I’m currently working with an NVIDIA RTX 4000 SFF Ada GPU on a system running Ubuntu 24.04 LTS, Kernel 6.8.0-45-generic, using NVIDIA Driver Version 560.35.03 and CUDA Version 12.6. Everything was installed through sudo apt-get install nvidia-open-560
I’ve encountered an issue with the GPU’s power consumption in idle mode.
A) When I first boot up the server, the GPU idles at a low 6 watts, which is expected.
B) After launching a service that utilizes the GPU, the power consumption increases to 13 watts in idle while the service is active.
C) The issue arises when I stop the service: instead of the GPU returning to the previous idle power consumption of 6 watts, it remains at 13 watts, even though the GPU is no longer in use.
This behavior results in unnecessary power consumption when the system should be idling. I’m looking for a solution to force the GPU to revert to its original 7-watt idle state once the service is stopped. Is there a specific command or configuration I can use to reset the GPU’s power state, or could this be related to the driver, kernel, or power management settings? Any advice on troubleshooting or resolving this issue would be greatly appreciated.
Thanks for any hint
