Intel UHD Graphics? (gen >= 7)

Post by 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

Two questions:
- How do I tell what Intel GPU Gen I have? I'm using Kubuntu 20.04.1. My CPU is i7-8565U
- Where do I put that `enable_guc=2` thing?

Welcome to the F@H Forum k_sze,

The iGPU you have is this: Intel® UHD Graphics for 8th Generation Intel® Processors https://ark.intel.com/content/www/us/en ... 0-ghz.html

Looking up your i7 processor indicates it has UHD Graphics 620 for its integrated GPU. Looking at this article that would make it Gen9 - https://en.wikipedia.org/wiki/Intel_Gra ... tion_(Gen9). Someone else may know the answers for the Linux setup to use this iGPU for folding.

You can set it by creating /etc/modprobe.d/i915.conf
with this content:

Code: Select all

options i915 enable_guc=2

Beignet drivers are for older than 6th gen IGPs, so you'd be ok with the standard Intel opencl drivers.
the enable_guc may be a function only necessary in Debian.
I run OpenCL tasks (non-fah) on Lubuntu/Ubuntu just fine without the line.
