### CUDA Architectures

Different NVIDIA GPUs have different CUDA architecture: [CUDA GPU Compute Capability](https://developer.nvidia.com/cuda-gpus)

To build for multiple GPU architectures (matching the GitHub CI releases), use `-DCMAKE_CUDA_ARCHITECTURES=90;89;86;80;75`:

```shell
mkdir build && cd build
cmake .. -DSD_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=90;89;86;80;75
cmake --build . --config Release
```

## Build with HipBLAS

This provides GPU acceleration using AMD GPU. Make sure to have the ROCm toolkit installed.
