CUDA error 700 when rendering a sequence

V-Ray V-Ray GPU Issues
1

Hi guys,
i am rendering this scene:

this is a sequence of cca 350 frames…after 6 or sevent frame we get this error:

we are rendering the scene over 2 cards using DR RT server.
I probably dont have to tell you that it renders blazingly fast to reach the desired quality compared to our 10 node renderfarm :)))
So we need to make this work…however we keep running into problems when trying to render sequences over RT and this is one of them.

Could you please help us debug this?
I can send the scene for inspection…just dotn know to whom :slight_smile: pretty new to RT crowd:)

Cheers
Martin

Let me get someone from the GPU team to help you here…

Best regards,

Hi Martin,

Please upload somewhere the scene and send the link to peter.matanov@chaosgroup.com

It will be helpful to have a bit more information about the setup as well (V-Ray version, driver version, types of GPUs, etc). All of these is printed in the V-Ray log, so if you don’t want to bother checking all these manually you can just send the full V-Ray log altogether with the scene. This will help to make sure we are testing the right thing.

Thanks,
Best,
Blago.

Had the exact same issue today after 240 frames with no issue on a 1k frames render
Just clicked render again to proceed and don’t have any issues since.
Hard part is to recreate the bug I guess as if it render fine for more than 200 frames, it hard to narrow down.
I can send the file tomorrow if needed

Hi guys,
sending the scene to Peter Matanov now.
Unfortunatelly the log is not longe available as i ve opened different scenes on the computer.
This seems like a random bug. I will put the driver versions and the SW versions in the email.
Thanks a lot for your help!

OK just to update this thread , got a reply from Peter Matanov, they have managed to reproduce this and it will be looked into by the GPU team :slight_smile:
Thnaks guys!!!

Lets see how much time it will take to fix it first :).

I think I fixed the issues, will take up some time for the QA team to confirm that (and that I haven’t broken anything else).

We will let you know when the fix gets into the stable nightly builds. If all is okay it will take a week or so. If you are in a hurry, we can make a build sooner than that.

Thanks a lot for your time, the scene and the report !
Best,
Blago.

Thats great news Blago as were quite pushed with deadline…it takes 21 minutes to compute on one computer with RT and it takes 3H47mins to compute over CPU so you can imagine :))
