Peter, if your BIOS allows

Peter, if your BIOS allows you can use both GPUs for Einstein. Apart from the BIOS setting to use both of them (not all mainboards allow this, because they can't imagine why one would want to) you just (probably still) need a monitor connected to the Intel. I use the VGA input of my regular TFT for this and have it set to display the signal from the nVidia over DVI.

I don't know whether it has

I don't know whether it has been reported before but a few months ago I had to downgrade my Intel 4000 driver to an older version to get the 2.1 working.

The other day I downloaded the latest driver from Intel and they now have 2.1 operating fine.

It is good to be up to date and getting the facility needed.

At the moment I don't get any

At the moment I don't get any new tasks. I didn't change anything. Is there any problem with BRP4 tasks für Intel GPUs?

I'm seeing the same thing, on

I'm seeing the same thing, on all intel_gpu requests - and BRP4 (arecibo, non-GPU) is the only app version available for intel_gpu.

For some reason the feeder is

For some reason the feeder is too slowly re-filling the work array with BRP4 tasks. I tried various configuration options (work array size, weights) to no avail. I'll leave the project running as it is until Monday, then take a look at the feeder code.

If you changed something it

If you changed something it seems to work. I got a couple of new tasks.

Seems to be flowing more freely this morning (famous last words...). Got a dozen on my last request.

I switched my HD4000 to

I switched my HD4000 to Collatz as backup project with ressource share 0. If any of you want to do the same I can recommend the following:

app_config.xml to run 3 WUs concurrently


solo_collatz

0.33
0.01

And edit the files
"mini_collatz_6.04_windows_x86_64__opencl_intel_gpu.config"
"solo_collatz_6.04_windows_x86_64__opencl_intel_gpu.config"

to contain

kernels_per_reduction=2
threads=9

The latter will reduce GPU utilization compared to the standard-configuration, but reduces CPU load to 0. Hence I can comfortably run 3 of these at pretty much no CPU cost to achieve ~98% GPU utilization.
