Why GPUz can not read info from NVIDIA Tesla P100?

[gpww]

I have successfully installed cuda 9.1 and driver for P100 on Windows Server 2012.
However, GPUz can can not read info from NVIDIA Tesla P100 (as attaced pictures)

Does anyone encountered this problem?

I re-installed latest driver for P100 but the problem is still the same.

I am not enterely sure but i think its because gpu—z does not support tesla and quadro cards.

As mentioned in the thread Stefan linked, this is probably due to the card being in TCC mode

Thanks! I understand the problem now.
However, just like the situation mentioned in the discussion: my P100 also refuse to change the mode...

just as the following screen-shot, anyone know why?

I did a little research.
Meanwhile i think NVIDIA-SMI.EXE works only with older Tesla generations.

Current Teslas need to be treated with latest NVFLASH

Run from a CLI
NVFLASH64.EXE --listgpumodes >output.txt

This is a save read operation.
Screen will blank for a few seconds and then come back.
In case of an error message check device manager if GPU has been reactivated.

Grab output.txt from NVFLASH folder and show us the content.


Don't do any write operations with NVFLASH just out of curiosity!

It's done, the mode is TCC. So how to change the mode?

 

[StefanM]

Well, there is only compute mode listed.

If you still want to try:

Set the GPU mode to graphics:
nvflash64.exe --gpumode graphics

Set the GPU mode to compute:
nvflash64.exe --gpumode compute

These are write operations at your own risk!

I have tested with nvflash64.exe --gpumode graphics;

The result showed that mode has been changed successfully. However, the driver is not in correct status:
1. GPU-z still can not read info from these P100
2. nvidia-sim -q say these P100 still in TCC modes
3. the operation system will get stuck if reboot
