Any ideas why my Intel(R) HD

Any ideas why my Intel(R) HD Graphics 530 does not get any work units?

Please see this log maybe it can help identify an issue:

Hi Dmitry from Kiev, welcome

Hi Dmitry from Kiev, welcome to the Einstein@Home project :-).

Here is a small excerpt from the link you provided:-

2016-03-18 03:30:44.9833 [PID=23707]    [version] [HOST#12217768] device name: 'Intel(R) HD Graphics 530'; OpenCL driver version: 20.19.15.4352; platform version: OpenCL 2.0; device version: OpenCL 2.0
2016-03-18 03:30:44.9833 [PID=23707]    [version] driver version 2019154352, min: 0, max: 1018103906
2016-03-18 03:30:44.9833 [PID=23707]    [version] driver version required max: 1018103906, supplied: 2019154352

The last line says that you can't get work with a driver version greater than 1018103906 so your version is being excluded. I don't use Intel GPUs at all (so I'm not sure about the next bit) but I seem to recall that if you allow beta test apps in your project preferences, the driver version check isn't applied. However the risk is that you will get all invalid results with certain driver versions.

You need to look through the thread you have posted in and also this thread as well to see if there are reports of a 'good' driver version for your particular Intel GPU. There may be other threads with information as well.

If you do get it working and returning valid results, please post the driver version you used in the "Problems ..." thread for the benefit of others.

Cheers,
Gary.

Hi Gary! Thank you for the

Hi Gary!

Thank you for the response. I didn't notice the line with driver version.
Actually I thought the reason my Intel GPU is being excluded is the following line:

Quote:
Intel GPU device name: 'Intel(R) HD Graphics 530' doesn't match 'HD Graphics [123]|HD Graphics 40'

I would like to try to allow beta test apps but cannot find this option.
Where should I look for it?

Thank you.

Go here and check "Run test

Go here and check "Run test applications?", then hit update in the BOINC manager.

Best (and welcome!),

Correct. Unfortunately I can quickly summarize that thread for you: there has not been a single Intel driver compatible with the current Skylake GPUs (as yours) and the BRP app. Me and another user have filed bug reports at Intel months ago, but to no avail :/

I haven't been able to pick

I haven't been able to pick up GPU tasks (I disabled CPU ones) on my laptop. I have a i5-4200u (HD 4400 graphics)

I have installed the suggested 15.40 [4th gen] driver for windows 10.. but .. it still isn't picking up work.

Edit: I don't have a dummy plug but I was under the impression that was only required if you have a dedicated GPU... please don't tell me I need to build one of those for a laptop that very much is able to use it's gpu.

I had a quick look and your driver version is too high/new:

2016-03-30 07:03:48.6726 [PID=19058]    [version] [HOST#12225354] device name: 'Intel(R) HD Graphics 4400'; OpenCL driver version: 20.19.15.4380; platform version: OpenCL 1.2; device version: OpenCL 1.2
2016-03-30 07:03:48.6726 [PID=19058]    [version] driver version 2019154380, min: 0, max: 1018103906

Shouldn't be necessary.

Unless I really failed at reading I thought that the one I downloaded was the correct version.... What is the one that works then?

It's probably buried

It's probably buried somewhere in this thread but judging from the scheduler log it should be 10.18.10.3906 (max).

That and 10.18.10.3621 are the "Last known good" - with the emphasis on known.

They are both very old now, and date from the HD 4000 / HD 4600 / Win 7 era - the most recent discussion, with download link for .3621, is in Crunchers Corner: Functional for Einstein Haswell display drivers wanted

I appreciate that the Einstein staff are very busy with important new searches, and that the Intel GPUs are a small fraction of the available computing power - but it's a shame that nobody's been able to get an explanation out of Intel for why their more recent OpenCL drivers are so unreliable for general-purpose computing. It would be a great step forward if the driver/application incompatibility (wherever it lies) could be resolved, so we didn't have to keep referring users into the archives.
