AWI is one of the four shareholders of the German Climate Computing Centre DKRZ in Hamburg (www.dkrz.de). DKRZ is the national german service center for climate researchers and provides high performance computing and data storage infrastructure for basic as well as applied research in the field of climatology and related disciplines. Currently, two computing systems are available: The first one is a vector computer NEC SX6 with 24 nodes each with 8 CPUs and 64 GB memory interconnected by a Crossbar Switch. The second is a SUN linux cluster with 256 dual core nodes.

AWI has an contingent of 4,5 % of the compute time. Up to now, 13 projects from AWI are defined at DKRZ (see table 1). The internal distribution of resources between these projects is coordinated by Bernadette Fritzsch (Bernadette.Fritzsch(at)awi.de). She could also be contacted, if scientists plan to start a new project at DKRZ.
