can't put nvidia gpu in TCC mode

Question

I am trying to connect to a remote computer with Nvidia Tesla M2070q gpu. I am trying to put the device in TCC mode with this: nvidia-smi -g 0 -dm 0 but gives me the following error : Failed to initialize NVML: Uknown Error

The remote computer has two graphic card, Nvidia Tesla M2070q and some ATI. another information I can't open nvidia control panel via remote desktop, it gives me the following error message: You are not currently using a display attached to an NVIDIA GPU

how can I overcome this ?

Answer 1

Remote desktop uses a virtual graphics driver so the control panel is not accessible. You would need to log in directly. It is not done by the control panel anyway.

This is what I have done. Run a CMD window as Administrator -- right click to launch run as Administrator. CD to C:\Program Files\NVIDIA Corporation\NVSMI. Run nvidia-smi.exe with no arguments to see what the command arguments are. Use -q to query the status. Use -dm to toggle TCC mode. Use separate argument -i to target a specific device. The setting is tentative. Reboot to make it permanent.

Once the TCC settings are in place, you should be able to launch programs from remote desktop that will access the TCC mode driver.
