AB: The computational geospace community have developed a number of different approaches to the modeling of physical phenomena in the near-Earth region. This presentation gives an overview of various physical approximations used to model these phenomena, as well as state-of-the-art computational techniques for their numerical realizations. In particular, we will review most recent advances in adaptive technologies (adaptive mesh refinement, discrete-event simulation) aimed at enabling realistic simulations of multi-scale space plasmas on modern supercomputers. We will also compare different code-code coupling strategies for the efficient synchronization control of the execution and interaction of codes with different physics models and show the need for the development of a 'simulated-time', event-driven operating environment in order to achieve reliable (stable, time-accurate) interoperability of distributed multi-physics applications.
