Test Render & Compiling

[NorthVisualStudio]

Hi

If I do a single frame test render, does the render time and therefore cost include any compiling when using the GPU farm?

Thanks,N

Hi NorthVisualStudio,

Can you please clarify what you mean by 'compiling'?

Thank you,

When I render using my PC and GPU's, before V-Ray starts rendering, is says that it's compiling the GPUs. This seems to happen when rendering a new scene for the first time.

Hi NorthVisualStudio,

Needed some time to clarify how often and when the compiling part happens. It is not often and is only once per scene. Also it is quite fast - around 20 sec. So its cost is not affecting the job cost a lot. But I'll research a bit more and will follow up with you again.

Bests,

I find that it can be up to a 30% increase in overall time from pressing the Render button to completion. You're right, it only happens once per scene however, if I'm sending a single frame to chaos cloud to extrapolate render times for an animation, it skews the numbers.
The simple solution is to send two frames however, I just wanted to check with you first.
Thanks for taking the time to look at it.

Hi NorthVisualStudio,

After further research I can confirm that the process of compiling the GPUs is not part of the cost for the users when rendering a V-Ray GPU job in Chaos Cloud. We are compiling the GPUs as part of the render VM image. This image is loaded on the VM when it is started, and the start-up is excluded from the job cost for the users.

Best regards,
Vladie

That's great, thanks!
