Advanced Computing User Day

Rob van Nieuwpoort

Rob van Nieuwpoort is full professor “Efficient Computing and eScience” at the Leiden Institute of Advanced Computer Science (LIACS) at Leiden university, The Netherlands. His research involves ways in which large-scale computing power can be used more efficiently in achieving scientific breakthroughs in various scientific fields. He develops new programming models that make the use of large-scale systems (so-called exascale computers) simpler and more efficient. In addition, energy efficiency plays a crucial part. For large-scale scientific experiments such as the Square Kilometre Array (SKA) telescope, energy use is a limiting factor and a major expense. In these cases, software that uses energy more efficiently will have the immediate effect of increasing the sensitivity of the instruments. His second research interest is eScience. The field of eScience promotes the use of digital technology in research. eScience brings together IT technology, data science, computational science, e-infrastructure and data- and computation-intensive research across all disciplines, from physics to the humanities. He works on bridging fundamental computer science research and its application in exciting scientific disciplines.

Driving Energy Efficiency in Cloud and Large-Scale Computing for Research
Dr. Serkan Girgin, Sagar Dolas, Adhitya Bhawiyuga, Gijs van den Ooord, Rob van Nieuwpoort, Gilles Tourpe

Energy efficiency in computing becomes more and more important as climate change impacts intensify, energy costs increase, and efforts to reach the Sustainable Development Goals to tackle environmental, social and economic issues gain momentum. This is especially true for large-scale computing for research, including cloud computing, which underpin advancements and breakthroughs in many scientific domains. Achieving significant improvements in energy efficiency for such resource-intensive computing tasks, especially artificial intelligence methods including machine learning, deep learning and the new generation of large language models, is a complex challenge that requires a coordinated effort across hardware and software domains, as well as a large group of actors including infrastructure providers, system administrators, software developers, and researchers. Despite the rapid pace of technological development, many existing tools and platforms still lack essential features, such as detailed energy consumption metrics and granular task-level monitoring capabilities. Optimization of research computing workflows considering energy efficiency is also mostly overlooked. This panel discussion seeks to unite a diverse array of experts from the Netherlands, and potentially from the international community, to shed light on the current practices and challenges of energy-efficient computing, with a special focus on research. We aim to explore how energy efficiency is currently addressed within advanced computing, identify critical gaps, and discuss actionable steps to enhance collaboration and drive forward more energy-efficient practices. By fostering this exchange of ideas and experiences of different actors, we hope to contribute to the development of computing infrastructures and workflows that are not only powerful but also environmentally sustainable.
