The main work of this paper is in three aspects. Firstly, priority is set for urgent tasks, and non-preemptive priority queues are set on the server side of MEC, so that the average stay time of each priority can be calculated according to the current situation of priority tasks queuing....

This paper analyzes in embedded real-time operating system of μC/OS-II, the shortcomings of achieving the dynamic priority, proposes concepts of the two levels cut-off time and analyzes how to set the two cut-off time and relationship between all of tim
This is used to implement a third form of scheduling called cooperative Thread switching. osStatus osThreadYield(); //switch to next ready to run Thread at the same priority Exercise 10.2: Continued—Creating and Managing Threads In this exercise, we will look at assigning different priorities ...
Non-blocking algorithmshave been a subject of much recent study. But with the exception of single-reader single-writer FIFO queues, we've found them to be complex and error-prone. Starting in Android 4.2, you can find our non-blocking, single-reader/writer classes in these locations: ...
Real-time scheduling algorithms are usually only available in the kernels of real-time operating systems, and not in more general purpose operating systems... B Adelberg,H Garcia-Molina,B Kao - IEEE 被引量: 68发表: 2002年 Integrating Priority with Share in the Priority-Based Weighted Fair Que...
Over this baseline, different algorithms have been developed such as resource reservations [3], budget scheduling [4], [5], [6], or constant bandwidth servers [7], [8]. Other solutions introduce extra intelligence over the basic primitives of an RTOS in the form of a quality of service ...
In this work, we consider both fixed and dynamic priority scheduling algorithms. We select the Earliest Deadline First (EDF) scheduling (Liu and Layland 1973) as a dynamic priority scheduler. If the tasks are scheduled by a fixed-priority scheduler, we make the following assumptions. Each task...
Lock-free (or non-blocking) algorithms [12,13] guarantee eventual progress of at least one operation under any possible concurrent scheduling. Thus, lock-free This research was supported by THE ISRAEL SCIENCE FOUNDATION (grant No. 274/14). c Springer International Publishing Switzerland 2016 P.-...
The operating system (OS) regulates access to a computer's central processing unit (“processor”) by different programs running on the computer. Most OSs employ priority-based scheduling algorithms for this purpose. Priorities are typically assigned to programs according to the importance and/or urg...
