Founded in 1829, the foremost aim of the University of Stuttgart (USTUTT) in research and teaching lies in the fields of engineering and the natural sciences. The university with its 140 institutes distributed over 10 faculties, 5,000 employees, and about 16,000 students has a strong impact in Baden-Württemberg, Germany’s traditional high-tech region.

USTUTT is participating in CRESTA with two institutes –HLRS and IHS.

The High Performance Computing Centre (HLRS) is a research and service institution affiliated to the Information Centre of the University of Stuttgart (USTUTT). It is one of the three national supercomputing centres in Germany and one of the three members of the GAUSS centre for supercomputing, offering services to users from academia and as one of the few in the world also to industry. HLRS world leading experience in supporting users from the engineering domain at large in parallel programming (for example inside the Teraflop Workbench) over the last 20 years, the development of productivity tools for parallel programming including integrated development environments and the expertise in applying software engineering methods to the HPC domain is the basis for the contribution to CRESTA. HLRS is participating in a number of European collaborative supercomputing initiatives, such as Partnership for Advanced Supercomputing in Europe (PRACE), or Distributed European Infrastructure for Supercomputing Applications (DEISA) and its forthcoming successors as well as other infrastructure project such as DORII, BonFIRE and HPC-Europa as well as more than a dozen projects investigating the challenges of future hardware architectures.

The Institute of Fluid Mechanics and Hydraulic Machinery (IHS) of University of Stuttgart has a long tradition in CFD on high performance computers for the flow in hydraulic machinery. For more than 20 years the institute developed an in-house CFD code and recently applies OpenFOAM and is also involved in the development of OpenFOAM. The main research areas in CFD are: unsteady vortex movement, flow instabilities, turbulence modelling, cavitating flows and fluid structure interaction.
