High Performance Computing (HPC) and Clustercomputing

SCC gives KIT users access to High Performance Computing (HPC) and Data Intensive Computing (DIC) infrastructures. SCC itself operates several computer systems (bwUniCluster, ForHLR) for different user groups. In addition, KIT scientists can use the bwForCluster within the framework of the bwHPC federation. The SCC also advises on applications for computing time on supra-regional high-performance computers (Tier-2), such as the ForHLR, or on the national supercomputers (Tier-1) of the Gauss Centre for Supercomputing (JSC, HLRS, LRZ).

The Baden-Württemberg University (or universal) cluster, i.e. bwUniCluster, is a parallel computer with a total of 872 SMP computing nodes and approx. 86 TB main memory. With a theoretical peak performance of approx. 444 TFLOPS, it is the first central system for a comprehensive basic supply of Baden-Württemberg universities and colleges with high-performance computing capacity. As part of the Baden-Württemberg state concept for high performance computing "bwHPC" in research and teaching, the SCC operates this performance level 3 cluster, aiming at jobs running on a smaller amount of nodes and servicing as a system for basic and teaching needs.

In addition to the bwUniCluster basic supply system, there are four high-performance Computing Clusters for research purposes (in short, bwForCluster) at HPC performance level 3 (Tier-3) in Baden-Württemberg, which are used to supply different scientific areas with computing time. Currently, the bwForCluster MLS/WISO in Mannheim/Heidelberg covers scientific projects in the fields of economics and social sciences and the bwForCluster JUSTUS in Ulm covers scientific projects in computer-aided chemistry. From mid-2016 on, the bwForCluster NEMO in Freiburg for scientific projects in neuroscience, microsystems technology and elementary particle physics and the bwForCluster BinAC in Tübingen for scientific projects in bioinformatics and astrophysics will follow.

High Performance Computer for Research Purposes ForHLR (Phase) I and II

Both systems ForHLR I and ForHLR II at SCC, being systems of HPC performance level 2, are directly below the systems of the national High Performance Centers. Both systems were acquired in two phases, both phases together having a total computing power of approx. 1.2 PFLOPS (theoretical peak power) and the ForHLR II is currently the most powerful system at KIT. Together with the second phase  (ForHLR II), a new visualization infrastructure was established. Scientists from all over Germany can gain access to ForHLR I and ForHLR II via project proposals that are reviewed by the HLRS-Steering Committee . The ForHLR II with more than 24,000 nodes is intended for research projects that require parallel computing on very high three-digit and four-digit processor numbers. ForHLR I, on the other hand, is reserved for requirements that are below those for ForHLR II on the one hand and above those for systems at performance level 3 (e.g. bwUniCluster) on the other hand and thus rank in the mid to upper three-digit processor number spectrum.

Scientific Support

An essential task for the SCC is to support the users with their technological and scientific applications which do not only have to be purely within the HPC area. In addition, support and consulting is provided for components of software development such as compilers, debuggers, analysis tools, MPI, etc. as well as for open source codes and numerical libraries. Research-related and research-accompanying support is provided by SimLabs (Simulation Laboratories), which currently cover four research areas: Earth (climate) and Environment, NanoMicro, Energy and Astroparticle Physics. For more information on SimLabs, please visit the Scientific Computing and Simulation Department.

In addition to supporting research and development with hardware, software and many years of know-how in these two areas, teaching in the HPC field and its environment is of equal importance. The page "Teaching, Training and Further Education provides information about offers in the field of teaching.
