15:30 Uhr - Daniel Butnaru: Parallelisation of a Multiscale CFD Solver within the Peano Framework (MA)
Modern computational fluid dynamics simulations are faced with an ever increasing need for computing power in fields such as computational steering or weather forecasts. In such important research areas, simulations are limited by the problem sizes which can be handled by single nodes due to their individual performance or memory available. This has made parallelization crucial for simulation codes.
The presentation will deal with a parallel implementation of a fluid solver in the Peano framework. Aspects related to domain partitioning, data dependencies, communication schemes, and framework specifics will be presented. The resulting parallelization is then evaluated in a series of speedup measurements and some PDE specific optimizations are suggested.
