Abstract:

Exploiting heterogeneous extreme scale computers to their full capability requires innovation on many levels:
New algorithmic
paradigms must address unprecedented levels of concurrency and must support asynchronous execution.
This talk will report on work for simulating complex flows based on the lattice Boltzmann method (LBM) and on using parallel multigrid methods. A special focus will be on coupled problems as they arise in geophysics and in the numerical simulation of suspensions, where the fluid-structure-interaction between the hydrodynamics and large ensembles of geometrically resolved particles must be modeled and simulated. Validation, scalability and performance results will be presented.
