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.

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...

From February 27 to 29, the staff of the Chairs of Computer Science 4 and 16 met for a joint retreat at Kloster Schwanberg. The participants presented insights into their past year and their research work. The topics were discussed in group and new ideas were generated. The days were rounded off ...

Just before Christmas, on Wednesday, December 20th, Michael Eischer successfully defended his dissertation Geo-Replicated Byzantine Fault-Tolerant State-Machine Replication with Low Latency on the reduction of latency and latency variants of Byzantine fault-tolerant (BFT) systems in a geo-replicated...

On Tuesday, December 5, students and staff met up with their partners for a Christmas party at the Aquarium. The past year was reviewed in a convivial atmosphere with excellent dishes and desserts as well as the usual hot drinks for this time of year. The evening was rounded off, in keeping with tr...
