There are other ways of achieving parallel computing in Rust and in many other languages. In this chapter, we will talk about multithreading, where each thread has access to shared memory and creates its own stacks so that it can work independently. Ideally, you should have about the same number of threads working at the same time as the number of virtual CPUs in your PC/server.
This is usually twice the number of CPU cores, thanks to hyperthreading, where one core can run two threads at the same time by using its own hardware scheduler to decide which parts of each thread run at a given point in time.
The main issue with threads is that if you don't put a limit and run too many of them, maybe because some ...
