Supported by the Strategic Priority Research Program “The Emergence of Cosmological Structures” of the Chinese Academy of Sciences, Grant N XDB09000000. The main part of the simulations presented here was performed on the dedicated GPU clusters kepler at the ARI. funded under the grants 1/80 041-043 and 1/81 396 of the Volkswagen Foundation and the grants 823.219-439/30 and /36 of the Ministry of Science, Research and the Arts of Baden-Wurttemberg, Germany. The authors are acknowledges the support of the Volkswagen Foundation under the Trilateral Partnerships grant No. 90411. Part of the code development work was conducted using the resources of the GPU cluster laohu at the Center of Information and Computing at the National Astronomical Observatories, Chinese Academy of Sciences, funded by the Ministry of Finance of People’s Republic of China under the grant ZDYZ2008-2.
