Installation procedure on Ubuntu 18.04

1. Create temporary directory

Example:

mkdir neo

2. Download all *.deb packages

Example:

cd neo
wget https://github.com/intel/compute-runtime/releases/download/20.34.17727/intel-gmmlib_20.2.4_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.34.17727/intel-igc-core_1.0.4756_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.34.17727/intel-igc-opencl_1.0.4756_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.34.17727/intel-opencl_20.34.17727_amd64.deb

wget https://github.com/intel/compute-runtime/releases/download/20.34.17727/intel-level-zero-gpu_1.0.17727_amd64.deb

3. Verify sha256 sums for packages

Example:

wget https://github.com/intel/compute-runtime/releases/download/20.34.17727/ww34.sum
sha256sum -c ww34.sum

4. Install all packages as root

Example:

sudo dpkg -i *.deb
