Automatic parallelization

Okay kiddo, let me explain automatic parallelization to you in a way that you can understand. Have you ever done a jigsaw puzzle? Well, imagine that instead of doing it all by yourself, you have a few friends who can help you. But you want to make sure that each person is working on a different part of the puzzle so that you can finish it faster.

That's kind of like what automatic parallelization does. When a computer program runs, it can be broken down into many different parts, kind of like puzzle pieces. Automatic parallelization helps the computer figure out which parts can be worked on at the same time by different parts of the computer, just like each of your friends working on a different part of the jigsaw puzzle.

But how does the computer know which parts can be worked on at the same time? Well, it looks for certain patterns or instructions in the program that tell it which parts can be done independently of each other. Just like you might notice a pattern in the puzzle pieces that make it easier to put them together.

Once the computer figures out which parts can be done at the same time, it assigns each part to a different part of the computer to work on. This is called "parallelizing" the program, which means that multiple parts of the program are running at the same time, or "in parallel". And just like how you and your friends can finish the puzzle faster by working on different parts at the same time, the computer can finish running the program faster by parallelizing it.

So that's what automatic parallelization is, kiddo. It helps computers run programs faster by breaking them down into different parts and working on them at the same time, just like how you and your friends can finish a puzzle faster by each working on a different part.
