PBS: A Unified Priority-Based CPU Scheduler

Feng, Hanhua; Misra, Vishal; Rubenstein, Daniel Stuart

A novel CPU scheduling policy is designed and implemented. It is a configurable policy in the sense that a tunable parameter is provided to change its behavior. With different settings of the parameter, this policy can emulate the first-come first-serve, the processing sharing, or the feedback policies, as well as different levels of their mixtures. This policy is implemented in the Linux kernel as a replacement of the default scheduler. The drastic changes of behaviors as the parameter changes are analyzed and simulated. Its performance is measured with the real systems by the workload generators and benchmarks.
