I can not select CPU internal GPU and Nvidia's GPU with Ubuntu.

[hryksbt]

Environment

• Smapp version: 0.2.9 | develop
• Node version: v0.x.xx
• OS: Ubuntu 22

Describe the bug

GPU is not appeared.
Intel's internal GPU and Nvidia GPU both.

Steps to reproduce

1. Create PoS data.
2. Select size.
3. Select POS PROCESSOR.

Expected behavior

Showing up all processor including CPU internal GPU and Nvidia GPU.

Actual behavior

CPU internal GPU and Nvidia GPU were displayed until 0.2.8.
But after I start to use 0.2.9, they are not showing up.
I installed latest GPU driver.
This is not occurred with Windows 10 and Mac OS. This is occurred only with Ubuntu.

Attach screenshots or GIF’s of what’s going on if it makes the issue more illustrative.

Logs

Attach app-logs.txt and spacemesh-log.txt

If you can find out the part of the logs that relates to the problem, attach them or paste in code-block.

How to fix

I have no idea.

Hi @hryksbt , Thank you for the issue report. I will provide more information on this week about Ubuntu plugins that will help to smesh with GPU.

Hello @hryksbt

Could you please check the following:

1. https://github.com/spacemeshos/gpu-post/releases/tag/v0.1.27 please download linux build from here, unpack and open terminal in unpacked dir
2. chmod a+x gpu-setup-test
3. export LD_LIBRARY_PATH=.
4. gpu-setup-test --list

And please paste back what the last command outputs. Just please remember about crucial step 3.

[hryksbt]

Hello @pigmej

#./gpu-setup-test --list
Available POST compute providers:
  1: [CPU] CPU

There are no CPU included GPU and Nvidia's GPU.

Hello @hryksbt,
Thanks for the report!
Can you provide your hardware details? Aka your processor and graphic card models?
It may help us to debug and fix the issue.

[hryksbt]

@brusherru Hello,
I have some environment.

Case 1:
Intel Core i5-12600K
This must show up CPU and GPU this is included in CPU.
MSI mother board. Z690 chipset. DDR4.

Case 2:
Intel Core i3-12100
This must show up CPU and GPU this is included in CPU.
MSI mother board. Z690 chipset. DDR4.

Case3:
Intel Core i7-11800M
Nvidia GeForce RTX3080 Laptop
This must show up CPU, GPU this is included in CPU and Nvidia's GPU.
This laptop is made by MSI. DDR4.

@hryksbt if possible, could you please run the command from the above with export VK_LOADER_DEBUG=all and paste the output?

I'm curious about the exact error on your system.

Additionally, if you could install vulkantools (if ubuntu based system, then sudo apt install vulkan-tools) and then paste the output of vulkan-info

Thanks.

[pigmej]

@hryksbt anyway if you could double check with most recent gpu-post release?: https://github.com/spacemeshos/gpu-post/releases/tag/v0.1.28

[hryksbt]

I downloaded 0.1.28 then executed gpu-setup-test --list, that returned same.
I set export VK_LOADER_DEBUG=all too.

Result:

Available POST compute providers:
  1: [CPU] CPU

Then I installed Valkan-Tool, But I got same result.

[pigmej]

@hryksbt did you remember to export LD_LIBRARY_PATH=. ?

[hryksbt]

@pigmej Of course. If I don't use export LD_LIBRARY_PATH=. , this command cannot run as you know.
I think this feature must refactor such as mining stop issue.

[pigmej]

You should be stil able to use cuda. (apt install cuda).

But yes we're checking why Vulkan based provider is no longer working on Ubuntu.

[hryksbt]

@pigmej I didn't need cuda until 0.2.8 version. You should check what affect to hide Vulkan and Nvidia.
All my environments occurred same issue. They are using different CPU and GPU.
I think every people who are using Ubuntu getting same issue.
If you want, I can give you Teamviewer ID/Password. You can debug on my PC.
Please give me DM if you want. I am "Be" in discord.
Thanks.

[pigmej]

Ok.

The issue was nvidia drivers, for hybrid cards 525+ driver is needed. We will update the readme.

Checked with 0.1.28 and now all is good.

[hryksbt]

@pigmej Thank you for your kindly support.
I could understand this must match with cuda version.
Have a nice day!
