[Question] PowerAPI Measurements for Low/High Performance?

[connorzl]

Hi,

I am a student researcher at Carnegie Mellon University and am using PowerAPI to make power measurements on some Tensorflow Python code.

I am working on a NVIDIA Jetson TK1 Kit (http://www.nvidia.com/object/jetson-tk1-embedded-dev-kit.html), where I have the option of turning on/off cores to change the device's performance level.

When I have all the cores turned on (high performance), PowerAPI suggests that the device is using less power than when I have all the cores turned off (low performance).

Do you have any insights into this result? I would have expected the opposite to occur.

Thank you, Connor Lin
