On February 1st, Boris Koldehofe was appointed by the president of TU Ilmenau, Prof. Dr. Kai Uwe Sattler, as Professor of the university. He will be heading the Distributed Systems and Operating Group at the Faculty of Computer Science and the Institute of Applied Computer Science. Boris Koldehofe will continue to collaborate with the University of Groningen and remains a TU Darmstadt fellow as part of the CRC MAKI.
Saad Saleh presented a novel memory architecture TCAmMCogniGron at the IEEE International Conference on Rebooting Computing, 2022. The proposed architecture TCAmMCogniGron is designed to replace a highly energy intensive memory, named Ternary content addressable memory (TCAM), used in almost all current network switches and routers to store processing rules and forward traffic through the Internet. TCAmMCogniGron enables the general purpose integration of special energy saving materials, named Memristors, which allow to keep the processing rules in form of a state, often represented in form of resistance, and this state is non-volatile. In collaboration with Anouk S. Goossens and Tamalika Banerjee from Zernike Institute for Advanced Materials characteristics of a physical memristor built at the CogniGron research center were studied. The findings demonstrate the high energy efficiency and extreme resiliency of the proposed design. The research concluded that in addition to supporting non-volatile state so-called match and mismatch operations require only about 1–16 femtojoules of energy.

The Rosalind Franklin Fellow program of the University of Groningen has opened several positions as Tenure Track Assistant/Associate Professor for female researchers with three positions at the Bernoulli Institute. One position is dedicated to distributed or network-centric systems research. Candidates with a strong background in this area can apply via the RUG online application portal until Oct 27th 2022.
Saad Saleh presented his research on Memristor-based Cognitive and Energy Efficient In-network computing at the Brainspiration 2022 conference, University of Twente, Netherlands. The conference focused on brain-inspired concepts and materials for information processing.
The motivation for brain-inspired computing emerges from the current generation of computers which huge amounts of energy resources and lack cognitive functionality which is critical for many applications like self-driving cars. In this regard, the CogniGron research center at the University of Groningen has developed materials, called memristors, which consume less energy resources and provide cognitive functionality similar to the human brain. Saad presented the use of these cognitive materials for the Internet components and showed various design models and techniques for incorporating cognitive functionality inside the Internet. Preliminary results have shown promising power consumption statistics of these materials for Internet components requiring little (16 uW during operational mode) to no energy consumption (during standby mode).
The speakers and attendees at the conference included renowned scientists and researchers from academia and industry including Beatriz Noheda (CogniGron), Julie Grollier (Thales), John Paul Strachan (Forschungszentrum Jülich), Abu-Sebastian (IBM), Andrea Liu (UPenn), Wilfred Gerard (UT), Wolfram Pernice (Heidelberg University), and researchers from HP labs (USA), Sandia National Labs (USA), AMOLF (NL).
This research is in collaboration with Anouk Goossens and Tamalika Banerjee from Zernike Institute of Advanced Materials, University of Groningen. For more information about this research, contact Saad Saleh or Boris Koldehofe (Adviser).
Young system researchers, e.g., Ph.D. students and PostDocs, can now apply for the EuroSys 2023 Shadow PC until October 12th.
A Shadow PC is meant to allow young researchers to obtain insight into the review process of major conferences. Typically, the review process of a big conference like EuroSys is rather intransperrant to young researchers. Therefore, it isn’t easy to understand what requires excellent research work to be accepted.
In a shadow PC (shadowing the programm commitee), young researchers actively review the research papers submitted to the conference. In EuroSys, papers submitted to the conference will also be assigned to members of the shadow PC for review with the permission of the authors. In addition, the shadow PC will determine and discuss its own ranking of submitted papers. Although the outcome will and must not impact the decision of the conference program committee, the discussion allows the researchers to obtain in-depth experience in the review process. Moreover, the reviews will also provide, in many cases, additional helpful
feedback to the authors.

More information will be added soon…
