C++11 to C++23 in the C++ Memory Model - Alex Dathskovsky - C++Now 2024

Alex Dathskovsky explains the evolution of the C++ memory model and how to write correct parallel code using atomics.

cppnow.org --- C++11 to C++23 in the C++ Memory Model - Alex Dathskovsky - C++Now 2024 --- In the realm of C++ development, threading and memory management play a crucial role in crafting highly parallel and optimized programs. However, the absence of a memory model in C++98 posed challenges. Thankfully, with the advent of C++11, significant changes were introduced, including the introduction of a memory model, which brought forth a plethora of new and exciting tools for developers to leverage. This talk aims to delve into the realm of the C++ memory model, showcasing the arsenal of tools at our disposal. Attendees will gain insights into how CPUs and compilers optimize code and understand the criticality of adhering to the memory model correctly. Practical guidelines on utilizing these tools effectively will also be explored. Throughout the talk, we will illustrate practical examples and share best practices for utilizing the diverse set of tools now available to us. From atomic operations to memory barriers, we will explore the range of techniques that allow us to develop robust and thread-safe code. This talk will also illustrate the newer tools from newer C++ standards like JThread and so this talk will show how memory model is used and how it advanced since C++11 --- Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Pres… --- Alex Dathskovsky Alex has over 17 years of software development experience, working on systems, low-level generic tools and high-level applications.
