operator fusion does at the compiler level: merges adjacent ops to reduce memory traffic

Did you know your computer can write faster code than you?

Imagine you're writing a novel and you want to finish faster. You decide to write shorter sentences to speed up the process.

By combining short sentences, you can write faster without changing the story. This is like merging adjacent operations to reduce memory traffic, making the computer run more efficiently.

Example

Instead of writing "The cat sat on the mat" as two separate sentences, you write "The cat sat on the mat." This saves time and space.

Remember this

It's like writing shorter sentences to finish your novel faster; merging adjacent operations reduces memory traffic for quicker computer performance.
