Extreme scale simulation of coupled multiphysics problems Rüde, Ulrich


Computers will soon reach exascale performance, i.e. the capability to perform more than 10^18 FLOPS. This will e.g. enable flow simulations where many suspended particles can be resolved as geometric objects and the when time evolution is computed coupling the hydrodynamics of the fluid phase with rigid body dynamics. Or, on a larger physical scale, the whole volume of the Earth can be discretized with a global mesh of 1km resolution to simulate Earth mantle dynamics. However, such extreme scale simulations will only be possible with parallel algorithms that can exploit millions of processor cores. In this talk we will report early experience with such massively parallel computations for multiphysics problems.
