LeBlanc’s law: "Later equals never".
Summary In this post, I will introduce how to build a simple thread pool in C++. Conclusion The codes are from here. The thread pool only uses thread, mutex, and condition_variable. #include <thread> #include <mutex> #include <condition_variable> class ThreadPool; // our worker thread objects class Worker { public: Worker(ThreadPool &s) : pool(s) { } void…
Summary In this post, I will introduce the correct way to use mutex in C++, compared to Java. Conclusion Try not to use std::mutex directly.

A mutex is destroyed while still owned by any…
Summary In this post, I will introduce how to solve a parallel computation task using Intel Threading Building Blocks. Problem In the deep learning platform, given inputs contains several thousand images, we want to analyze the data path of a certain deep learning model. The analysis part of each image is identical, for example, we…
