HLRS Presentation at SC 2003 in Phoenix/Arizona

November 15-21, 2003

The High Performance Computing Center Stuttgart (HLRS) is a federal HPC Center in Germany. In addition, together with T-Systems and Porsche, it has formed a company to provide access to supercomputers for research and industry. HLRS has established a distributed working environment for its users to see and use all resources (T3E-512, SX-5/32, SR8000-16) in a seamless way. At SC2003 HLRS will demonstrate its activities in the field of High Performance and Grid Computing. We will show the main building blocks HLRS is working with and how they are working together. Examples from industry include the car and aerospace sector. Scientific research is demonstrated in medicine, biology, chemistry and physics. The results are visualized by our own collaborative visualization tool COVISE. To show the potential of the resulting framework HLRS will integrate computing resources distributed over several continents.

HPC Challenge Award

Together with its international collaborators HLRS participated in the HPC Challenge with a Global Analysis of Arthropod Evolution. This effort received the HPC Challenge Award. More information is provided here .

Scenarios and tools planned for demonstration:

SNL will kindly provide most of the equipment for the HLRS booth #3209. A number of projects are demonstrated that focus on designing and implementing middleware components, on putting them together to create a framework for grid computing and on running applications to exploit the potential of such frameworks.


PACX-MPI (PArallel Computer eXtension) allows to extend the functionality of native MPI implementations to clusters of MPPs and PVPs. PACX-MPI covers the complete MPI1.2 standard.


COVISE (COllaborative VIsualization and Simulation Environment) is a visualization software that was developed in several European projects. It aims to allow distributed visualization, collaborative working and distributed simulation in a HPCN environment.


MARMOT is a MPI debugging and verification tool that aims to increase the portability of MPI programs and to track down bugs like race conditions and deadlocks.

The Grid Configuration Manager is a tool to ease the handling of distributed MPI-applications in Grid environments


The P3T toolkit is a object oriented framework for general particle tracking applications. Examples are Molecular Dynamics, Direct Simulation Monte Carlo or the simulation of sedimenting particles in fluids.



DAMIEN (Distributed Applications and Middleware for Industrial use of European Networks) is one of three European funded Grid-Computing projects. In close cooperation with datagrid and eurogrid it develops and integrates software tools for metacomputing used for industrial codes from aerospace industries.


CROSSGRID is a European R&D project, which aims to develop, implement and exploit new Grid components for interactive compute and data intensive applications like simulation and visualisation for surgical procedures, flooding crisis, team decision support systems, distributed data analysis in high-energy physics, air pollution combined with weather forecasting.


The aim of the GRASP project is to use GRID technology in order to realize current and future ASP business models that integrate distributed and heterogeneous resources.


GeneSyS is an Information Society Project (IST-2001-34162), which aims to define and implement a middleware architecture for generic system supervision.


HPC-Europa is is a consortium of leading HPC infrastructures aiming at the integrated provision of advanced computational services to the European research community working at the forefront of science. The services will be delivered at a large spectrum both in terms of access to HPC systems and provision of a suitable computational environment to allow the European researchers to remain competitive with teams elsewhere in the world. Moreover the JRA and NA actions will contribute to foster a culture of cooperation to generate critical mass for computational activities, to drive new advance in HPC allowing so to better structure the European Research Area.


Blood flow simulation is a project together with the University hospital at Ulm. CT data are created at Ulm and transformed into 3D-representations of arteries. After automatic mesh creation the arterial blood flow is simulated at Stuttgart and the data is prepared for visualization. This will help surgeons to improve the quality of their work.


URANUS (Upwind Algorithm for Nonequilibrium Flows of the University of Stuttgart) has been developed at the IRS to simulate the reentry phase of a reusable space vehicle in a wide altitude velocity range. To compute large 3-D problems the URANUS code was parallelized at HLRS. The parallel multiblock program is able to run on several hundreds of processors and is used as an example application for the metacomputing testbed.



Virvo is an acronym for VIrtual Reality VOlume Rendering. The goal of the Virvo project is interactive direct volume rendering on both desktop computers and in virtual environments.


HLRS will also show the collaboration with the John von Neumann Institute for Computing (NIC) that extends to the collaboration in the field of seamless computing (UNICORE), gigabit networking and common use of software, developed by the two centers.
