Deadline Missed? Reflections on Real-Time Systems Research
Abstract: Real-time research provided solid theoretical and practical foundations for the real-time systems we encounter in our daily lives, including many Bosch products. Examples of formally well-defined techniques that have been integrated into practical systems include RMS, PCP, SCHED_DEADLINE, synchronous languages, logical execution time, and others.
However, in recent years, real-time research seems to encounter challenges in keeping pace with the evolution of software stacks, hardware platform capabilities, and functional mechanisms of modern applications. One observation is that the real-time community has continued to invest substantial research efforts in enhancing and extending classical approaches, whose underlying models and assumptions are incompatible with the novel systems and applications currently being developed and deployed in industry. Consequently, it appears that the influence of real-time research on contemporary real-time systems is diminishing, despite the growing need for enhanced trust in these increasingly complex systems.
In this presentation, we address some of the issues and explore the underlying reasons for them. Furthermore, we highlight challenges and research opportunities for the real-time community arising from a paradigm shift in the way intelligent and autonomous systems will be constructed in the future, referred to as “Reliable Distributed Systems (RDS)“.

Biography: Dr. Arne Hamann holds a Ph.D. in Computer Science from the Technical University of Braunschweig, Germany, obtained in 2008. Currently, he serves as the Head of the Department “Advanced Solutions for Intelligent Systems“ within the Division “Advanced Digital and AI Solutions“ at Bosch Research. Additionally, he holds the position of Chief Expert for “Distributed Intelligent Systems“.
Like the Bosch product portfolio his range of activities is broad encompassing complex embedded systems where the interaction between physical processes hardware and software plays a major role through to distributed IoT systems with elements of (edge) cloud computing. In academic settings, he is a member of the editorial board of the ACM journal “Transactions on Cyber Physical Systems“ and actively participates as a program committee member for various international conferences, such as ECRTS, RTSS, RTAS, DAC, ETFA, and ICCPS.
