(moderation:
The latest Boinc beta 7.0.42 finally supports Intel GPUs and Intel has OpenCL drivers ready:
18.12.2012 22:59:20 | | CUDA: NVIDIA GPU 0: GeForce GTX 460 (driver version 310.64, CUDA version 5.0, compute capability 2.1, 1024MB, 951MB available, 1075 GFLOPS peak) 18.12.2012 22:59:20 | | OpenCL: NVIDIA GPU 0: GeForce GTX 460 (driver version 310.64, device version OpenCL 1.1 CUDA, 1024MB, 951MB available, 1075 GFLOPS peak) 18.12.2012 22:59:20 | | OpenCL: intel_gpu GPU 0: Intel(R) HD Graphics 4000 (driver version 9.17.10.2885, device version OpenCL 1.2, 1624MB, 1624MB available, 45 GFLOPS peak) 18.12.2012 22:59:20 | | Version change (7.0.28 -> 7.0.42)
Will E@H make an application for Intel OpenCL GPUs? If yes, when? :)
OpenCL app for Intel HD 4000

This is on the TODO list and will happen...next year :-). I'm not sure we already have a sufficiently large user basis on Albert@Home with an Ivy Bridge, latest BOINC beta and drivers installed, but that's just a question of time. Hopefully the current OpenCL app will work with only minor changes.
Stay tuned

Thank you for the information. Will it be working simultaneously on such Zoo as say a computer with Intel internal GPU plus NVidia and AMD video cards installed in the extension slots?

For some time I had an A8 running with an extra HD5XXX and a nVidia GTX550ti.
Worked fine; I disassembled this system and rearranged it. The HD5xxx and the nVidia can run 2 apps, where the A8 onboard GPU fails with this setting.
Needs a lot of finetuning with the cc_config.xml

Thanks for the info! I didn't expect anything to happen this year. I wish everyone merry Christmas and a happy new year!
Hm I could attach to Albert@Home if there are beta testers needed...
Will we ever see an OpenCL app that will just work on any OpenCL device (even if not at best efficiency)? I really hope that the Intel app doesn't need too much special treatment.

From the BOINC perspective:yes. Whether a GPU is sitting in an extension slot or is sharing a die or package with the CPU is not an important thing for BOINC. There have been reports of installations where the mere presence of the Intel OpenCL driver was inhibiting crunching on the ATI/AMD cards, but thats a defect that should be curable. Already now, OpenCL NVIDIA and OpenCL ATI/AMD drivers are coexisting on systems in perfect harmony and I see no reason why Intel could'nt join in.
