Finally I would like to get a rendered image of 16000 * 16000 pixels for printing.
However, when trying to render with a size of 8000 * 8000 or more, for example 9000 * 9000, the screen will remain black, even if left for 20 hours, it will remain rendering ....
With 8000 * 8000 rendering time was completed in about 6 hours.
There is a margin for performance on the PC side during rendering.
In arnold answers, I found an answer that arnold can only render up to 8000 in maya. Is it true?

If true, I would like to divide the image into quarters and render every 8000 * 8000 and paste them together.
However, once you start rendering 16000 * 16000, open render view, immediately stop rendering with the Esc key, then render it by a quarter using the render region
The screen remained black.
I use university computers and licenses, universities do not purchase Arnold license additionally, so I can not use batch render.
I am in a hurry to submit my graduation tasks, but I do not come up with a good solution.

Are there any messages in the Log file?

Have you tried using Kick?

Universities can get free Arnold license

The defaultArnoldRenderOptions node has Region Min/Max parameters

I did a 8192x8192 test render. I would suspect the system itself could be the limiting factor.
