Abstract

Real-time systems seek to guarantee predictable run-time behaviour to ensure that tasks will meet their deadlines. Optimal scheduling decisions, however, easily impose unacceptable run-time costs for many but the most basic scheduling problems, specifically in the context of multiprocessors and distributed systems. Deriving suitable heuristics then usually requires extensive simulations to gain confidence in the chosen approach. In this paper we therefore present Fortissimo, an open framework that facilitates the development of taylor-made real-time scheduling simulators for Multiprocessor systems.
