Research

CADOS: Configurability-Aware Development of Operating Systems (DFG: LO 1719/3-1)
In the CADOS project, we investigate scalable methods and tools to deal with the implementation of variability across all implementation layers of modern system software.
Multiverse: While static variability can be completely resolved at compile time, dynamic variation points come at a cost arising from extra tests and branches in the control flow. Multiverse is an approach to handle dynamic variability efficiently by means of binary patching. It provides an extension to the C programming language that enables the developer to express dynamic variability in performance-critical paths. With specially annotated config variables, multiverse can generate multiple versions of a function and dynamically binary patch the running system to use the version of the current configuration. The goal is to narrow the gap between dynamic and static variability by allowing the developer to easily employ run-time configurability at zero or low cost.
