OS | Disk Scheduling Algorithms: In this tutorial, we will learn about the various disk scheduling algorithms along with its advantages and disadvantages.ByMahak JainLast updated : May 07, 2023 Let us compare various disk scheduling algorithms: ...
This paper presents a new operating system (OS) scheduling optimization to reduce the impact of such remote memory accesses. By observing the pattern of local and remote DRAM accesses for every thread in each scheduling quantum and applying different algorithms, we come up with a new schedule of...
Multiple queues are maintained for processes with common characteristics. Each queue can have its own scheduling algorithms. Priorities are assigned to each queue. For example, CPU-bound jobs can be scheduled in one queue and all I/O-bound jobs in another queue. The Process Scheduler then altern...
The first and the second steps are the tricky ones. Using purelyrandom solutionswill take a long time to find any optimal solution, which is why OptaPlannersupports multiple optimization algorithms, such as simulated annealing or tabu search. Simulated annealinglooks for solutions that are similar to...

New improved optimal algorithms are presented that can solve these problems in at most O( n log n) time, where n is the number of tasks. The existing algorithms solve most of these problems in O( n 3 ) time. Proofs of optimality of the present algorithms are included, and simple ...
The scheduling algorithms SCT-MAC and OSC-MAC proposed in [44,45] for multi-hop networks both have pipelining and orthogonality features, wherein interfering nodes’ schedules are non-overlapping with each other, and schedules of nodes along a primary route towards the Sink are cyclically ...
