提出了一种面向实时多核虚拟化的整体多资源分配框架vC2M。vC2M将共享缓存分配和内存带宽调节集成在一起,减少并发任务之间的干扰,从而在任务和虚拟机之间提供更好的时间隔离。它通过任务和VCPU释放同步以及VCPU执行规则来减少抽象开销,并进一步引入了新的资源分配算法,该算法将CPU、缓存和内存带宽一起考虑以优化资源。对我们原型的评估表明,vC2M可以以最小的开销实现,并且与现有解决方案相比,它大大提高了可调度性。
This paper presents vC2M, a holistic multi-resource allocation framework for real-time multicore virtualization. vC2M integrates shared cache allocation with memory bandwidth regulation to mitigate interferences among concurrent tasks, thus providing better timing isolation among tasks and VMs. It reduces the abstraction overhead through task and VCPU release synchronization and through VCPU execution regulation, and it further introduces novel resource allocation algorithms that consider CPU, cache, and memory bandwidth altogether to optimize resources. Evaluations on our prototype show that vC2M can be implemented with minimal overhead, and that it substantially improves schedulability over existing solutions.
