I have a system with Titan V’s where I would really like to monitor the power. I was under the impression that these systems could not do so, after seeing N/A / N/A under power. My NVML tool also reported that it was not supported. However, today I realized that nvidia-smi was returning a power measurement for some GPUs. It seemed like it was active, changing, and tracking. However, it eventually went back to N/A / N/A.
Is this actually supported on Titan V? Is there some special setting that needs to be changed to enable it? Or did I maybe stumble upon a bug?
