Free-surface flow simulations require high-resolution mesh near the interface and huge computational resource. We develop a simulation method to realize large-scale free-surface flow simulations using the lattice Boltzmann method and multiple GPUs. By using the adaptive mesh refinement (AMR) method which adapts high-resolution grids to the free-surfaces, the number of lattice points can be greatly reduced. In multiple GPU implementation, we use the dynamic domain decomposition method based on the space-filling curve. We demonstrate a large-scale dam-breaking simulation using 64 GPUs on the TSUBAME3.0 supercomputer at the Tokyo Institute of Technology.
