High Performance Computing at the IWR
IWR is equipped with several small-to-midsize clusters based on x86 architecture. The -by now outdated- cluster "HelicsII" is equipped with 160 nodes with dual core AMD Opteron processors as well as a 10G Myrinet interconnect and was installed in 2007. At that time it was the biggest system at the IWR and the first cluster in Europe with the 10G Myri interconnect. This cluster is still in use for test runs.
Another system consists of 32 AMD Opteron "Bulldozer" processors with 1024 cores and QDR Mellanox Infiniband interconnect. A new and much bigger system is planned for 2015 (within the context of "bwHPC", the concept for high performance computing of the german state of Baden-Württemberg).
The main purpose of these systems is to provide HPC resources to the scientific groups at the IWR for developing new mathematical methods and algorithms.
