Coroutine made DPDK dev easy
So, we try to use Photon coroutine lib to simplify the development of DPDK applications with the new concurrency model, and provide more functionalities, such as lock, timer and file I/O. First of all, we need to choose a userspace network protocol stack. After investigation, we have chosen Tencent's open source F-Stack project, which has ported the entire FreeBSD 11.0 network protocol stack on top of DPDK. It also has made some code cuts, providing a set of POSIX APIs, such as socket, epoll, kqueue, etc. Of course, its epoll is also simulated by kqueue, since it is essentially FreeBSD.

Is anyone using coroutines seriously?
I am using concurrencpp for my project. What I like about it is that it's basically a thread pool factory with coroutines. It allows for better structuring / organizing of multithreaded work. So for me the main advantage of coroutines is that the code looks easier to follow

Do you think the current asynchronous models (executors, senders) are too complicated and really we just need channels and coroutines running on a thread pool?
I agree. I use concurrencpp for the exact use case you described - coroutines running on simple-to-understand-executors which return some asynchronous pipe for communication.
- concurrencpp version 0.1.6 has been released!

What happens if you co_await a std::future, and why is it a bad idea? - The Old New Thing
If you look at concurrencpp, you can control exactly where and how coroutines are resumed, using executors.

Header-only C++14 quality thread pool
Hi, I am looking for a header-only C++14 (or lower) quality thread pool. Ideally, it would be similar to BS::thread_pool but in C++14. Most of them I find on GitHub are bloated (e.g. concurrencpp) or have many open Issues. Ideal usage would be similar to:

Good repos for beginners to browse that follow best modern C++ practices (including testing, static analysis etc...)
I use concurrencpp for my asynchronous code and the repo is written in modern cpp, with tests, sanitizers and what not.
