Mastering std::execution (Senders/Receivers)

A Hands-On Workshop

Available to book as a 1 day online workshop on the following dates

Friday 15th May 09:00 - 17:00 UTC

Suitable for:

Beginner

Asynchronous

Today, C++ software is increasingly asynchronous and parallel, a trend that is likely only to continue going forward. While the C++ Standard Library has a rich set of concurrency primitives and lower-level building blocks, we lack a standard framework for asynchrony and parallelism that C++ programmers desperately need. Asynchrony and parallelism appear everywhere, from processor hardware interfaces to networking, to file I/O, to GUIs, to accelerators. Every C++ domain and every platform needs to deal with asynchrony and parallelism, from scientific computing to video games to financial services, from the smallest mobile devices to your laptop to GPUs in the world's fastest supercomputer. This training shows that concurrency is not only about the C++ Standard Library threading and synchronization low-level tools. During the workshop, you will learn how to write efficient, asynchronous, and highly concurrent code without the need for any manual synchronization between threads, leading to simpler code and faster runtimes. During the hands-on exercises, you will create parallel processing pipelines with a new std::execution framework, also called Senders/Receivers, which will arrive as a part of C++26. The reference implementation of this framework is publicly available on GitHub so that it can be used in production immediately without the need to wait for the next C++ release.

What You Will Learn?

Understand what structured concurrency is and how it helps write thread-safe code without the need for additional synchronization.
How to build a complex asynchronous pipeline with schedulers, senders, and receivers in a few lines of code.
Practical usage of all the asynchronous algorithms provided by the std::execution framework.

Attend The Workshop Taster - 11th - 13th March

If you are unsure or want a better understanding of how the workshop works in practice, then you can attend a taster session for this workshop by purchasing a ticket for the main conference which will run over 3 days from 11th-13th March and which will feature over 25 C++ talks.

You can upgrade your main conference ticket to a workshop ticket at no extra cost compared to purchasing the workshop ticket directly!

The workshop taster is designed to provide you with a preview/overview of this workshop where you will also have an opportunity to ask questions. In addition, the workshop preview will be made available on-demand for you to watch at your own convenience.
