Hi all,

I am trying to run a kubernetes pod that contains AirSim and UnrealEngine inside.
We have three worker nodes, and each has one A100 PCIe GPU. I tried to start ‘Blocks’
environment, the script stops with the following message:

[2023.02.02-12.48.52:053][  0]LogLinux: Warning: MessageBox: Failed to load Vulkan Driver which is required to run the engine.
The engine no longer fallbacks to OpenGL4 which has been deprecated.: Message: 
[2023.02.02-12.48.52:053][  0]Message dialog closed, result: Cancel, title: Message, text: Failed to load Vulkan Driver which is required to run the engine.

[2023.02.02-12.48.52:053][  0]LogCore: FUnixPlatformMisc::RequestExit(1)
airsim_user@test-pod:~$

The error message from vulkaninfo is following.

airsim_user@test-pod:~$ vulkaninfo
ERROR: [Loader Message] Code 0 : loader_scanned_icd_add: Could not get 'vkCreateInstance' via 'vk_icdGetInstanceProcAddr' for ICD libGLX_nvidia.so.0
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.
ERROR at /vulkan-sdk/1.3.204.1/source/Vulkan-Tools/vulkaninfo/vulkaninfo.h:649:vkCreateInstance failed with ERROR_INCOMPATIBLE_DRIVER

My question is

  • Is A100 GPU compatible with vulkan?

Thank you so much,
mm

Let me add the output of nvidia-smi:

airsim_user@test-pod:~$ nvidia-smi

Thank you,

Hi @miwa.egner ,
My GPU is A40, and I have encountered the same problem, did you solve it?

Hi,
Could you provide more details to the setup please? A100 is only supporting Compute while A40 can serve as graphics device with the vGPU driver.

Hi Mariaa, sshaber, thank you for your replies.

Yes, I now found that A100 does not support graphics.
NVIDIA Multi-Instance GPU User Guide :: NVIDIA Tesla Documentation

so this is a feature…

Excuse my reliving a dead thread. I just wanted to point out that the guide given here in the link is for MIG and not for the A100 itself. I’m having the same issues, but only after a driver upgrade, before that the A100 worked with Isaac Gym with graphics.
