Looking for Books on Concurrency and Multithreading Concepts

Check out *The Art of Multiprocessor Programming* by Herlihy & Shavit. The first edition is accessible for free through the ACM Digital Library, while the second edition includes new chapters and exercises. It primarily covers the underlying principles and how to apply them, heavily using Java but applicable to other languages too!

While I don't have specific book recommendations, I suggest checking out some video resources. There's a channel called @CoreDumpped that covers a lot of great material on these topics.

To sum it up: processes in an OS run concurrently, with each getting its own time slice to execute. Threads, on the other hand, are like mini-processes—they share the same virtual address space but can run concurrently or even in parallel if you have enough CPU cores. When a thread finishes its task, it might need to be recreated, or you can have a set number of threads ready to handle requests, like in C#'s thread pools.

I got into concurrency during my OS class, and I used a bunch of resources there. I remember reading Stallings’ OS book and also 'OS in Three Easy Pieces.' While I haven’t read a specific concurrency book for a programming language, I’d love to see what others suggest as well!
