DEBS 2024 Conference

Last week I visited the 18th Conference on Distributed and Event Based Systems (DEBS) in Lyon. Our research team has been very active in the topics of DEBS for many years as well as contributed to the organization of many instances of DEBS in the past.

Overall, this years edition showed that there is still a very active community. I enjoyed very good talks and papers on topics covering a wide range of topics related to distributed data and event processing, such as fundamentals, systems aspects, and programming paradigms. The research program, keynotes and tutorials presented covered deep insights into recent developments of data stream processing systems and data processing applications such as IoT and the DEBS Grand Challenge competition. 

Congratulations to the winners of the DEBS 10 Years Test of Time Award to Thomas Heinze, Zbigniew Jerzak, Gregor Hackenbroich, and Christof Fetzer for their work on “Latency-aware elastic scaling for distributed data stream processing systems.”

Thanks a lot, to the organizing team around Riccardo Tommasini, Angela Bonifati, Tillmann Rabl and Avrilia Floratou.  Looking forward to another edition organized by Vincenzo Gulisano and Marina Papatriantafilou in Gothenburg, Sweden in June 10-13, 2025. 

Finally, I would like to share some recent works of our team covering serveal interesting research directions in the context of DEBS.

HotNets presentation: Towards analog Networking with PCAM

Yesterday (Nov 29), I had the pleasure to present at the ACM Workshop on hot topics in networking (HotNets) how analog components, in particular memristors, can improve energie efficiency and expressiveness of current packet processing architectures. We propose a new programming abstraction named PCAM which accounts in contrast to TCAM memory for the analog nature memristive components.   The work has been conducted in the context of the CogniGron research center. More details, on the paper “The Future is Analog: Energy-Efficient Cognitive Network Functions over Memristor-Based Analog Computations” you can find in the ACM digital library. Special congratulations to Saad Saleh for doing a great job in developing and evaluating PCAM! Finally, thanks to the HotNets organizers for a great event with many exciting propositions for future networking research.

Inaugural Lecture on In-Network Computing by Boris Koldehofe at TU Ilmenau

After being officially welcomed at TU Ilmenau, Boris Koldehofe gave his inaugural lecture at TU Ilmenau on Nov 1st 2023. In his talk named “Accelerating the performance of data driven applications with in-network computing” he discussed how advances in programmable networks can aid to accelerate data-intensive applications in form of in-network computing. Besides discussing technical solutions and research challenges he highlighted also recent research towards energy-efficient in-network computing architectures.
