Multithreading is the Answer. What Was the Question? - Part I

Explore the intricacies of multithreading in C++ programming through this comprehensive CppNow conference talk. Delve into various problems solvable with multithreaded concepts and techniques, while examining challenges in designing and implementing multithreaded applications. Learn strategies to mitigate these challenges and recognize when to avoid multithreaded code. Cover topics ranging from high-level architecture to low-level C++ classes that enhance readability and maintainability of multithreaded code. Gain insights into C++11 multithreading, C++17 concurrency TS, and new abstractions built on these features. Discover multithreading myths, understand concepts like race conditions, fibers, and green threads, and explore real-life examples to grasp the practical implications of multithreading. Examine optimization techniques, deadlock prevention, resource management, and the use of futures and promises. Dive into advanced topics such as atomic operations, resource locks, undefined behavior, and memory barriers to deepen your understanding of efficient multithreaded programming in C++.
