Abstract :
In work on globally-scheduled soft real-time multiprocessor systems, analysis has been presented for dealing with self-suspensions, but this analysis can be pessimistic. In this paper, we present an approach that is designed to improve the schedulability of such systems. In experimental results that are presented, the proposed approach significantly improved schedulability in most considered scenarios.
