SFB 716 Dynamic simulation of systems with large particle numbers

In the special research field 716, researchers from various engineering and natural sciences as well as computer science work on comprehending current scientifically relevant phenomena in simulations on the computer. In doing so they focus on the particles of a system, for example on the individual atoms, molecules or grains of sand and calculate the path of each particle under the influence of its neighbour as well as the forces acting from the outside. Their aim is thereby to observe as high a number of particles as possible over a longer period.

The simulation of such complex multi-particle systems is still a great scientific challenge today from the viewpoint of computer science. In spite of the advances in computer technology, simulations as well as handling and visualising the results continue to reach the limits of that what is currently possible in view of computer performance, memory requirements and broadband.

Computer scientists are therefore developing together with experts from physics, biochemistry, mechanical engineering and process engineering new methods to scale the available computer performance, for example through new programming and modelling approaches as well as new memory and processing strategies. Furthermore, the use of parallel platforms such as graphic cards or many-core chips and new approaches on the efficient analysis of the complex data quantities are being researched.
