process scheduling Basic Properties1. Polymorphism from birth, run, until eliminated. 2. A number of different processes can include the same program 3. Three basic states can be converted between them 4. Concurrency concurrent

First, uptimeThe results of the uptime command include how long the server has been running, how many logged-in users, and the overall evaluation of server performance (load average). The load average values are recorded for the last 1 minutes, 5

Scheduling Algorithm and Resource Scheduling Algorithm In a multi-channel program environment, there are multiple processes in the main memory, and the number of processes is usually more than the number of processors. This requires the system to

1. Before the introduction of the process scheduling, the concept of the state of the process should be understood, the following is a few basic concepts of process State, the status of the process is divided into three kinds, namely:1). operating

C # thread, Processes and threads A process is a system-level concept used to describe the memory allocation required for a group of resources and programs. Each process has a unique PID. The thread is the basic unit of the process. The first thread

Using the top or PS command will output pri/pr,NI,%ni/%nice These three indicator values, what exactly is this thing? The approximate explanation is as follows:　　PRI : Process priority, which represents the priority that the process can be executed,

Linux scheduling Summary Scheduling: Two Tasks of the scheduling program of the operating system: 1: scheduling: Implement Scheduling Policies and decide the ordering of ready processes and threads competing with cpu. To put it bluntly, the process

In the system, the number of user processes is generally more than the number of processors, which will cause them to compete with each other processor. In addition, the system process also needs to use the processor. This requires the process
