What does CPU % mean exactly and what does it mean when you get a CPU ratio warning?

Also what does it mean when there is no CPU % for a running task ?

Mostly used by GPU tasks. In elapsed time the first column is the total elapsed time, the second () is the time the program actually ran.
The CPU % is the percentage of those two times. So 10% means the CPU ran 10% of it's time to feed the GPU.
This is a good way to check if a GPU task is running normally.
