# Day 3

The focus of **Day 3** is **tiled matrix multiplication**

---

## Code Descriptions

### 1️`mat_mul_tiled.cu` (Improved matrix multiplication)
- Uses **shared memory** to store tiles of matrices. 
- Reduces global memory access latency. 
- Uses **tiling and thread-level parallelism** to optimize computation. 



## Profiling and Running

To compile and profile the CUDA codes, use:

```
nvcc -o compiled_code_name source_code.cu
nsys profile --stats=true compiled_code_name

```
