The Einstein project has an application on their test project (Albert) for running the Binary Radio Pulsar Search (Perseus Arm Survey) tasks in OpenCL on an Intel GPU.

At the Seti project third party programmers are also busy trying to add support for it.

Apropos, I wasn't correct earlier in saying that the CPU didn't need to be detected as OpenCL capable. It does need to be. Which is what is going to be added to the next client that's going to be tested, after we release the new 7.0 client to the public (really soon now).

Collatz has also added an OpenCL Intel app in the last couple of days.

Claggy

So, I finally solved this problem. Firstly, I have enabled intel_GPU in BIOS...

Then I have installed Intel Graphic Drivers as Ageless recommended here.

Then I installed Intel OpenCL SDK as Raistmer recommended here.

Then I connected monitor to intel_GPU (as soon as I connected it to AMD GPU, BOINC did not recognize intel_GPU).

That is. Both intel_GPU and AMD/ATI have been recognized by BOINC Manager and I am able to crunch ati_opencl Collatz applications and "solo_collatz v4.05 (opencl_intel_gpu)"

Thanks for support.

Cheers and NI!

For Science and Shrubberies! Since January 13 2000.

I have installed the graphic (open CL) drivers from here:

Select graphic first.

The only strange thing now is, that all gpu's are GPU 0 now.

I am the BOINC developer who implemented the OpenCL code and I'm trying to understand the problem that caused your Tahiti GPU 0 to be shown a second time under OpenCL GPUs and your Cypress/Hemlock GPU 1 not to be shown under OpenCL GPUs. Please answer the following questions:

[1] What do you mean by Select graphic first?
[2] Which version of BOINC are you running?

You also posted at that

I've tried it right now.

and

The OpenCL lines show twice GPU 0, both times the same card.

[3] What exactly is it that you "tried right now" and
[4] Did you see the same GPU 0 twice before you made that change?

Thank you for your help.

ad 1:
The link given gives the choice to selct different hardware, including cpu. Selecting the cpu does not help, the open cl driver is included in the graphic package. This is what I wanted to say. Product family is graphics, product line is desktop graphics drivers, product name is up to the hardware one has.

ad 2:
BM 7.1.17

ad 3:
In most cases I have access to this system only saturday / sunday and sometimes over night. Monday evening, after some discussions and 2 beers later, I got the system until coming sunday, promising to install the gpu's in another system until friday. This enabled to 'try it right now'.

ad 4:
I did not pay attention to that, all was running fine. If it helps you I can arrange to reset the settings over the weekend. I need to reinstall the GPU's anyway, so its only a tick more work to do.

pls check your PM for additional info.

Cheers,

Hi Alexander,

I think I found the problem in the GPU detection code and fixed it. The odd thing is this bug has been present since April 15 (BOINC 7.0.63) and I am not aware of anyone else reporting it! This bug affects only systems with two or more different AMD GPUs with both CAL and OpenCL.

I see on the Albert@home thread that you said you are running on a 64-bit Windows 7 system. Is that the one you can test on? I'll see if I can get Rom to make you a test build so we can find out if my change does indeed solve the incorrect GPU listings you are seeing.

Cheers,
--Charlie

Correct, it's this machine

(atm not showing the amd-gpu's because they are installed in different pc's)

but as posted earlier not before friday evening.
