OpenCL on Intel processors

[Benson Muite]

Hi,

Beignet has been deprecated, might it be possible to put Intel(R) 
Graphics Compute Runtime for OpenCL(TM) in the Fedora repositories? 
There is a COPR repository at:

https://copr.fedorainfracloud.org/coprs/jdanecki/intel-opencl/

Is there a means by which generation of CPU and GPU being used can be 
detected to give a warning or recommendation as to the compatibility of 
the OpenCL library?

It should be possible, it looks like it's MIT licensed. Have you tried
contacting the maintainer of that COPR?

Unfortunately the one above is for Broadwell and newer, which means
it doesn't work with any of my machines.

Don't you love planned obsolescence? A whopping 3 CPU/IGP generations from 
https://wiki.freedesktop.org/www/Software/Beignet/#supportedtargets got 
dropped by the rewrite. :-(

Will Beignet be kept in Fedora or will everyone with those 3 CPU/IGP 
generations be stuck with running POCL on the CPU (essentially defeating the 
purpose of OpenCL) instead?

I've dropped beignet a while ago since I was getting bugs, but upstream is
dead. Also many times, POCL performed better than beignet.

And after all, if you want to do something complicated with OpenCL, you
already have high-end AMD or latest Intel card..

However, anyone is free to unretire it.

Ok. Arm and AMD also support OpenCL

https://developer.arm.com/solutions/graphics/apis/opencl

https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime

https://rocm.github.io/install.html

AMD part for OpenCL only seems to be MIT licensed.

Yes, he is responsive:
