1, Overview of producer consumer issues Description: two or more threads share the same buffer. One or more threads as a "producer" will constantly add data to the buffer, and the other or more threads as a "consumer" will take data from the buffer. Note the following: Producers and consumers must use buffers that ar ...

preface   this paper implements four disk scheduling algorithms FCFS/SSTF/SCAN/CSCAN in C language. It provides manual input of track number and random generation of track number. The output is the track number accessed at each step, the moving distance at each step and the average moving distance.    in addition to the consiste ...

Experiment 1 design and implementation of process scheduling algorithm dynamic priority plus time slice rotation method for process scheduling 1. Content: design a simple process scheduling algorithm to simulate the process scheduling process in OS; 2. Requirements: ① The number of processes shall not be less than 5; ② There are three process s ...

here , the format of the library's bookshelf, that is, the file system on the hard disk, has been built. Now we also need a library management and borrowing system, that is, the file management module. If a process wants to write data into the file system, it needs the cooperation of many layers of components: In the application layer, when ...

(operating system) design a processor scheduling program according to the priority number scheduling algorithm. (Tip: the code is for reference only. If there are any errors, please correct them. The comments are just written casually and record the thinking process. If you can't understand your own understanding, you csdn, don't ask others. I ...
