Coros – A Modern C++ Library for Task Parallelism
Hello Hacker News. I’m Martin, a graduate student from Prague, and I’ve been working on Coros, a C++ library for task-based parallelism. After spending some time with OpenMP and oneTBB, I wanted to try building a library using modern features from the C++ standard library. I’ve used coroutines for task encapsulation and C++23 expected for exception handling, while trying to maintain good performance. Additionally, I’ve implemented monadic-like behavior to allow easy chaining of tasks, similar to the monadic operations in std::expected. You can check out the project here:…
In plain words
Coros is a C++ library for task-based parallelism built using modern standard library features including coroutines and C++23 expected for exception handling. It provides monadic-like behavior for chaining tasks together. The library is designed for developers working with parallel computing in C++ who want to leverage contemporary language features instead of traditional frameworks like OpenMP or oneTBB. The project is currently experimental and under development.
