I think maybe if ckolivas is made aware of this SDK he could pump some code out in a week to get this tested. Author of cgminer for those of you unaware.

cgminer is simply an engine for running open CL KERNELS.

With Intel OpenCL drivers you could simply use existing kernels however for optimal performance you would want an optimized kernel.

I may try this, just got a new SBE board friday.

I bought a motherboard that supports using the built in Sandy Bridge GPU in parallel with added PCI-E GPU's....just in case I would ever want to use that extra GPU + monitor output. Well, if someone can get it mining, let me know! Even 25MH/s is a cool little boost.

Wow. Nice find. So Intel is finally getting on board with GPU acceleration. It likely is very academic but I wonder how much hashing power those crappy integrated GPU have.

The Intel® SDK for OpenCL* Applications now supports the OpenCL* 1.1 full-profile on 3rd generation Intel® Core™ processors with Intel® HD Graphics 4000/2500. For the first time, OpenCL* developers using Intel® architecture can utilize compute resources across both Intel® Processor and Intel HD Graphics. OpenCL* is seamlessly supported by the Intel® Graphics Drivers.

Has anyone tried yet to run BrookGPU or some GLSL code on Intel HD hardware?

Rumor has it that the upcoming Ivy Bridge IGP will support OpenCL.
"The Ivy Bridge GPU adds support for OpenCL 1.1, DirectX 11 and OpenGL 3.1"
See http://www.anandtech.com/show/4830/intels-ivy-bridge-architecture-exposed/5 for more details.

As for why it's so difficult to mine on IGPs, it's because they weren't designed to compute. AMD and Nvidia specifically gave the hardware computational abilities. That's why you cannot mine with an old ATI 3870 or Geforce 7900GTX. They came out before APP and CUDA.

Well, reviews are up for Ivy Bridge, but it looks like the OpenCL driver is still MIA. It might be awhile before we get any mining benchmarks for Ivy Bridge.

At what point would IB (and Haswell) make CPU mining relevant again? Or, more troubling, would it make botnets that much more dangerous? If IVB was good for 10MH/s and Haswell GT3 was good for 20MH/s, it could really add a new wrinkle to the casual mining market. Even though 10-20MH/s might not be a lot, when you're shipping 150M desktop PCs a year even a small percentage of users mining would make a large impact on the network.

As far as I know, the best use for intel HD is to use it for rendering desktop so the rest of GPUs in the rig are dedicated to mining. But that's only useful if you're using your rig for something other than mining as well.

Here is my best guess:

1. CPU only = 1-2 mhash
2. Intel HD Graphics = 3-10 mhash
3. ATI video card = 200+ mhash

Until someone comes up with a miner that actually uses Intel HD... My laptop has a T4400, I think it has Intel 4 series graphics. I'll try your miner to see how many hashes I can do. Incidentally, suggest this to the guy making vanitygen.

This.

OpenCL is currently only supported at the CPU level, in Intel CPUs. It will be supported in future on-dye GPUs of Ivy Bridge, but it isn't supported in Sandy Bridge GPUs atm.

Remember that "OpenCL" doesn't mean that it's GPU-only. You can even compile CUDA to run code on CPU, right now.

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:

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.

I am sure someone who knows more could estimate the speed, but if someone went through all of the work with programming just for it, it might do a few times more then a good CPU.
