Colloquium - Rüde

Parallel Numerical Algorithms for Finite Elements and Flow Simulation
Universität Erlangen-Nürnberg

Large scale numerical simulation requires that we exploit parallelism on all levels. High performance computers will continue to be built as parallel systems with physically distributed memory, but each node will be have processors, each of which will contain many cores. Additionally each core may rely on vectorization. Such systems can provide enormous compute power, but they may require a special programming and a new design of the algorithms. The multigrid finite element solvers HHG developed at Erlangen have been run on up to ten thousand processor cores, solving systems with three hundred billion unknowns. As a second example, the talk will report on the Walberla software framework that is being developed for parallel computational fluid dynamics using on the Lattice Boltzmann method.

This talk is sponsored by the National Center for Atmospheric Research Computational & Information Systems Laboratory and will be held in the Main Seminar Room at the Mesa Lab.
