Intel® Xeon Phi™ coprocessor Power Management Turbo Part 2: Hot and Cold Running Silicon

The previous blog in this series, “Intel® Xeon Phi™ coprocessor Power Management Turbo Part 1: What is turbo? And how will it affect my horsepower?” can be found at http://software.intel.com/en-us/blogs/2013/09/26/intel-xeon-phi-coprocessor-power-management-turbo-part-1-what-is-turbo-and-how-will.



Measuring application power consumption on the Linux* operating system

Power consumption is a common and growing concern in large compute installations, whether they be HPC, Cloud or Enterprise: facility power and space limitations are making it increasingly difficult to support the explosive growth of computational needs. Thus we need to dig deeper on how to best reduce power consumption at multiple levels, from hardware to software. In this article I will describe some of the known approaches and tools available to tackle this challenge.

C-States, P-States, where the heck are those T-States?

I had an interesting question come across my desk a few days ago: “Is it still worthwhile to understand T-states?” My first response was to think, “Huh? What the heck is a T-state?”

Doing a little more research, I discovered that, yes, there is something called a T-state, and no, it really isn’t relevant any more, at least for mainline Intel(R) processors.

Let me say this again: T-States are no longer relevant!

Intel® Xeon Phi™ coprocessor Power Management Turbo Part 1: What is turbo? And how will it affect my horsepower?


This is the first of a series of blogs looking at Turbo: What it is and how it impacts software.

This series discusses basic concepts, terminology, how Turbo relates to thermal profiles, when Turbo is useful, and whether Turbo can impact application design.

This is a follow on to my previous series of blogs on power management.

  • IDF2013 - Arrived in San Francisco!

    Just a quick note to say that I arrived this morning in San Francisco to participate in IDF 2013! I find it all very exciting... I am speaking on the tomorrow afternoon on Intel Platform technologies and the cloud, going to use Meshcentral.com as an example of how anyone can leverage Intel technologies to make cloud services better.
