Download opencl_runtime_16.1.2_x64_rh_18.104.22.168.tgz from http://registrationcenter-download.intel.com/akdlm/irc_nas/12556/opencl_runtime_16.1.2_x64_rh_22.214.171.124.tgz. Currently, Intel opencl has github project with 18.X versions. All 18.X versions don’t work for me, and 16.1.2 version is latest workable version I can find.
Extract downloaded file (tar -xvf opencl_runtime_16.1.2_x64_rh_126.96.36.199.tgz) then run install.sh with root permission. If you have missing libraries in this step (screenshot bellow), you can exit installation and install libraries. If there is only lsb-core>=4.0 is missing, you can move to next step (it worked for me).
