Shinakawa + Original works reproduced please specify the source + "Linux kernel analysis" MOOC course http://mooc.study.163.com/course/USTC-1000029000Linux supports both common ticks and real-time processes, which are priority-based. Scheduling in Linux is a mixture of various scheduling strategies and scheduling algorithms, because different types of processes have different scheduling requirements, so the timing of scheduling is also different. These algorithms allow the system to run more eff

Scheduling Timing BackgroundDifferent types of processes have different scheduling requirementsThe first kind of classificationI/o-bond: Frequent I/O, often spending a lot of time waiting for I/O operations to completeCpu-bound: computationally intensive; requires a lot of CPU time to perform operationsThe second kind ofBatch process: You do not have to interact with the user, usually run in the background, and do not n

The Linux scheduler divides processes into three categories:1. Interactive process2. Batch Process3. Real-time processLinux uses different scheduling strategies based on the different classifications of the process . For real-time processes, a FIFO or Round Robin scheduling strategy is used. For normal processes, it is necessary to differentiate between interactive and batch-processing. Traditional Linux schedulers increase the priority of interactive
