for future reference, many older than coffee lake CPUs, support OpenCL 1.2 as well, allowing you to run GPU projects on older Intel Core, and Intel Intel Atom processors (like the N3060 and earlier).
They're not particularly fast, but now you can!
Generally speaking, you'd have to install the intel-opencl support files:
sudo add-apt-repository ppa:intel-opencl/intel-opencl
sudo apt update
sudo apt install intel-opencl-icd
However, if you have an old Intel CPU, the following 'beignet' drivers should do the trick, and can be natively installed from the included Ubuntu Repositories:
sudo apt install beignet-opencl-icd
it supports following IGPs:
3rd Generation Intel Atom Processors "BayTrail".
4th Generation Intel Core Processors "Haswell", need kernel patch if your linux kernel older than 4.2, see the "Known Issues" section.
5th Generation Intel Core Processors "Broadwell".
5th Generation Intel Atom Processors "Braswell".
6th Generation Intel Core Processors "Skylake" and "Kabylake".
5th Generation Intel Atom Processors "Broxten" or "Apollolake".
