Own Projects

ParPerOS: Parallel Persistency OS (DFG: DI 2840/2-1)

In ParPerOS, we examine new abstractions for unified but efficient and optionally crash-consistent low-level memory management for data objects in heterogeneous memory systems that consist of volatile, persistent, distributed and other types of main memory.

ATLAS: Adaptable Thread-Level Address Spaces (DFG: DI 2840/1-1)

In the ATLAS project, we investigate dynamic specialization and containment by means of thread-level address-space variations.

CLASSY-FI: CLASSY-FI: Cross-Layer Application-Specific Synthesis and Analysis of Fault Injection

The goal of the CLASSY-FI project is to derive constructive methods and techniques for scalable, yet precise and complete FI to experimentally assess the robustness of safety-critical embedded control systems against soft errors. The key idea behind the CLASSY-FI method is an application-specific cross-layer data-flow analysis, by which we consider the program–hardware-specific fault-propagation structure systematically on different levels.

Associated Projects

AHA: Automated Hardware Abstraction in Operating-System Engineering

Our goal with AHA (Automated Hardware Abstraction in Operating System Design) is to improve nonfunctional properties of system software by a very deep, but fully automated specialization of the application-hardware bridge represented by the operating system. We want to investigate, how more directly mapped implementation variants of the same OS functionality – which are semantically equivalent (only) for a particular application – can be generated fully automatically from analyzing this application and its specific interactions with the operating system.

CADOS: Configurability-Aware Development of Operating Systems

In the CADOS project, we investigate scalable methods and tools to grasp the variability on every layer within the configuration and implementation space, visualize and analyze it and, if possible, adjust it while maintaining a holistic view on variability.

Past Projects

VAMOS: Variability Management in Operating Systems (DFG SCHR 603/7)

In the VAMOS project, we pioneered the issue of variability-induced issues in Linux and investigated methods and tools to mitigate the problem. Our findings have led to more than 100 accepted patches in the Linux mainline kernel.

danceOS: dependability aspects in embedded Operating Systems (DFG: SPP 1500)

Future hardware designs for embedded systems are expected to exhibit an increasing rate of intermittent and permanent errors in exchange for smaller device sizes and lower energy consumption. The DanceOS project aims at providing dependability by the fine-grained and tailorable application of software-based fault-tolerance techniques.
