Talk Abstract: Exploiting heterogeneous and hierarchically structured extreme scale computer systems to their full capability requires innovation on many levels: New algorithmic paradigms must address unprecedented levels of concurrency and must support asynchronous execution. A new performance-oriented software design technology must be developed to support efficiency, scalability, portability, and flexibility. I will report on our recent work in the waLBerla and PE frameworks for simulating complex particulate flows based on the lattice Boltzmann method (LBM). Scalability results for up to a trillion lattice cells as well as experiments on accelerator based systems will be presented.
