Try OpenCL 2.0 on HD5500 iGPUs

[Biao_W_]

Hi Robert, 

From the experience of using recent Intel OpenCL SDK, it shows that the OpenCL 2.0 is only support for CPU.

The OpenCL version for GPU is still 1.2.

However, by checking Khronos OpenCL products, 

https://www.khronos.org/conformance/adopters/conformant-products/

it seems OpenCL 2.0 now also works on the HD5500 and up iGPUs.

Just want to know whether the latest OpenCL SDK ( or OpenCL Code builder ) support OpenCL 2.0 on HD5500 and up iGPUs ?

BTW, there used to be a nice table that lists the supported platforms and OS systems of OpenCL SDK. 

but it disappears since OpenCL SDK  turns into Code builder and integrated into INTL.

where it is now?

Hi Biao,

OpenCL 2.0 should work on HD 5300 (but only w/ coarse grain buffer SVM) and on HD5500+ (with fine grain buffer SVM).

The experimental OpenCL 2.0 CPU device should work on 4th Generation Intel(R) Core(TM) Processors with HD4200 - HD5200 graphics (Haswell) and on 5th Generation Intel(R) Core(TM) Processors (Broadwell). You need to provide "-cl-std=CL2.0" flag to clBuildProgram to build your program for OpenCL 2.0 device, since by default your program will be build for OpenCL 1.2.

I'll ask about the disappeared table.

Does new Intel HD 515 Skylake GPU in Core M products support ​fine grain buffer SVM under OpenCL 2.0 or like HD5300 supports coarse grain only?

[Robert_I_Intel]

Intel(R) 6th Generation processors with HD Graphics 515 should fully support fine grain buffer SVM.
