Hi,
I'm using Fedora 30 linux on Haswell (4th gen) and Ivybridge (3rd gen). Until Fedora 29, beignet comes with Fedora as a package, but beignet is produced on non-profit basis, so its development is stalled in favor of OpenCL Runtimes for Intel Processors although this does't support 4th gen processors or earlier ones.
I bought Haswell and Ivybridge only 2 years ago secondhand, and they are still working very fine. Personally I use beignet OpenCL only on Haswell, but lots of people must be using old processors and want to use Intel's OpenCL.
So I want OpenCL Runtimes for Intel Processors to support 4th gen processors and earlier....Its demand must be huge.
