Im very pleased to hear your ideas to distribute BLAS operation across Intel platform. I see great value to use the same API to utilize all performance features available on the compute system.
OpenCL also provides you the opportunity to use the same context to share memory objects between devices, synch on events between queues, compile once, etc.
This may also increase your ability to get the best of the platform, depends on your usage.
Did you find specific portion of the code that are more suitable the CPU or to the GPU?
As I mentioned in this forum few times in the past, I cannot comment at this point on our plans. But such feedback help us to understand your needs.
So please keep contribute, and we will publish as soon as a new version of OpenCL support will be available on Intel platforms.

Intels policy is to not comment or speculate on rumors or to discuss unannounced plans or products in this forum.
Intel does support OpenCL and continue evaluating when and where such support will intercept our hardware products.
Let's also not forget OpenCL. We initially asked Intel about OpenCL support at theClarkdalelaunch. The company said then it was aiming for mid-2010. As there's still no OpenCL support we asked again recently and were told:
'[Intel] will be releasing OpenCL graphics drivers to developers during the course of 2011. [Intel] continue to evaluate when and where OpenCL will intercept various products.'
Nothing new here. We are evaluating our new technologies such as OpenCL with our NDA customers as we always do. We will continue doing so during the course of 2011.
As an active Khronos Group member, Intel is working closely with others in the industry, including the developers community, to define the OpenCL standard.
Where is openCL 1.2 CPU support on Intel HD 3000 2nd gen processor????
I only found openCL 1.1 support. Is intel planning to provide driver support on intel hd 3000 on customer demand??????
Also openGL 3.3 is still not provided by intel on windows intel hd 3000 drivers. Currently the latest intel hd 3000 driver only supports openGL 3.1 on windows.
OpenCL 1.2 (CPU) support and OpenGL 3.3 is found on Linux and Apple Max OS X regarding intel hd 3000 driver. However windows driver is a total let down/disapointment. Are you planning to offer as an update since you have delayed any development regarding this API features???
I have an i7-2640m mobile processor with intel hd 3000 IGP I need the following driver support.
1. OpenCL 1.2 (as an update from openCL 1.1, for the CPU part)
2. OpenGL 3.3 (as an update from OpenGL 3.1)
3. WiDi driver for windows 10 for second gen CPU with intel hd 3000 IGP (e.g. i7-2640m)
I am repeating myself since I had no reply.
As far as I know there are no plans to support OpenCL 1.2 for the GPU for the 2nd generation Intel(R) Core Processors (Sandy Bridge) due to resource constraints. Our driver team is hard at work on the drivers for the 7th generation chips, so OpenCL 1.2 is only supported for 3rd generation Intel(R) Core Processors (Ivy Bridge). I am very sorry about the inconvenience that this issue causes.
As far as your other questions, for the OpenGL support please consider contacting OpenGL support forum https://software.intel.com/en-us/forums/developing-games-and-graphics-on-intel. There should be a separate forum for Wi-Di https://communities.intel.com/community/tech/intel_widi
Hi Robert, Thank you for your reply and the links.
Can you offer a OpenCL 1.2 CPU support (not GPU) for intel hd 3000 2nd gen processors???
I hope that you (intel) reconsider. I am asking a direct update of openCL 1.1 which is a CPU support (not GPU). My i7-2640m is still supported and I am still an intel client.
Please see attachment of current OpenCL 1.1 CPU support just to make this more clear.
I hope that intel will be able to offer the OpenCL 1.2 API driver support, on the CPU load, when the development staff have more spare time to deal with older intel processors. Is this task so difficult????
Thank you in advance.
I think I am disapointed with intel development team/support. They say intel hd 3000 does not support openGL 3.3 in windows (only 3.1. is supported) but in Linux ubuntu I have proven them that the intel hd 3000 linux driver does support openGL 3.3. Also Apple OS X has openGL 3.3 support.
Can anyone from intel correct this disapointment that intel support has caused??

If this is easy to achieve I will be over the moon. Otherwise I will be disappointed and probably will never buy an intel processor due to lack of support. If it is not a hassle please support with an updated driver and save intels bad image created by sandy bridge lack of driver features support and lack of continuous development.
Thank you for your reply. It worked.
I did try a few months ago OpenCL™ Runtime 15.1 for Intel® Core™ and Intel® Xeon® Processors for Windows* (64-bit & 32-bit) but it had problems with sandy bridge kernel when I run the Gaps viewer.
I have tried again just now. What I did is uninstall openCL 1.1. Reboot. Install the above driver. Reinstall Gaps viewer.
I run again the CPU OpenCL tests.
It now works. All tests run fine without any problem.
I have no words to describe my appreciation to intel making available for sandy bridge openCL 1.2. (and personally to you)
Just an observation
It should be made available in the latest intel hd 3000 driver too rather than the older openCL 1.1.
I am glad you have responded.
