Performance Awareness in Component Systems: Vision Paper

Resource awareness is a key requirement for dynamic adaptation in resource-constrained systems. Achieving resource awareness with clean separation of concerns and reasonable overhead is still a challenge - especially where this awareness concerns runtime performance. Among the difficult issues are for example transparent performance monitoring or platform independent performance evaluation. To advance the current state of the art in resource awareness, we propose a performance awareness framework for the domain of component-based systems. The framework is based on the Stochastic Performance Logic (SPL), which enables explicit description and automatic evaluation of assumptions about performance using logic formulas. We demonstrate the potential of the framework on multiple use-cases and outline extensions that facilitate the runtime resource awareness.
