That's good but not enough. BOINC has to detect it as OpenCL device during startup.

Thank you Claggy. I did what you said and I can do all these steps. But after restarting BOINC (stopped all BOINC processes with Task Manager) Einstein@hope still says: don't need tasks. Perhaps after a while it get tasks. I'll wait and see. Thanks anyhow.

Two possible reasons for that behaviour are:
- a venue that prohibits intel-gpu apps
- a app_config or similar local setup


I don't have an app_config. The iGPU is visible in GPU-Z.
But there is no dummy plug connected as I don't have one for HDMI, I don't have any.

Does the 'Screen Resolution/Change the appearance of your displays' page show at least two displays? Are you sure you selected the Intel GPU one, and not another output from your GTX 780 Ti?

Does the second Display's 'Multiple displays' selection show the Desktop being extended onto it? (I missed that step), it should say 'Extend these displays'.

Claggy


Thank you Claggy!
That last step did the trick. After a BOINC restart, immediately 10 Einstein WU's where downloaded and one is running smoothly now on the iGPU without a monitor or a dummy plug added. So that is not needed. Thanks again for you help.

That now it does, after I executed the last of CLaggy's advice (extend the monitor to it).

A side kick is that I read at GPUGRID that the GTX780Ti runtimes are effected by this and I see indeed that the GPU load of the 780Ti is less. Finding cures for cancer is more important to me than finding proof for Einstein as we know already he is.
But I let it run for a night and see my GPUGRID times. However I am happy that I got yhe iGPU working with the help of the Einstein@home crunchers, as usual. You guys are a real help!

There is a lot of integrated

There is a lot of integrated intel GPU's out there. It would be nice if we could have more of them contribuing for the project.

The server status page reports 2,356 host with intel GPU, but only 504 of them validating tasks

To be fair E@H is not about proving Einstein and general relativity, but more about using gravitational waves as a completely new telescope. Apart from the point of scanning for Pulsars and Gamma Ray Bursts.

But you're right, the main memory bandwidth and L3 cache size occupied for iGPU crunching does affect other projects. I limit this effect by running SIMAP as my main CPU project along the nVidia GPU at POEM or GPU-Grid and the iGPU at Einstein. SIMAP puts next to no additional stress on the memory subsystem (well, significnatly less than Einstein for sure) and thereby minimizes the problem. And it's a nice bio-project, too!

Apropos, seeing how that user has a correctly detected Intel GPU, are there plans to release an Intel_OpenCL_GPU application for the Mac?

Not yet, but that's a good point, in particular given the new MBPs (seems to be what the other thread's OP uses). We'll look into it, shouldn't be too hard to do. I think we're going to deploy a binary on albert soonish...

Any word on OpenCL GPU app for Intel HD on OSX? Over on Collatz, they released an app for that. It works great!

Also, it does not require a monitor dummy plug attached, in case anyone was curious. I have a stack of mac minis all headless, dedicated crunchers.

Sadly that's a matter of the Intel driver, so there's not much we can do about it. I already sent them a message about this long ago, not sure how many more would be needed.

Right. I think apple uses their own OpenCL driver for OSX. So it doesn't have that problem.

FYI: CUDA 5.5.28 is supported on OSX 10.9 but only on > sm_1x architecture GPUs for the time being (a fix is planned).

Update: NVIDIA just released a new CUDA driver for OSX which reportedly supports the sm_1x GPU architecture on 10.9/Mavericks again!

I haven't yet tested that myself...

Best,
Oliver

Are there any news about

Are there any news about supporting Intel GPUs on Mac? SETi@home is working, but I want to crunch here!
