Concurrency With Modern C++ [2021 class archive]

Concurrency with Modern C++ is a three-day online training course with programming examples taught by Rainer Grimm. It is offered online from 09:00 to 15:00 Aurora time (MDT), 11:00 to 17:00 EDT,  17:00 to 23:00 CET, Wednesday, October 20th through Friday, October 22nd, 2021 (before the conference).

Course Description

This class gives you a detailed insight into the multithreading facilities of C++11 and C++14, the parallel algorithms which we got with C++17, and the new way of concurrency, we will get with high probability in C++20.

Additionally, we will have a more in-depth look into the C++ memory model consisting of the atomics and the various memory orders in C++. This insight will provide you with a better understanding of the general concurrency features of C++.


Participants should have a basic knowledge of the C++ language and the fundamentals of multithreading.

In the class, I will give you a concise introduction to the topic. This introduction provides the starting point for the exercises; therefore, you should bring your laptop with you including a C++11 or C++14 compiler.

You will get in return the training material consisting of the presentation, the exercises, and the solutions to the exercises.
