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 Waters的大型新计算资源的科学研究，该资源计划于2011年在伊利诺伊大学部署。它提供旅费以支持主要研究人员、Blue Waters项目团队和供应商技术团队之间的技术协调。该奖项将帮助研究人员准备和开发应用程序代码，这些代码随后将用于执行太阳风与磁层相互作用的最精确的全球模拟，远远超过目前可用的任何方法。三维全局模型的准确性和新颖性源于其混合方法：流体电子与动态离子耦合。模拟的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太空天气的核心。人们创造了“太空天气”一词来描述影响地球及其技术系统的太空条件。空间天气影响(1)全球定位系统卫星、(2)地球同步通信和气象卫星、(3)地面大型配电网和(4)通过电离层的导航和通信系统的运行。

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.
