Established in 1972, managed from 2002 in the second generation until the end of September 2023 and now in the third generation since October 2023, the chair Department of Computer Science 4 deals with fundamental issues relating to the complexes of system software that supports programs or applications and facilitates the programming or operation of computing systems, monitors and controls the execution of programs, operates computing systems reliably and efficiently in a specific manner and implements an abstract machine with all these characteristics — a layer of software, commonly referred to as the operating system or middleware. In this sense, teaching and research at the chair is generally geared towards a resource-aware systems programming in terms of space, time and energy for stationary, mobile, embedded or centralized or distributed systems, whose individual nodes are typically parallel computing systems in the form of multi- or many-core systems.

From May 13th to May 16th a number of conferences and workshops took place during the Cyper-Physical Systems and Internet of Things Week (CPS-IoT Week) in Hong Kong. This included the 30th IEEE Real-Time and Embedded Technology and Applications Symposium (RTAS), where our colleague Harald Böhm prese...

A group from our chair attended the Eurosys 2024 in Athens from April 22 to 25. The largest European conference on system software once again covered a wide variety of topics, ranging from networking, storage systems, distributed systems, compilers, scheduling, to many papers on or using machine lea...

Signe Schwarz-Rüsch successfully defended her dissertation Blockchain-Based Architectures for Decentralized Data Access. Before joining the i4, Signe worked as research assistant at the Institute of Operating Systems and Computer Networks at the TU Braunschweig. Besides her doctoral superviso...

On March 14 and 15, Timo Hönig (Ruhr Universität Bochum) and Peter Ulbrich (TU Dortmund) jointly hosted this year's spring meeting of the Operating-Systems Special-Interest Group in Bochum. Under the motto Betriebssysteme im Revier, current developments in the operating systems community in Germany...

On March 7, Tobias Langer successfully defended his dissertation Software-based Memory Consistency Mechanisms for Non-Coherent Many-Core Systems, which he wrote as part of the Transregional Collaborative Research Center Invasive Computing. In addition to his doctoral supervisor Prof. Dr. Wolfgang Sc...
