This list is just a collection of thesis ideas that were already formulated. We always have more interesting ideas, which were not written down yet, on the topics operating systems, real-time systems, dependability, software variability, etc. So, if this list is empty, you find none of the presented thesis ideas interesting, or you have this one brilliant idea you want to pursue, just come around or write a mail.

Design and Prototypical Implementation of a Message-Broker Proxy for Mixed-Criticality Real-Time Systems
Typ: Bachelorarbeit
Status: reserviert
Supervisors: Christian Dietrich
This bachelor thesis aims to design and implement a message-broker proxy for mixed-criticality real-time systems that use a data-centric architecture and UDP for communication. The thesis evaluates different scheduling algorithms that ensure data refreshness and round trip times.

System-call offloading via Linux' io_uring on the Jailhouse partitioning hypervisor
Typ: Bachelorarbeit
Status: abgeschlossen
Supervisors: Christian Dietrich
Bearbeiter: Kelvin Andres Reichenbach (abgegeben: 17. Nov 2021)
Integrate the io_uring asynchronous system-call interface with the partioning hypervisor Jailhouse. Thereby, hypervisor cells are able to offload I/O to the bystanding Linux cell. [PDF]

Primitives and Abstractions for Self-Contained Virtual-Memory Areas in the Linux kernel
Typ: Masterarbeit
Status: abgeschlossen
Supervisors: Christian Dietrich
This thesis implements the basic abstraction for self-contained virtual-address-space areas in Linux, by which we want to ease the allocation, the sharing, and the management of huge amounts of memory.

Pruning of Soft-Error Fault Spaces by Dynamic Register-Usage Tracing in a Formal Instruction-Set Model
Typ: Masterarbeit
Status: abgeschlossen
Supervisors: Christian Dietrich, Daniel Lohmann
Project: CLASSY-FI
[External at Leibniz Universität Hannover] In this thesis, the SAIL compiler should be extended to allow the C-emulator to record all dynamic register reads and writes to these state registers. This information should then be integrated into the FAIL* toolchain to inject only those state registers that are actually used by a given executed instruction.
