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.

现今天体物理学的研究主要是基于大型的数值模拟。最近和正在进行的硬件发展清楚地表明，下一代超级计算机将由众核节点主导。其中，最有前途的持久成就将建立在图形处理单元（GPU）上，如今，图形处理单元将500多个计算核心联合收割机在单个GPU上。不幸的是，大多数天体物理软件包还不能利用GPU的能力。在这个项目中，我们将进一步移植我们的磁流体代码FLASH和辐射传输代码PHOENIX，以有效地利用GPU的能力。这些发展将补充最近在汉堡Sternwarte安装的GPU集群和计划在汉堡大学Regionale Rechenzentrum的GPU超级计算机。
