Abstract

Operating systems have been shown to waste machine resources by leaving cores idle while work is ready to be scheduled. This results in suboptimal performance for user applications, and wasted power. Recent progress in formal verification methods have led to operating systems being proven safe, but operating systems have yet to be proven free of performance bottlenecks. In this paper we instigate the first effort in proving performance properties of operating systems by designing a mul-ticore scheduler that is proven to be work-conserving.
