Space Weather Modeling Framework: Modeling the Sun-Earth System Faster Than Real Time
Abstract
The Space Weather Modeling Framework (SWMF) aims at providing a flexible plug-and-play type framework for physics based space weather simulations, as well as for various space physics applications. The SWMF combines numerical models of the Solar Corona (including an Eruptive Event Generator), the Inner Heliosphere, Solar Energetic Particles, Global Magnetosphere, Inner Magnetosphere, Radiation Belt, Ionosphere Electrodynamics and Upper Atmosphere into a high performance coupled model. All the components can be replaced with alternatives, and one can use only a subset of the components. The configuration, compilation and execution of the framework can be done with a user friendly Graphical User Interface. 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 us to do simulations that were not possible with the individual components. Using reasonably high spatial and temporal resolutions in all the coupled components, the SWMF can still run significantly faster than real time on massively parallel super computers. We highlight some numerical simulations obtained with the SWMF.
