Update: I think that one

Update: I think that one task at 709 seconds was an anomaly. All the rest have been 720-730 seconds, regardless of reserving an additional thread.

We released a BRP4 app

We released a BRP4 app version for Intel HD GPUs over at Einstein.

THX,

running a nice mix now.

@ BM:
The settings needs rework; there is no tab to enable Intel-gpu like it is for AMD and nVidia and the GPU utilization factor of BRP apps has no effect.
GPU-Z says gpu usage between 86 and 98%, Mem usage dedicated 6MB, Mem usage dynamic 375MB. There is headroom left ...

Cheers

That's great news!

As there's been no announcement of the release on the Einstein boards I'll give some feedback here instead.

I've run some tasks on my HD4000 over at Einstein and so far all looks good, 3 have validated. Link to the host

The only small problem is that the task are sent with instructions to use 0.5CPU+1GPU, this has the effect on my system that the GPU load as per GPU-Z is less than 20%. If I free one core by setting my prefs to use 87.5% of the CPUs then the GPU load goes up to about 85-90%.
For now I'm running with an app_config.xml and using 0.5CPU+0.5GPU to run x2 thus reserving one core when there is task available, GPU load is 90-95%.

+1

Not sure why, but it is clear that updating the server to know intel GPU, does not also add the preferences selector. This happened at both SETI Beta and Collatz. So then the admin has to make a second change. Annoying for everybody.

Edit: I forgot to say thanks..... THANKS!

Edit 2: Hmm. Something seems wrong. Can't get work (on einstein):

I have intel GPU selected (and nothing else), and I have all 4 apps selected. According to the server status, all the queues are full of tasks ready to send.

Setting to disable INTEL GPU was added last night.

I honestly don't expect anyone to stress these poor little Intel GPUs with more than one task at a time, so the "GPU utilization factor" was disabled there on purpose.

What does the scheduler log say? Can you give me a hostid that I can look up?

In general, sorry for the

In general, sorry for the somewhat rushed issuing of the Intel GPUs on Einstein. We needed a bit more computing power to help the CPUs crunching through the new Arecibo data, so we decided to just have a try with the Intel GPUs, as the damage, if any, would be very limited.

First of all, thanks to all

First of all, thanks to all who have tested the app so far.

However it seems we could use more testers & feedback, as we see quite a lot of Intel GPU tasks erroring out at Einstein@Home.

I wonder whether this is a driver problem, unfortunately the driver version is not yet recorded on Einstein@Home.

What are the driver versions used here?
