Numerical modeling of atmospheric turbulence over topography
Prof. Ivana Stiperski, Uni Innsbruck
HS - Technik

6020 Innsbruck
17:00 - 19:00
Abstract
In atmospheric sciences, turbulence plays a crucial role as the main mechanism of exchange and transport of energy, momentum and mass between the earth’s surface and the overlying atmosphere, influencing all atmospheric phenomena from smallest scale processes that govern minimum nighttime temperatures (important for road safety and agriculture) to largest scales such as climate. Accurate numerical modelling of turbulence, however, presents a special set of challenges, due to the non-linear and multiscale nature of turbulence. Different numerical approaches are therefore employed, however, all with their own advantages and drawbacks. Modelling turbulence over topography, adds additional challenges associated with non-flat boundaries and the challenge of keeping the flow turbulent within the domain. In this talk I will highlight the different numerical approaches and their challenges, and potential solutions for simulating highly accurate turbulent flow over topography.
Ivana Stiperski was born in 1980 in Zagreb, Croatia. She studied Physics/Geophysics with the focus on the physics of atmosphere and ocean, at the University of Zagreb, where she completed her doctorate in 2010. One year later, she moved to the University of Innsbruck and worked in the group of Mathias Rotach on mountainous boundary layers. Stiperski has received numerous international awards and scholarships, including a Hertha Firnberg Fellowship from the FWF and the Mountain Meteorology Outstanding Early Career Award from the American Meteorological Society. In March 2019, she was appointed to an Ingeborg Hochmair Women's Professorship at the Institute of Atmospheric and Cryospheric Sciences at the University of Innsbruck. Ivana Stiperski received an ERC Consolidator Grant in 2020, one of the most highly endowed scientific awards.
High Performance Models, Methods and Computing - from Basics to Applications in Medicine, Natural Sciences and Engineering
Prof. Dr.-Ing. Wolfgang A. Wall, TUM
HSB 1 - Technik
6020 Innsbruck
17:00 - 19:00
Abstract
Scientific Computing is meanwhile widely acknowledged as the third pillar of scientific discovery and also an essential every day tool in many industries. However, besides impressive growth rates, both on the academic and the commercial side, the full potential of it is not nearly revealed yet. A key to unchain the full potential is to combine all the relevant building blocks at the best possible level - the art of modeling, the development of computational methods as well as the appropriate implementation ready for the best HPC platforms. This talk will try to showcase that such a combination can create game changers in different fields in Science and Engineering and can even lead to a paradigm-shift in health care.
Wolfgang A. Wall is full Professor and founding Director of the Institute for Computational Mechanics at the Technical University of Munich, Germany. Born near Salzburg (Austria), he studied at the University of Innsbruck and received his PhD from the University of Stuttgart. Among others, he acted as founding director of the Munich School of Engineering and is co-founder of the companies AdCo EngineeringGW and Ebenbuild GmbH. Wolfgang A. Wall has received several esteemed awards, is a recent recipient of an ERC Advanced Grant and serves on a large number of prestigious boards. He currently also serves as Rector of the International Centre for Mechanical Sciences (CISM) in Udine (Italy) and is member of the Austrian Academy of Sciences as well as of the Bavarian Academy of Sciences and Humanities.
Powering the Future: Tackling Energy Challenges in Supercomputing and AI
Prof. Dr. Dieter Kranzlmüller, LMU Munich
AULA
6020 Innsbruck
18:00 - 20:00
Abstract
Recent performance gains in supercomputing are being outpaced by soaring power consumption, especially in leadership-class supercomputers. AI infrastructures face similar challenges, with large language models driving energy demands to critical levels. In response, data centers are expanding their power and cooling capacities, adding further to their global environmental footprint. The need for improved energy efficiency in computing has never been more urgent. Have we already reached a critical tipping point, or can innovation drive a more sustainable future? This talk explores the latest advances and examines strategies for balancing the growing energy demands of advanced computing with environmental responsibility.
