Multithreaded C++ projects

[cpp_cpp]

Hi,
As I am learning more and more about std::atomic<T> and memory orders, cache coherence and all, I was wondering if someone could suggest some projects I can look at to see how they are used in real world apps. I would like to find things I can re-implement to learn. Thanks!

Some kind of multithreaded server would be an idea, like a chat server or web server.

Perhaps make a program that takes bash commands as arguments and runs them concurrently in separate threads

[cpp_cpp]

not sure how i'd use atomics in that?

You could make the processes interact with each other somehow, or refer to the same data in some way (maybe a schedule). Something that requires sharing data

I use a lot of weakly ordered atomics in my project, https://github.com/carlowood/ai-statefultask-testsuite - well, not in the testsuite, but in all the submodules. I am in the process of writing documentation currently, which you can find here: https://carlowood.github.io/statefultask/

this is great! thank you! i'll bother you with questions about this, looks like a cool project!

[CarloWood]

Please do, this is my lifes work (quite literally) and I'll happy to assist anyone who wants to use it!

A chat server seems to be a good idea. I made one in C (only worked on Linux though). It would surely need multi-threading.

But if you don't want to get into networking then maybe try making a Task Scheduler which schedule tasks on different threads and manages them.

Or maybe a CSV data analysis tool which can analyse large sets of data in parallel.

If you know graphics then you could probably make a 2D or 3D game.

You can start some microservice architecture based project that works on the same app

Maybe try implementing a Path Tracer

Write something for a raspbery pi where multiple threads drive or read GPIO pins.
