在本文中，我们为实时多处理器平台上改变任务的处理器份额（一个被称为重新加权的过程）开发了一个自适应调度框架。我们特别关注的是部署在任务可能频繁需要大幅改变份额的环境中的自适应框架。先前关于在多处理器上实现实时适应性的工作完全集中在能够实施所需适应性的调度算法上。本文提出的算法使用反馈和优化技术在运行时确定需要哪些适应性调整。
In this paper, we develop an adaptive scheduling framework for changing the processor shares of tasks - a process called reweighting - on real-time multiprocessor platforms. Our particular focus is adaptive frameworks that are deployed in environments in which tasks may frequently require significant share changes. Prior work on enabling real-time adaptivity on multiprocessors has focused exclusively on scheduling algorithms that can enact needed adaptations. The algorithm proposed in this paper uses both feedback and optimization techniques to determine at runtime which adaptations are needed.
