Christian Godenschwager, Florian Schornbaum, Martin Bauer, Harald Köstler, Ulrich Rüde

Abstract

waLBerla is a massively parallel software framework for simulating complex flows with the lattice Boltzmann method (LBM). Performance and scalability results are presented for SuperMUC, the world's fastest x86-based supercomputer ranked number 6 on the Top500 list, and JUQUEEN, a Blue Gene/Q system ranked as number 5.
