Modern C++ Threads

[fabianegli]

Comet uses a custom Thread Pool implemented with older standards which did not have some of the amenities afforded in C++17 and higher which make Threads Pools safer and more efficient. To prevent much of the work to adapt the current code to the new standards, one could use an existing Thread Pool library instead. There is one which is specifically tailored to scientific computing, easy to use which covers the needs of Comet, as far as I can tell. This would be the BS::thread_pool: a fast, lightweight, modern, and easy-to-use C++17 / C++20 / C++23 thread pool library.

That library looks nice especially with everything encapsulated in a single header file. This is one of those instances where I'm likely not going to personally look into modifying the thread pool code unless something were broken. It's not that I'm opposed to it but rather there's always going to be other higher priority tasks to tackle. Maybe there will be some time in 2026 when I'm completely out of things to work on that I'll look into this. If you're up to incorporating this thread pool library, I'd welcome that contribution!
