Intel doesn't provide any OpenCL SDK. There is no way to "program" the GPU.

That's untrue, starting with sandy bridge and up Intel's IGP supports OpenCL.
Their SDK can be downloaded from here:

Do you read before you claim things are untrue....

Hardware Requirements

Intel® OpenCL SDK 1.5 requires support for the Intel® Streaming SIMD Extensions 4.1 (Intel® SSE 4.1) or higher (Intel SSE 4.2, Intel® Advanced Vector Extensions (Intel® AVX)). SDK works on the CPU's which contain support for the required instruction set extensions:

Mobile and Desktop Products:

See any GPU in there? Intel has long supported OpenCL on CPU ONLY. I will wait for your retraction. If you still don't believe me install the SDK and try to run the samples on an Intel GPU. No need for a miner to prove it is possible just use their samples.

No intel GPU to date supports OpenCL. No ifs, and, or buts. That may change in the future but given the lackluster performance I doubt Intel wants a direct comparison. They would much rather companies buying $8,000 server CPUs.

Im sorry if I was mis-informed in making my claim, but several "white-sheets" from Intel suggests it may be possible.

http://software.intel.com/en-us/articles/introduction-to-intel-opencl-tools/
"There are multiple tools packaged under Intel GPA, for OpenCL we will only use Intel GPA monitor (to collect traces) and Intel GPA Platform Analyzer (to view traces).

Intel GPA Platform Analyzer aligns clocks across all cores to provide uniform timeline for CPU and GPU workloads and running tasks/threads."

Also another interesting find: http://software.intel.com/en-us/forums/showthread.php?t=79766
Intel rep, says it might be possible in the future.

For now all that Intel has said is:
http://software.intel.com/en-us/articles/opencl-sdk-frequently-asked-questions/#9
"11. Will Intel support OpenCL on its new platforms?
Intel will support OpenCL on future tools and platforms. Intel is evaluating when and where OpenCL support will intercept our products, but no announcement has been made."

Again sorry for my mistake, but hopefully OpenCl can be implemented in the near future with Ivy Bridge around the corner.
