Phoronix: Beignet Is Working On OpenCL 2.0 Open-Source Linux Support

While writing this morning about Intel Cherryview support being added to Beignet, I also noticed Intel developers have been quietly fleshing out OpenCL 2.0 support for Linux...

Nevertheless, it's great that Intel is continuing to invest in open-source OpenCL support with multiple developers working on Beignet while the overall open-source/Linux OpenCL scene remains in relatively sad shape

And that is only because Intel has been intentionally fragmenting mesa. They've had plenty of time to move on to gallium, but they have chosen not to. It's not due to technical reasons, just corporate sabotage.

Of course it is a good thing that Intel is releasing code, even though it's fragmenting existing infrastructure.

Ofcourse, Fragmenting mesa code is not good idea, however CLover still is incomplete OpenCL 1.1 implementation and it would be rewritten.

Hey guys,

The impact of disabling batch buffer security for Intel Haswell
platform on Linux for OpenCL kernels that need local shared memory
access is massive.

On a native kernel with and without the patch, the performance boost
is massive, especially ijn the Lu decomposition benchmark.

Do the math for yourself here. Note that the latest result is labelled
"Asus GTX 860M" and its' at the bottom of the list.

The test labelled i7 4700HQ should be identical to the Asus GTX 860M,
it was simply mis-labelled in another previous test.

The patchwork is here:

The results of the benchmark is right here:

http://openbenchmarking.org/result/1505138-DE-1409234KH90

The performance was noted for both the Intel IGP + the discrete NVIDIA GPU as both OpenCL ICDs (Intel's Beignet + NVIDIA CUDA's OCL) are installed on the system. Currently running Arch Linux.
