### Asynchronous programming in .NET by Gerardo Lijs Twitter @GerardoLijs April 2019 ## Content What is Asynchronous Programming CPU-bound vs IO-bound Obsolete patterns Tasks and async/await Practical Count(n => Enumerable.Range(2, (int)Math.Sqrt(n) - 1).All(i => n % i > 0)); } ## Asynchronous method Task GetPrimesCountAsync(int start, int count) { return Task.Run(() => of the time you will need asynchronous to deal with IO-bound operations and the times you will use CPU-bound operations you will probably use a library that provides asynchronous methods for you to interact

## +23 ## Taro: Task graph-based Asynchronous Programming Using C++ Coroutine DIAN-LUN LIN 20 23 October 01 - 06 ## Agenda • Understand the motivation behind Taro • Learn to use the Taro C++ programming Conclusion ## Synchronous/Asynchronous Mechanisms Synchronous Boil the water  Multitasking! Asynchronous Wait ![Image]( create an async task to schedule ## • Boost Fiber 1. Wrap Boost Fiber within our task graph framework to allow for the creation and management of task graphs ## - Large-scale circuit simulation workload
