Kernel-level thread and user-level thread, kernel-level thread user When I wrote this blog these two days, I reviewed the operating system materials and encountered a problem that I did not understand before, that is, about kernel-level threads and user-level threads. After reading some documents, I will share my personal profile. Threads have been implemented in

Summary of this chapter: 1: Termination status and non-termination status 2: differences between autoresetevent and manualresetevent 3: waithandle. waitone (), etc. 1: Termination status and non-termination status First, let's talk about the termination and non-termination states of the thread. Both autoresetevent and manualresetevent constructors have bool variables to indicate the termination and non-termination statuses of the

processor resources starts to run. Note that the program is not running after a certain processor time, and the processor time may need to be allocated again or multiple times. We can see from this that this execution method is obviously parallel execution of multiple programs, but at the macro level, we feel that multiple tasks are executed at the same time, therefore, the concept of multi-task was born. Each running program has its own memory space, its own stack and environment variable sett

Java multi-thread Development Series II: how to create multi-thread and multi-thread Series II I have already introduced the basic knowledge of multithreading, such as what is multithreading, what is a process, and why multithreading is used. After learning the basic knowledge about multithreading in software development, let's talk about how to use multithreadin

Thread granularity division, depth placement, and thread granularity in the thread pool Abstract: multi-threaded task processing is very helpful for improving performance. The thread pool provided in Java also facilitates the implementation of multi-threaded tasks. It is easy to use, and if you use it incorrectly, the

Java multi-thread (4) thread pool and java multi-thread pool A good software does not randomly create and destroy threads, because it takes a lot of CPU time and requires a lot of interaction with the memory. Therefore, JDK 5 proposes to use the thread pool so that programmers can focus more on the business logic and w

Linux thread control Thread separation, linux threadThread Concept A thread, sometimes called a Lightweight Process (LWP), is the smallest unit of the program execution flow.
