项目摘要
NSF PetaApps 0749334/0748898/0749045: Understanding the Dynamics of the Earth: High-Resolution Mantle Convection Simulation on Petascale Computers George Biros (Penn), Omar Ghattas (UT-Austin), Michael Gurnis (CalTech), Shijie Zhong (CU-Boulder) Mantle convection is the principal control on the thermal and geological evolution of the Earth. It is central to our understanding of the origin and evolution of tectonic deformation, the evolution of the thermal and compositional states of the mantle, and ultimately the evolution of the Earth as a whole. Despite its central importance to our understanding of the dynamics of the solid Earth, simulation of global mantle convection at realistic Rayleigh numbers down to the scale of faulted plate boundaries is currently intractable, due to the wide range of time and length scales involved. This project will capitalize on upcoming petascale computing systems to carry out the first high resolution mantle convection simulations that can resolve thermal boundary layers and faulted plate boundaries, which will enable the first inverse solutions that can incorporate historical plate motions. These simulations will lead to breakthroughs in understanding the dynamics of the solid Earth. However, to make effective use of the upcoming petascale systems, new scalable algorithms and implementations are needed. To enable these simulations, this project will: (1) tune, improve the performance of, and scale up to the petascale the parallel open-source mantle convection code CitcomS; (2) develop, implement, robustify, and incorporate new parallel algorithms for adaptive mesh refinement and inverse solution that can scale to hundreds of thousands of processor cores; and (3) release the resulting mantle convection codes to the geosciences community via the Computational Infrastructure for Geodynamics (CIG), an NSF center that develops and maintains software for several earth science communities.
NSF PetaApps 0749334/0748898/0749045:理解地球的动力学:Petascale计算机上的高分辨率地幔对流模拟乔治比罗斯(宾夕法尼亚大学),奥马尔Ghattas(UT-奥斯汀),迈克尔Gurnis(加州理工学院),Shijie Zhong(CU-博尔德)地幔对流是地球热演化和地质演化的主要控制因素。它对于我们理解构造变形的起源和演化、地幔的热状态和成分状态的演化以及最终整个地球的演化至关重要。尽管它的核心重要性,我们了解固体地球的动力学,模拟全球地幔对流在现实的瑞利数下降到规模的断层板块边界目前是棘手的,由于广泛的时间和长度尺度的参与。该项目将利用即将到来的千万亿次计算系统进行第一次高分辨率地幔对流模拟,可以解决热边界层和断层板块边界,这将使第一个逆解,可以纳入历史板块运动。这些模拟将导致在理解固体地球动力学方面的突破。然而,为了有效地利用即将到来的千万亿次系统,需要新的可扩展算法和实现。为了实现这些模拟,该项目将:(1)调整、提高并行开源地幔对流代码CitcomS的性能,并将其扩展到千万亿次;(2)开发、实施、鲁棒化并纳入新的并行算法,用于自适应网格细化和逆解,这些算法可以扩展到数十万个处理器内核;以及(3)通过地球动力学计算基础设施(CIG)向地球科学界发布由此产生的地幔对流代码,CIG是为几个地球科学界开发和维护软件的NSF中心。
