Title: Affordable and sustainable data- and compute-intensive radio astronomy
By Roelien Attema-Van Waas and Chris Broekema, ASTRON
Abstract: Radio astronomy is a relatively new area of science that relies heavily on the abundant availability of data- and compute-capacity. One could even argue that the advent of affordable compute power, in the form of general purpose mini-computers in the 1970s, made the construction of aperture synthesis arrays like the one in Westerbork possible. More recently, in the early 2000s, ASTRON designed and built the LOFAR telescope to take advantage of the steady increase of available compute power. This is one of the very first 'software telescopes', where a massive amount of complexity is offloaded from the hardware into the software (with all the appropriate growing pains we are only now starting to really understand).

This predictable and inevitable increase in compute capability can no longer be relied upon. Worse, we are now faced with instruments that can produce far more data than we can affordably process. For future telescopes, like the Square Kilometre Array and even more ambitious later telescopes we could easily be overwhelmed by the virtual deluge of data being foisted on the scientist. I this talk we will briefly introduce radioastronomy and the specific R&D challenges and we will go into some detail on the anatomy of a modern large-scale distributed radio telescope, what processing needs to be done with the collected data, and how we are preparing to process the fire-hose of data to be collected by modern instruments. New and emerging technologies play a central role in this strategy.
Short bio Roelien Attema – Head of R&D at ASTRON: Inspired by leading-edge innovation and creating impact in society with new insights and technology she is working the field of applied science for 25 years. Starting at KPN Research, she worked at TNO for almost 20 years in different roles from expert, account manager, project manager to business consultant. Her interest in organisations and people led her to roles in innovation management. She is part of the ASTRON MT and as Head of the R&D department - a group of around 65 professionals covering the full signal processing chain - responsible for all technological innovation within ASTRON. As member of the Board of the Innovation Cluster Drachten she is committed to strengthen the collaboration between industry and academic partners in the North of the Netherlands.

Short bio Chris Broekema: Chris Broekema is a senior research staff member at the Netherlands Institute for Radio Astronomy since 2003. Over the years he has focused most of his work on compute- and data transport hardware design for radio astronomy. He has designed, built, procured, operated and worked on high-performance computing systems for the LOFAR telescope in the Netherlands, including some of the fastest supercomputers in the world at the time, since 2004. More recently his focus shifted to the computational and data-transport challenges in the Square Kilometre Array (SKA), where he was responsible for the hardware platform design of the SKA Science Data Processor (SDP).

To support this work he has done applied research into compute- and data-transport systems. His focus is on the various system aspects that impact the sustainability, suitability and usability of current and emerging compute- and data-transport systems. He has published extensively and defended his PhD thesis on the subject in 2020. He served in various panels and review committees, most notably for the ASKAP science data processor and the ARTS system, and has presented his work numerous times, both nationally and internationally.

Title: Interactive and Connected Battery-Free Systems
By Przemysław Pawełczak, Associate Professor Embedded Systems Group, TU Delft
Abstract: In this talk, I will present some advancements in designing interactive and wirelessly connected ultra-low power, battery-free systems. I will discuss how low-density energy buffers (such as capacitors) and energy harvesting sources - both forming a sustainable alternative to batteries - require a rethink of communication, computation, and interaction paradigms. We will explore these new design paradigms by examining case studies in handheld gaming, electronic prototyping, and low-power wireless networking.
Short bio: Przemysław Pawełczak is an associate professor within the Embedded and Networked Systems Group of TU Delft leading Sustainable Systems Lab. His research vision is to make Internet of Things free from batteries, less polluting and sustainable. With his students Przemysław Pawełczak performs research that is experiment- and systems-oriented (where system is a creation of new hardware and software).

Title: Sustainable Deep Learning: A Systems Perspective
Joint Keynote with NCCV, by Professor Lin Wang, Paderborn University
Abstract: Deep learning (DL) has undeniably revolutionized many fields, but its rapid expansion has put a significant strain on our computing infrastructure. As we celebrate breakthroughs in areas such as computer vision with unprecedentedly large DL models, we must face a stark reality: Our current trajectory is not sustainable. In this talk, I will discuss some of the systems challenges in serving large DL models. In doing so, I will emphasize the critical need for collaboration between deep learning and systems researchers in order to forge a sustainable path forward.
Short bio: Lin Wang is currently a full professor and head of the Computer Networks group at Paderborn University. He received his Ph.D. in Computer Science from the Institute of Computing Technology, Chinese Academy of Sciences in 2015. Before joining Paderborn University, he was a tenured Assistant Professor at Vrije Universiteit Amsterdam and held positions at TU Darmstadt, SnT Luxembourg, and IMDEA Networks Institute. His research focuses on networked systems at the edge and in the cloud, with the goal of achieving efficiency and sustainability. His work has received several awards, including a Google Research Scholar Award, an Outstanding Paper Award from RTSS 2022, Best Paper Awards from IPCCC 2023 and HotPNS 2016, and an Athene Young Investigator Award from TU Darmstadt.
