On January 8, 2024, the public lecture series “Sustainability in Computer Science” focuses on the next topic.

Dieter Kranzlmüller, head of the Leibniz Supercomputing Centre, will give a talk on “More Compute with Less Energy - A Holistic Approach to Sustainability in a Supercomputing Centre”.


The demand for computing is steadily growing, and the surge of artificial intelligence has further increased the need for computing capacities. This is in particular visible in supercomputing centers worldwide, where more computing leads to more electrical power consumption. As a consequence, energy efficiency is not just a nice-to-have option, it is a must-have in order to deliver more performance for simulation and modeling, artificial intelligence and machine learning. The Leibniz Supercomputing Centre (LRZ) is at the forefront of energy efficiency, providing its leadership class systems with direct hot-water cooling. In fact, the holistic approach of LRZ addresses all aspects of energy efficiency, from the point where electrical energy enters the building to the usage of waste heat, and all the future technologies involved in providing energy-to-science.


About Lecture Series “Sustainability in Computer Science”

The Public Lecture Series is the first of its kind in Austria, with all Austrian computer science departments and faculties participating, under the auspices of Informatik Austria. We want to raise awareness for the utmost importance of sustainability in CS, demonstrating research solutions to various problems, and triggering developments for a sustainable future.

The lecture series will be held online every Monday from 17:00-18:00. One hybrid session takes place on January 8, 2024, on-site at TU Wien and online.

Students from participating universities can register to get credits for the series. Please refer to your respective institution for registration.

TU Wien students can register for VU 194.155 “Sustainability in Computer Science” via TISS. Depending on your study program, the lecture series is a free elective or a “Wahlpflichtfach”, please refer to TISS for further information.
