1, why process scheduling is requiredFirst, we need to make it clear that process scheduling is the process of scheduling a task_running state (see "Analysis of Linux process status"). If the process is not executable (sleeping or otherwise), it has little to do with process scheduling.So, if your system loads very low, expect the stars to look forward to the moo

I) Summary of the I/O Scheduler 1) when a data block is written to or read from the device, the request is placed in a queue waiting for completion.2) each block device has its own queue.3) the I/O scheduler is responsible for maintaining the order of these queues to make more effective use of media. the I/O scheduler converts unordered I/O operations into ordered I/O operations.4) The kernel must first determine the total number of requests in the queue before

Linux schedules many processes. This involves the concept of Linux Process Scheduling timing, which is determined by the Schedule function in the Linux kernel, if you want to switch, which process to switch to, and so on. Linux Process Scheduling time mainly includes:: 1. process state transition time: Process Termination and process sleep; 2. When the time slice of the current process is used up, current->

The process scheduler can be seen as a kernel subsystem that allocates a limited amount of processor time resources between running too processes. The scheduler is the basis for multitasking operating systems. Through the reasonable scheduling of the scheduler, the system resources can play a maximum role, the multi-process will have the effect of concurrent execution.The principle of maximizing processor time is that as long as there are processes th

(1) For the CPU, there are many processes, which one needs to be done first, or which one needs to be done later? This is scheduling; (2) job status: the job generally needs to go through four stages: "Submit", "backup", "run", and "complete". (3) submission status: after a job is submitted to the data center, the job is in the submitted status after being input through the spooling system process or when the user enters the job to the computer throug

1. First come first service (FCFS) scheduling algorithm1. It can be used for job scheduling, or for process scheduling.2. It is a priority to consider the longest waiting time in the system for the job or process.3. Do not take into account the duration of the job or process execution time.principle: Each time you select a process from the process readiness queue
