Johannes Blühdorn, TU Kaiserslautern Title: Automatic Differentiation of Fixed Points Abstract: In the context of automatic differentiation, special care must be taken when differentiating code that incorporates a fixed point iteration. The memory consumption due to taping for the reverse … Continue reading →

Johannes Blühdorn, TU Kaiserslautern Title: Efficient Solution of the Unit Cell Problem Abstract: For materials with complex microstructure, analytical descriptions of the effective (macroscopic) behaviour are usually not available. In the context of mathematical homogenization, the effective behaviour is approximated … Continue reading →

Falco Schneider, ITWM Title: Speed Limit and Ramp Meter Control for Traffic Flow Networks Abstract: Within the scope of autonomous driving, optimal traffic control yields a possible application by metering the traffic to increase the efficiency of the traffic flow. … Continue reading →

Max Stein, TU Kaiserslautern Title: GPU accelerated AD for a financial application Abstract: Pricing call options using Monte Carlo simulation is massively parallel and hence very well suited for GPU acceleration, where one might wonder if this is also the … Continue reading →

Prof. Dr. Claudia Schillings, Institut für Mathematik, Universität Mannheim Title: Uncertainty Quantification for Inverse Problems Abstract: Uncertainty Quantification (UQ) is an interesting, fast growing research area aimed at developing methods to address the impact of parameter, data and model uncertainty … Continue reading →

Title: Selected shape optimization problems from industry and how to solve them with modern HPC techniques In this talk we like to give a small insight into shape optimization problems from industry that we were involved in the last couple … Continue reading →

Max Sagebaum, SciComp Title: Overview and introduction to MeDiPack Abstract: The correct Algorithmic Differentiation (AD) of message passing is by itself straight forward. Nevertheless, the handling of the different concepts in MPI like asynchronous request or collective communication and the … Continue reading →

Dr. Stefan Görtz, Institut für Aerodynamik und Strömungstechnik, DLR Braunschweig Title: Surrogate and Reduced-Order Models for Use in Aerodynamic Applications, MDO and Robust Design Abstract: Reduced Order Models (ROMs) have found widespread application in fluid dynamics and aerodynamics. In their … Continue reading →
