Implementing Peterson’s Algorithm for Mutual Exclusion in C Language After studying the section on process mutual exclusion, I thought I would try to implement it using user-level multithreading in C, which led to this article. Complete Code Peterson’s algorithm combines the single flag method and the double flag method to achieve true mutual exclusion for … Read more
01 Use Structures to Store Common Variables in AdvanceWhen writing preprocessing and postprocessing functions, certain variables, such as the shape of the model input tensor and count, are often used multiple times. If these values are recalculated in each processing function, it will increase the computational load during deployment. In such cases, consider using a … Read more
In multithreaded programming, there are two issues to pay attention to: one is data races, and the other is memory execution order. What is a data race? First, let’s look at what a data race is and what problems it can cause. #include <iostream> #include <thread> int counter = 0; void increment() { for (int … Read more
ver0.3 Introduction Those who have persisted in reading this article are already remarkable, as they now understand the weak memory ordering architecture of ARM. You not only understand the types of memory, the memory sharing mechanisms, and the memory consistency mechanisms, but also the CPU architecture and the microarchitecture of processors, all of which lay … Read more

Concept of Thread Synchronization Condition Variable: When a thread accesses a variable exclusively, it may find that it cannot proceed until other threads change the state. For example, … Read more
1. Concurrency Models: Python’s “Three Pillars” Python provides three core concurrency models, each with its own strengths: • Multithreading: Suitable for I/O-bound tasks • Multiprocessing: Suitable for CPU-bound tasks • Asynchronous IO: The king of high concurrency Performance Comparison: Model Switching Overhead Memory Usage Applicable Scenarios Multithreading Low Low File I/O/Network Requests Multiprocessing High High … Read more
Click the blue text to follow us Hello everyone, I am Cai Ge. Today we will talk about concurrency in Python, especially the use of <span>ThreadPoolExecutor</span>. Concurrency is a very important topic, especially when handling multiple tasks such as network requests and file operations. Through concurrency, we can improve the execution efficiency of programs and … Read more
Multithreaded Programming in C: Using the pthread Library In modern software development, multithreaded programming is an important method for handling concurrent tasks. Although C is a low-level language, it provides powerful tools for implementing multithreading, the most commonly used being the <span>pthread</span> (POSIX Threads) library. This article will detail how to use the <span>pthread</span> library … Read more
Practical C++ Multithreading Programming Introduction C++ is a powerful programming language that excels not only in system-level programming and game development but also supports multithreading. Multithreading can improve the responsiveness and processing capability of programs, allowing them to execute multiple tasks simultaneously. In this tutorial, we will delve into multithreading programming in C++, including how … Read more
