Research in astrophysics is nowadays heavily based on large scalenumerical simulations. The recent and ongoing hardware developmentshows clearly that the next generation supercomputer will be dominatedby many-core nodes. Among those, the most promising enduringachievement will be build on graphics processing units (GPUs),which combine these days more than 500 compute cores on a singleGPU. Unfortunately, the most astrophysical software packages are notyet able to utilize the GPU capabilities. In this proposed project wewill further port our version of magneto-hdyrodyamical code FLASH andthe radiation transport code PHOENIX to efficiently utilize thecapabilities of GPUs. These developments will complement the recently installed GPU-cluster at the Hamburger Sternwarte and the planned GPU supercomputerat the Regionale Rechenzentrum of the University of Hamburg.

如今，天体物理学的研究基于大型鳞片模拟。最近和正在进行的硬件开发表清楚地表明，下一代超级计算机将由多核节点主导。其中，最有希望的耐心研究将是建立在图形处理单元（GPU）上，这些日子结合了单个GPU上的500多个计算核心。不幸的是，最多的天体物理软件包是能够利用GPU功能的标题。在这个提议的项目中，We We将进一步移植我们版本的Magneto-HDyroporamical代码闪光灯和辐射传输代码Phoenix，以有效地利用GPU的功能。这些发展将补充汉堡汉堡汉堡公司最近安装的GPU群集和汉堡大学的Reghenzentrum计划的GPU SuperComputerat。
