Simple Rendering Question

Hi,
When I render a sequence with Karma let's say 1920 x 1080 px and I tick on "Render all frames with a single process",
it saves out an USD file somewhere before it renders the images.
But why is it render out the USD File again, if I simply want to render double the resolution but all other parameters in the scene remain the same?
Can I avoid this somewhere?

It might be a very newbie question :-)

Thanks Tom

Hi again:

Maybe someone can help me.

I have a scene in Houdini and like to render out with Karma XPU some different shots i.e. Frame 1 - 100, Frame 250 - 400 .....
Therefore I would like to use the TOPnet.

I have a working solution via ROP-Fetch, see attachement.
I just have a concern, if I tick "Render All Frames in a single Process" in the USD-Render ROP
Houdini will start to chache out the USD file first. Depending on the scene, this can take forever and
I have no information about the progress of caching, if it ever starts render images.

So what is a comfortable render solution with some visual feedback of progress and best performance?
