|The cluster AURORA consists of 72 IBM x335 nodes, each
with two Pentium IV Nocona 3.6 GHz processors and 4 GB of memory.
In total it comprises 144 processors and 288 GB of RAM.
The 72 nodes are interconnected by an Ethernet network and a high-speed
The Red Hat Linux is used as operating system.
This cluster has been purchased in the context of the AURORA project (1997-2007). The AURORA project, which has been led by our Research Group, was an interdisciplinary project that involved several institutes from the University of Vienna and the Vienna University of Technology. The cluster is administered by the staff of our Research Group, but it is located at the Vienna University of Technology. It has been put into service in April 2005.
