Power Configuration Part 0: Introduction: Yikes, there is a lot that is not documented

I was hoping to write a brief two part overview of how to configure the various power settings for the Intel® Xeon Phi™ coprocessor. It was going to be concise and brief, allowing me to get on to the next topic. Unfortunately, as I dug into the topic further, I discovered that much of it is not very well documented. I found myself essentially writing quite a bit of explanation.

As usual, I am starting off writing this as a series of blogs. At a later point, I will reformat the blogs into a more formal article with any semblance of humor removed.

Here is my outline as it exists so far. This can change as I dig further into the topic.

  1. This very brief introduction and some useful references
  2. Why you might want to adjust your coprocessor’s power management
  3. The micsmc (Intel® MIC System Management Console) graphical interface: power options
  4. The micsmc (Intel MIC System Management Console) command-line interface: power options
  5. The configuration file: power options


Though the documentation is a little sketchy, here is what I found.
