Right up front, I am going to tell you that P-states are irrelevant, meaning they will not impact the performance of your HPC application. Nevertheless, they are important to your application in a more roundabout way. Since most of you belong to a group of untrusting and always questioning skeptics (i.e. engineers and scientists), I am going to go through the unnecessary exercise of justifying my claim.
The code used in examples (Chapters 2-4) in our book can be downloaded from the book's website. We appreciate attribution, but there are no restrictions on use of the code - please use and enjoy! You can use the step by step instructions in the book or if you prefer we've included a Makefile for each of the chapter examples to make life a little easier.

Hi, my name is Taylor Kidd. You many know me from such notables as, “The Beginning Intel® Xeon Phi™ Coprocessor Workshop,” and, “The Advanced Intel® Xeon Phi™ Coprocessor Workshop,” where I mesmerized audiences with over 10 hours of highly technical information.
