lte scheduling

The operating system is required to implement multiple processes and process scheduling. It is said that process scheduling is one of the most important parts of the operating system. I think this statement is too absolute a bit, just like many people often say, "a certain function than a certain function of high efficiency xx times", divorced from the actual environment, these conclusions are relatively o

Reload In view of the recent issues related to CPU usage that involve the scheduling algorithm of Linux kernel, it is necessary to understand. Therefore, I wrote this article. Common Linux tasks include real-time tasks and non-real-time tasks. The scheduling algorithm of real-time tasks is familiar to priority preemption or priority pree

today to talk about the operating system of several common process scheduling algorithm. So the first step is to understand what a process scheduling algorithm is? In simple terms, the resource allocation algorithm is based on the resource allocation strategy of the system. Give an example to illustrate. Assuming that a task is selected after execution completes to minimize a factor, this factor may be the

CPU scheduling, multi-channelProgramThe basis of the operating system. The computer's throughput refers to the number of processes processed by the computer per unit of time. CPU scheduling improves the computer throughput by switching the CPU between processes. We know that the execution of processes includes CPU execution and I/O wait cycles. The process must be continuously switched under these two
