INTRODUCTION AND PURPOSE:
This article endeavors to provide a single point of reference to Power Management blogs, articles and other resources relevant to the Intel® Xeon Phi™ coprocessor.
Unlike a lot of previous recent blogs, this series is about power management in general. At the very end of the series, I’ll write specifically about the Intel® Xeon Phi™ coprocessor.
I have talked incessantly over the years about power states (e.g. P-states and C-states), and how the processor transitions from one state to another. For a list of previous blogs in this series, and well as other related blogs on power and power management, see the article at [List0]. But I have left out an important component of power management, namely the policy.

Previous blogs on power management and a host of other power management resources can be found in, “List of Useful Power and Power Management Articles, Blogs and References” at http://software.intel.com/en-us/articles/list-of-useful-power-and-power-management-articles-blogs-and-references.
INTRODUCTIONS: TEMPERATURE SENSORS AND THE COPROCESSOR
Writing Energy-Efficient Windows* Store Applications for Mobile Devices [Eng., PDF 753KB]
В настоящее время повсеместно применяются различные мобильные устройства: смартфоны, планшеты, ультрабуки и т. п. Все они работают от аккумуляторов. Время работы от аккумулятора крайне важно для конечных пользователей: всем хочется, чтобы устройство работало без подзарядки как можно дольше.
So exactly which power states exist on the Intel® Xeon Phi™ coprocessor? What happens in each of the power states? Inquiring minds want to know. And since you are, no doubt, aggressively involved in high performance computing (HPC), I am sure you want to know also.
Mobile devices are everywhere today, like smartphones, tablets, UltrabookTM devices, etc. All of them are powered by batteries. Battery life time is critical to end users because everyone wants the battery to last as longer as possible.
This following article was subsidized by Intel and authored by Zebra Partners.
Often considered to be the Achille's heel of portable devices, power management has come a long way. The new breed of Ultrabook™ PCs have pushed battery life and thermal design to a new level. We spoke with Dr. Mike Pearce, Intel Community Manager for Power Efficiency.
Q: Ultrabooks already have fantastic battery life by design, why do I need to worry about it in my application?
