The pseudospectral simulations are conducted on the massively parallel Blue Gene/L system. The small amount of memory per core requires a two-dimensional parallelization of the numerical scheme. We report performance and scaling tests on up to 16384 CPUs and present first physical results for the case of convective turbulence.}, identifier = {05503744}, }
