存在另外一种调度算法:动态调度算法,即任务的优先级不是固定的。文章中的deadline-driven scheduling algorithm是一种动态调度算法,该调度算法的思想:任务的优先级根据其截止时间调整,截止期越近的任务优先级越高,即EDF调度算法。 针对文章中提出的任务集,EDF调度算法可以让所有的任务都被调度,而RM调度算法没法保证。...
In this paper, we propose a two-stage distributed shared memory architecture (TSDSM). The lower bound of it is also given. Scheduling algorithms for a TSDSM imitating a FCFS output-queued (OQ) switch and a FIFO OQ switch are given too. The validities of these algorithms are theoretically...
A major problem with priority-scheduling algorithms is indefinte blockhing(or starvation). In a heavlly loaded computer system, a steady stream of higher-priority processes can prevent a low-priority process from ever getting the CPU. A solution to the problem of indefinite blockage of low-pri...

We qualitatively and quantitatively compare STFM to one new and three previouslyproposed memory access scheduling algorithms, including network fair queueing. Our results show that STFM provides the best fairness, system ...
schedules when there is provision for fault-tolerance. The performance of the solutions proposed is evaluated in terms of the number of processors and the cost of the checkpoints needed. Moreover, analytical studies are used to reveal interesting trade-offs associated with the scheduling algorithms....
OS | Disk Scheduling Algorithms: In this tutorial, we will learn about the various disk scheduling algorithms along with its advantages and disadvantages. By Mahak Jain Last updated : May 07, 2023 Let us compare various disk scheduling algorithms:...
In addition, the online algorithm is at least 90% of the optimal. In terms of scalability, the greedy algorithm (without local search) scales to 10-times more tasks than the incremental MIP and 1000-times more than the static MIP in reasonable time. When taken together, our algorithms and...
