Hello!
This is a continue for the topic Installing kit 106 to 8 gpu L40S aws ok but does not launch - #24 by Richard3D

I have now managed to boot Kit 106 on our Stockholm -region VM with the above specs.

It renders but there are issues with the lines.
Please tell me how can we solve this line issues thing?

Also you can see strange white stuff at the eyebrowses and hair all over.
After rendering a litte while, it will take more gpu to use but still its poor and not efficient:

So need to render this at the very same setup ( win11, same drivers and VM ) but just on 1 L40S:

The reason I cannot update the drivers to latest versions is in the very beginning of the original topic:

So that conversation turned into vision of using this AMI product:

I have asked from Ai Enterprise that are the Inception Program credits now 2025 covering the use of those AMI´s since few years ago they did not.

They turned to question to inceptionprogram@nvidia.com
and I have sent to question to there as well.
Waiting for the answer…

I have also asked this same question from AWS support. No answer.

So as it looks like nobdy knows, the answer shall take a long time. That is why I need find a solution for this lines rendering issue.

We are btw building now the render farm :D

Just got an answer from AWS support:

AWS Credits cannot be used to purchase AWS Marketplace subscription “NVIDIA Omniverse GPU-Optimized AMI” and “NVIDIA Omniverse™ Enterprise Workstation (Windows)”.

So what is the best foum to get help for my rendering issue, since I am in Inception Program and Ai Enterprise?
Is it this forum?

We are looking into this bug at the moment. I would start by sending us detailed logs of kit 106, when the lines appear. You are not using our recommended AMI so it hard to advise.

As I mentioned before, you would be better off using a machine with less GPUs and renting more of them to balance it out. You could rent and build a small render farm for this, as you mentioned.

We apologize. It is a bad bug. But it hard to reproduce here. It could be the machine, the motherboard, the drivers, even the specific file.

Can you DM me the complete render ready file and I can test on my dual A6000. Have you tried to do this on your own local dual A600O machine, if you have one?

Thank you very much!
I just sent the USD file and logs and video screens as DM.
Looks like its just impossible to use kit 106 on that 8 L40S gpu VM since now the kit does not boot up 100% but crashes.

I totally understand that the way to do this would be the official AMI VM that you have linked into.
We shall use multi GPU only when we can burn real money on that VM, since Inception Program Credits are not covering that AMI VM. I believe this happens this autumn :D

So I do not ask you to spend so much time on this case Richard.
We will setup the render farm but only after one month when our AWS credits are expired.

About the farm, is it still not a good idea to combine ADA 6000 and RTX A6000 to a same power PC ?

Following your DM to me, and just to update this thread, you MUST select the correct vGPU driver mode. If you want to use an RTX application you will need an RTX vGPU license.

Ok. great. So now I forward this info to aws support and maybe they can help me to change this, right?

Pekka

You can just change this. Just click the RTX one. Unless you have not paid for the right license.

Please can you tell me where this setting is?

looks like it’d be under the NVIDIA Control Panel, assuming the VM has a valid NVIDIA vGPU software license for you to choose from. in your original post, the video you posted at timestamp 0:18 is where you would be able to change it to NVIDIA RTX Virtual Workstation

below are some help docs in case if that doesn’t make sense.

Thank you!
I asked from AWS support how to change this. I tried it but like Richard said, it was not possible without the license..

Pekka

Without the license? So you don’t have an RTX Virtual License? Well you require one for this workflow, so you must get one from Amazon.

Yes, I an working on this with aws support..

Here are the official links for AWS you need to be following

NVIDIA docs on AWS vWS: Using Omniverse AMIs on the AWS Marketplace — Omniverse Developer Workstations
AWS Linux AMI for development: AWS Marketplace: NVIDIA Omniverse™ Development Workstation (Linux)
AWS Linux AMI for enterprise: AWS Marketplace: NVIDIA Omniverse™ Enterprise Workstation (Linux)
AWS Windows AMI for development: AWS Marketplace: NVIDIA Omniverse™ Development Workstation (Windows)
AWS Windows AMI for enterprise: AWS Marketplace: NVIDIA Omniverse™ Enterprise Workstation (Windows)

Perfect, thanks!!
