Enabling Breakthrough Kinetic Simulations of the Magnetosphere via Petascale Computing

该奖项促进了使用IBM开发的名为Blue沃茨的大型新计算资源的科学研究，并计划于2011年在伊利诺伊大学部署。该基金提供差旅费，以支持主要调查人员、蓝色沃茨项目小组和供应商技术小组之间的技术协调，该基金将帮助研究人员编写和开发应用代码，这些代码随后将用于对太阳风与磁层的相互作用进行最准确的全球模拟，远远超过目前的任何模拟。 3D全局模型的准确性和新奇来自其混合方法：流体电子与动力学离子耦合。模拟结果将提供给研究界，从而激发更多的研究问题，了解太阳风与地球磁场的相互作用是了解空间气象的核心。 “空间天气”一词是用来描述影响地球及其技术系统的空间条件的。空间气象影响到以下方面的运行：㈠全球定位系统卫星; ㈡地球同步通信和气象卫星; ㈢地面大规模配电网; ㈣电离层导航和通信系统。

This award facilitates scientific research using the large new computational resource named Blue Waters being developed by IBM and scheduled to be deployed at the University of Illinois in 2011. It provides travel funds to support technical coordination between the principal investigators, the Blue Waters project team and vendor technical team.The award will aid researchers in the preparation and development of application codes which will subsequently be used to carry out the most accurate global simulations of the interaction of solar wind with the magnetosphere, far surpassing anything currently available. The accuracy and novelty of the 3D global model derives from its hybrid approach: fluid electrons coupled with kinetic ions. Results of the simulations will be available to the research community, stimulating additional research questions.Understanding solar wind interaction with the Earth's magnetic field is central to an understanding of space weather. The term "space weather" has been coined to describe the conditions in space that affect the Earth and its technological systems. Space weather affects operations of (i) Global Positioning System satellites, (ii) geosynchronous communication and weather satellites, (iii) large-scale power distribution grids on the ground, and (iv) navigation and communications systems through the ionosphere.
