers working together on challenging geoscience and software problems.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.
