Top 8 C++ Threadpool Projects

Taskflow

24 9,520 7.9 C++

A General-purpose Parallel and Heterogeneous Task Programming System

Project mention: Improvements of Clojure in his time | /r/Clojure | 2023-06-16

For parallel programming nowadays, personally I reach for C++ Taskflow when I really care about performance, or a mix of core.async and running multiple load balanced instances when I’m doing more traditional web backend stuff in Clojure.

concurrencpp

16 2,047 1.2 C++

Modern concurrency for C++. Tasks, executors, timers and C++20 coroutines to rule them all

Project mention: Is anyone using coroutines seriously? | /r/cpp | 2023-12-05

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

Project mention: How do I improve my SB3 PPO on an EnvPool environment | /r/reinforcementlearning | 2023-09-21

I am looking to improve the overall performance as well as optimize the wall clock time. I slightly modified the code to develop a SB3 wrapper for envpool from here.
