Chapter 23rd UNIX File SystemNamed pipe Mkfifo:mkfifo [-M mode] pipe. Named pipes must be created explicitly and will not disappear (the RM command can be removed).The proc file is a pseudo-file used to access kernel information. For example, if a process ID is 1952, the process-related information can be found in a file in the/proc/1952 directory.The VFS (virtual file system) implements the details of file processing.24th Directory Operations~ Represents the home directory; CD-you can switch to

Priority algorithm (SJF) Pick the minimum required CPU time in the queue to perform the job first. However, the implementation of the SJF algorithm needs to know the job run time beforehand, otherwise there is no basis for scheduling. 3. Shortest remaining time Priority algorithm (SRTF) A stripped-down scheduling algo

Little Chenbo main 2017-11-30 21:11:56 preface to the Broken language In the stand-alone application period, the task scheduling is generally based on spring schedule and integrated quartz to achieve, when the system developed into distributed services, the application of multiple instances, the task will appear many times the problem, many times our task does not need to run many times. There are many solutions, the simplest and most brutal of which

(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

In some cases, we usually need the software to have a function to automatically execute certain tasks, but we do not want to start the software directly or start the software manually every time, now we can consider windows Services. First, create a windows Service Project (for more information, see:C # basic tutorial on creating a Windows Service) 　　　　 In the created Project, click "Click here to switch to Code view" to switch to the Code view. We ma
