Folding Forum

Hi at all

I have a new Intel NUC Hades Canyon with an AMD Vegas M GPU inside. It runs on Ubuntu 18.04. The CPU works fine. But he don't detect the GPU. I think something with OpenGL is wrong.

Welcome to the folding support forum.

The folding client does not use OpenGL but OpenCL. Support for OpenCL is provided by installing the full proprietary drivers for AMD GPU's and installing OpenCL support for AMD and Ubuntu.

Or maybe the GPU is not whitelisted yet?

AMD Radeon RX Vega M XT
Device Id: 1002 694C
Subsystem Id: 8086 2073

AMD Radeon RX Vega M XL
Device Id: 1002 694E
Subsystem Id: 8086 2073

Probably the same issue most of us have, like mentioned in viewtopic.php?f=16&t=31595

run:

FAH doesn't support Intel GPUs. Have you installed AMD or NV discrete GPUs ... or is that even possible?

This is a new thing Intel packaged with AMD iGPU, so Intel and AMD are friends now

I wonder if this indicates the demise of Intel-branded iGPU?

They've never been game-capable and the NUC is advertised as being game-capable.

FAH has never supported Intel GPUs and (perhaps) they won't ever have to.

Does anybody know what is planned for the transistors that are currently allocated to the Intel IGPU?

Preliminary whitelist added. I'm putting it in the same subclass as a Whistler XT (lacking other details)

Please report assignments and results.

The problem with this kind of device is that it has an integrated (Intel) graphics chip (built on the CPU chip), as well as an external AMD mobile graphics processor.
I presume at this point intel still isn't supported for folding.
You'd have to make sure the AMD chip is the one folding, and not the Intel chip.

Right.

Some laptops already switch between the low-power Intel chip and the high-power chip based on the demands of the graphics. There are a couple of discussions on the troubles they're having. Search the forum for "Optimus"

So far nobody has suggested that there's a "force gaming mode" setting, but there might be.

This shows some ways to modify the GPU settings in the Nvidia Control Panel. I would try to find a setting to always use Nvidia, but perhaps you can just lock the F@H app to always run Nvidia.

Again, this will help if it crashes on startup. It is no help if the GPU is just not capable enough.

While crashing on startup is still a bad thing, a real problem would be if Optimus decided to switch from AMD to Intel in the middle of a WU.

Also, FAH detects the GPUs when the client starts. I don't believe it's dynamic so if it keeps the same setting until FAHClient is restarted, it could dump a lot of perfectly good WUs.

Each GPU can't be manually entered via GPU-index?

The client may not see a GPU in a setup like this if it is inactive. Setting things manually may not work. Users of laptops with low and high power GPU's that are used depending on power usage settings and demand have had problems using the folding client in the past. Often the the problem was that either the usable GPU was not seen at all to run the WU on, or powered off in the middle of processing a WU.
