HIP-nvcc is the compiler for HIP program compilation on NVIDIA platform.
* Add the ROCm package server to your system as per the OS-specific guide available [here](https://rocm.github.io/ROCmInstall.html#installing-from-amd-rocm-repositories).
* Install the "hip-runtime-nvidia" and "hip-devel" package. This will install CUDA SDK and the HIP porting layer.
* Install Nvidia Driver
```
apt-get install hip-runtime-nvidia hip-devel
sudo apt-get install ubuntu-drivers-common && sudo ubuntu-drivers autoinstall
sudo reboot
```
Or download the latest cuda-toolkit at https://developer.nvidia.com/cuda-downloads
The driver will be installed automatically.
* Add the ROCm package server to your system as per the OS-specific guide available [here](https://rocm.github.io/ROCmInstall.html#installing-from-amd-rocm-repositories).
* Install the "hip-runtime-nvidia" and "hip-dev" package. This will install CUDA SDK and the HIP porting layer.
```
apt-get install hip-runtime-nvidia hip-dev
```
* Default paths and environment variables:
* By default HIP looks for CUDA SDK in /usr/local/cuda (can be overriden by setting CUDA_PATH env variable).
* By default HIP is installed into <ROCM_PATH>/hip (can be overridden by setting HIP_PATH environment variable).
* Optionally, consider adding <ROCM_PATH>/bin to your path to make it easier to use the tools.
