Abstract

The Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, will start physics data taking in 2018 and will accumulate 50 ab$^{-1}$ of e$^{+}$e$^{-}$ collision data, about 50 times larger than the data set of the earlier Belle experiment. The computing requirements of Belle II are comparable to those of a run I high-p$_T$ LHC experiment. Computing will make full use of such grids in North America, Asia, Europe, and Australia, and high speed networking. Results of an initial MC simulation campaign with 3 ab$^{-1}$ equivalent luminosity will be described
