[1]空间气象建模框架为基于物理学的空间气象模拟以及各种空间物理学应用提供了一个高性能的灵活框架。SWMF将日冕、爆发事件发生器、内日球层、太阳高能粒子、全球磁层、内磁层、辐射带、电离层电动力学和高层大气的数值模型集成到一个高性能的耦合模型中。组件可以用替代物理模型表示，并且可以使用组件的任何物理上有意义的子集。组件通过标准化接口耦合到控制模块，并且高效的并行耦合工具包用于组件的成对耦合。组件的执行和并行布局由SWMF控制。支持顺序和并发执行模型。SWMF能够实现单个物理模型无法实现的模拟。在所有耦合组件中使用合理的高空间和时间分辨率，SWMF在大规模并行超级计算机上运行的速度明显快于真实的时间。本文介绍了SWMF的设计和实现以及一些示范性测试。今后的论文将介绍验证（将模型结果与测量结果进行比较）和对具有挑战性的空间气象事件的应用。SWMF公开提供给科学界进行地球物理研究。我们还打算与其他模型开发人员合作扩展SWMF。
[1] The Space Weather Modeling Framework (SWMF) provides a high-performance flexible framework for physics-based space weather simulations, as well as for various space physics applications. The SWMF integrates numerical models of the Solar Corona, Eruptive Event Generator, Inner Heliosphere, Solar Energetic Particles, Global Magnetosphere, Inner Magnetosphere, Radiation Belt, Ionosphere Electrodynamics, and Upper Atmosphere into a high-performance coupled model. The components can be represented with alternative physics models, and any physically meaningful subset of the components can be used. The components are coupled to the control module via standardized interfaces, and an efficient parallel coupling toolkit is used for the pairwise coupling of the components. The execution and parallel layout of the components is controlled by the SWMF. Both sequential and concurrent execution models are supported. The SWMF enables simulations that were not possible with the individual physics models. Using reasonably high spatial and temporal resolutions in all of the coupled components, the SWMF runs significantly faster than real time on massively parallel supercomputers. This paper presents the design and implementation of the SWMF and some demonstrative tests. Future papers will describe validation (comparison of model results with measurements) and applications to challenging space weather events. The SWMF is publicly available to the scientific community for doing geophysical research. We also intend to expand the SWMF in collaboration with other model developers.
