# Day 4

The focus of **Day 4** is **cuBLAS Vector Addition**

---

## Code Descriptions

### `cublas_vec_add.cu` (Vector Addition using cuBLAS)
- Implements **vector addition** using the cuBLAS SAXPY operation.
- Avoids explicit `cudaMemcpy` by utilizing `cublasSetVector` and `cublasGetVector`.
- Uses the **cuBLAS API** for optimized **GPU-accelerated BLAS operations**.
- Performs **C = A + B** efficiently with `cublasSaxpy`.

## Profiling and Running

To compile and run the CUDA program, use:

```sh
nvcc -o cublas_vec_add cublas_vec_add.cu -lcublas
./cublas_vec_add
