High Performance Computing with Graphical Processing Units


In time for the 100 year anniversary of the Hamburger Sternwarte, the GOLEM GPU-Cluster enables its theory group to benefit from the use of Graphical Processing Units (GPUs) for high performance astrophysical computing. 

The cluster has been delivered and assembled by SYSGEN in Feb 2012.
