Science and engineering rely increasingly on computer simulation as a
universal methodology. This simulation based engineering must be founded on
solid physical principles, well-designed mathematical models, and the
skilful use of modern computer technology. In this talk I will illustrate
the potential of advanced simulation methods with examples taken from finite
element computations and flow simulation. The software has been designed and
implemented carefully to support parallel scalability. I will report
scalability tests on very large systems, such as the HLRB-II at LRZ in
Garching, an SGI Altix with almost ten thousand compute cores. More
recently, we have been able to explore the parallel behavior on an IBM Blue
Gene, the JUGENE system at Jülich with more than hundred thousand processor
cores.
