CppCon 2016

Asynchronous I/O is an essential technology for increasing concurrency without introducing more threads, which carry both overhead and risks. Unfortunately, leveraging async I/O can be disruptive to careful code architecture.

This talk focuses not on the mechanics of async I/O, but rather on a library that manages async I/O with code that looks and behaves like traditional sequential code. Boost.Fiber introduces "userland threads," permitting the application coder the benefits of both async I/O and clean layers of abstraction.

This talk presents an overview of the library, discusses integration with event-driven frameworks and illustrates several useful patterns.
