Top 7 C++ concurrent-programming 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 2,028 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

WorkOS

The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
sobjectizer

13 456 9.1 C++

An implementation of Actor, Publish-Subscribe, and CSP models in one rather small C++ framework. With performance, quality, and stability proved by years in the production.

Project mention: SObjectizer Tales - 27. Design ideas | dev.to | 2024-04-11

An additional rationale for structuring cooperations in hierarchies is to facilitate the sharing and propagation of dispatchers. A recent update of SObjectizer includes new functionalities that allow access to both agent and cooperation dispatchers. This enhancement was prompted by feedback provided by a user and myself.

hspp

9 153 0.0 C++

hspp: An experimental library to bring Haskell Style Programming to C++.
Lazy

5 109 2.6 C++

Light-weight header-only library for parallel function calls and continuations in C++ based on Eric Niebler's talk at CppCon 2019.
TDP

1 87 0.0 C++

The Darkest Pipeline - Multithreaded pipelines for modern C++
so5extra

2 22 5.1 C++

so5extra is a collection of various SObjectizer's extensions. so5extra is built on top of SObjectizer and intended to simplify development of SObjectizer-based applications.

Project mention: SObjectizer Tales - 26. Dispatcher selection | dev.to | 2024-04-04

In this case, it’s possible that we need to craft and use a custom dispatcher for the purpose. This might be not an easy task in general but we know where to start as we learnt in this previous post. For example, in calico we have discussed and crafted a do_gui_message_loop() function to guarantee the OpenCV drawing happens on the calling thread – and we call this function from the main thread. An alternative solution consists in developing a customized dispatcher. Just to share another example, SObjectizer’s companion project so5extra, provides some battle-tested dispatchers tailored for boost ASIO.
