HIP can be installed on AMD platforms using ROCm with HIP-Clang.
Refer to the Prerequisites section in the ROCm install guides:
HIP is automatically installed during the ROCm installation. If you haven't yet installed ROCm, you can find installation instructions here:
By default, HIP is installed into /opt/rocm.
Note
There is no autodetection for the HIP installation. If you choose to
install it somewhere other than the default location, you must set the
HIP_PATH environment variable as explained in
Build HIP from source.
Run hipconfig in your installation path.
/opt/rocm/bin/hipconfig --full
