Performance optimization is an issue at different levels, in particular for computing and communication intensive codes like free surface lattice Boltzmann. This method is used to simulate liquid-gas flow phenomena such as bubbly flows and foams. Due to a special treatment of the gas phase, an aggregation of bubble volume data is necessary in every time step. In order to accomplish efficient parallel scaling, the all-to-all communication schemes used up to now had to be replaced with more sophisticated patterns that work in a local vicinity. With this approach, scaling could be improved such that simulation runs on up to 9 152 processor cores are possible with more than 90 Homepage: http://www10.informatik.uni-erlangen.de/de/Research/Projects/walberla/ Related Software: Palabos; OpenLB; Peano; MUPHY; LB3D; p4est; LUDWIG; Gerris; likwid; CUDA; Hemocell; Hemelb; LBcuda; LBsoft; TLBfind; STLBM; COMSOL; Basilisk; oomph-lib; DUNE Cited in: 23 Publications Standard Articles 1 Publication describing the Software, including 1 Publication in zbMATH Year waLBerla: Optimization for itanium-based systems with thousands of processors.
