Abstract

This paper introduces compositional performance analysis into evolving organic systems. It presents a layered distributed framework that can follow the platform and system evolution, continuously monitoring the effect of changes in the application on real-time constraints. For that purpose, an existing methodology based on iterative compositional performance analysis was adapted to a distributed algorithm. A buffering strategy is introduced to improve the algorithm convergence to the same order as the existing centralized offline algorithm. The effects are demonstrated in experiments.
