In multiprocessor systems, a reasonable goal of the sched-uler is to keep all processors as busy as possible. One technique for doing this is to allocate all available processors to the jobs waiting for service. Techniques which allocate all available processors are known as work-conserving policies. In this paper, non-work-conserving policies are examined. These policies keep some number of pr...

Unfortunately, ecotourism is limited in size, and supply-sided measures implicitly contradict the short-term aim of profit-maximizat...

In this paper, we present Deadline Fair Scheduling (DFS), a proportionate-fair CPU scheduling algorithm for multiprocessor servers. A particular focus of our work is to investigate practical issues in instantiating proportionatefair (P-fair) schedulers into conventional operating systems. We show via a simulation study that characteristics of conventional operating systems such as the asynchron...
