The installation page for the OpenCL CPU runtime instructs the following:

wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | gpg --dearmor | sudo tee /usr/share/keyrings/oneapi-archive-keyring.gpg > /dev/null
echo "deb [signed-by=/usr/share/keyrings/oneapi-archive-keyring.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list
sudo apt update
sudo apt install -y intel-oneapi-runtime-opencl

On a fresh Ubuntu Server 23.04 installation, this broken however, with the error that libsvml.so is missing. This error shows up when starting any OpenCL application. Further, it breaks any other existing OpenCL runtime installation, like for Nvidia GPUs.

Additional installation of

sudo apt install -y intel-oneapi-runtime-libs

is required to fix the issue.

Please add the missing library/dependency to intel-oneapi-runtime-opencl, or at least update documentation that intel-oneapi-runtime-libs is required too.

A similar issue affects the standalone OpenCL CPU runtime installer on Windows, it is currently broken and the older working version is not available for download anymore. This should be fixed in the released executable, rather than directing users to mess with the registry in the Known Issues.
