Power Consumption Unavailable

Dear all,

I have installed the Driver Version: 331.20 on a CentOS x86_64 machine which has four (4) TESLA C2050 GPUs and everything seems OK!

The problem is that the power consumption is not shown at the nvidia-smi command! The output is the following:

Is the above output normal??
Any ideas why this is happening??

Best!

Yes, this is normal. Only Kepler-based Tesla (or Quadro) cards support it.

Aha!! Thanks for letting me know!

I thought that all cards were supporting this feature and that something was wrong with my configuration.

It doesn’t look nice though :-(

Best!

AFAIK C2075 (and possibly M2090) also supports power consumption monitoring.

Additionally, you can un-cripple your Kepler-based GeForce cards using: https://github.com/CFSworks/nvml_fix

Does that still work for 331.20? I edited the Makefile to add 331.20, but nvidia-smi segfaults.
