CppCon 2019: Eric Niebler, Daisy Hollman “A Unifying Abstraction for Async in C++”

http://CppCon.org — Discussion & Comments:   / cpp   — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2019 — Async in C++ is in a sad state. The standard tools -- promises, futures, threads, locks, and std::async -- are either inefficient, broken, or both. Even worse, there is no standard way to say where work should happen. Parallel algorithms, heterogeneous computing, networking & IO, reactive streams, and more: all critically important foundational technologies that await a standard abstraction for asynchronous computation. In this talk, Eric Niebler and David Hollman dig into the Standard Committee's search for the basis operations that underpin all asynchronous computation: the long-sought Executor concept. The latest iteration of Executors is based on the Sender/Receiver programming model, which provides a generalization of many existing paradigms in asynchronous programming, including future/promise, message passing, continuation passing, channels, and the observer pattern from reactive programming. It also has surprising and deep connections to coroutines, which further demonstrates the model’s potential to be a truly unifying abstraction for asynchronous programming in C++20 and beyond. Eric and David will present the short-term and long-term directions for Executors in ISO Standard C++, illustrating the design by walking through several implementation examples. They will talk about the direct connection between coroutines and the Sender/Receiver model and discuss what it means for the future of asynchronous APIs in C++. Finally, they will cover how the restrictions imposed by the Executors model should affect the way you write code today so your code is ready for the next big revolution in parallel and concurrent C++ programming. — Eric Niebler Facebook Sr. Dev. Seattle I've been doing C++ professionally for the past 20 years, first for Microsoft, then as an independent consultant. Right now, I'm working on bringing the power of "concepts" and "ranges" to the Standard Library with the generous help of the Standard C++ Foundation. Ask me about the future of the Standard Library, or about range-v3, my reference implementation for C++11. Daisy Hollman Sandia National Labs Senior Member of Technical Staff Livermore, California Dr. Daisy Hollman has been involved in the ISO-C++ standard committee since 2016. He has been a part of a number of different papers in that time, including `mdspan`, `atomic_ref`, and—most prominently—executors and futures. Since finishing his Ph.D. in computational quantum chemistry at the University of Georgia in 2013, he has mostly worked on programming models for computational science, data science, and related fields. He joined Sandia National Labs in 2014 and has worked on several different programming models projects since then. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com *-----* Register Now For CppCon 2022: https://cppcon.org/registration/ *-----*
