Intel UHD Graphics? (gen >= 7)

[rbpeake]

My laptop has Intel UHD graphics, which is "disabled" by FAH. Why is that?

Thanks.

You need to opt in to using the UHD graphics, see the announcement - viewtopic.php?p=346637#p346637. Intel Gen9 iGPUs are now supported, this period is sort of an open beta test period. If you decide to try this out, current drivers will be required, and you may need to add the option gpu-beta set to try to the GPU folding slot.

Is it recommended to follow Intel's advice and use the latest OEM drivers only?

It is best to get the driver package straight from Intel if you are using Windows. As the version you'll likely get from Microsoft via their update utility may not include libraries that are needed by F@H (OpenCL 1.2). This may be tricky, as you will need to know the core name of your CPU (Comet Lake, for example).

I'll need to do a little bit of homework to find answers for the Linux users, as to where to download the Intel UHD driver packages.

During a (much) earlier state of the Intel beta, I installed the Microsoft drivers for the intel GPU and it worked. Then I quit testing for a while. I tried again a couple days ago and evertthing failed. I'm going to try your suggestion to upgrade the drivers from intel.com. (They may have changed -- I didn't think of that!) Thanks.

While I'm not running any Intel CPU's with the UHD iGPU, I have offered my suggestion. Given a hypothesis that the GPU/iGPU manufacturer's driver package tries to accommodate as many users as possible. Where as the O/S vendor wants the file size of the package they distribute (from their repository) to be as basic as possible. So that it can be delivered quickly with other critical O/S updates to those users who are only crunching numbers and writing documents with their systems.

Just an additional note for those who are using Linux (regardless of distribution): From what I have so far discovered during a quick search on Intel's support site/forum, drivers for Linux will come from the provider of that distribution, where their iGPU's are concerned.

Linux drivers for Intel IGPs, are the intel-opencl-icd and beignet-opencl-icd drivers.
The latter are for very slow and old IGPs (Atom, Celeron, <6th gen Core i, core2duo).
Not sure if FAH recognizes those older IGPs on the client.

I think Beignet doesn't work for FAH ...

I have it running on my notebook, using Debian testing. Buster did not have the relevant packages.

Install instruction is:

Code: Select all

apt install intel-opencl-icd
apt install --no-install-recommends ocl-icd-opencl-dev

I had to set module parameter

Code: Select all

enable_guc=2

for i915 kernel module to have a stable running system, otherwise the GPU would freeze any now and then.

As far as I know beignet is not sufficient for FAH.

And don't forget to set the

Code: Select all

gpu-beta=true
