Title
A Unifying Abstraction for Async in C++

Abstract
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 digs 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 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, he 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 has worked with Andrei and I in the early days of D. He's one of the top 
C++ people in the world, and it is well worth coming to hear him speak.
Besides, 
most importantly, we go out for a beer afterwards!

Come join us, it'll be fun!

They usually are, but sometimes something goes wrong with the camera.

Looking forward to: DLang using await as a standard abstraction for asynchronous computation.
