# Intro

This project is a hands-on CUDA programming library designed to help learners master CUDA fundamentals and their integration with PyTorch. 
Unlike the official NVIDIA documentation, which often requires substantial time and effort to digest, 
we focus on real-world examples and concise explanations to make the learning process more intuitive and efficient. 
Several key modules include progressive versions, allowing readers to build understanding step-by-step while learning practical optimization techniques for kernels and functions. 
To keep compilation straightforward, each module is self-contained and organized in its own file.

eg.

```
cd matrix_multiply 
make
./matMul
```
