Software Power Meters on Microsoft Windows*: A Survey

To get the best and most accurate data about how much energy your computer platform is using during operation you need a hardware power meter, but not everyone can afford one. But what options do you have? The answer is to use a software power meter.

  • Can I still get an Energy Efficient Free Lunch?

    When the semiconductor industry was turning to multicore chips and lowering clock rates, Herb Sutter wrote a seminal article entitled "The Free Lunch is Over: A Fundamental Turn Toward Concurrency in Software." Up to that point software developers relied on the increasing clock speeds (the "free lunch") to give their software a boost in the next generation of processors. Mr.

    OpenSimulator Virtual World Server Case Study (part 3): Virtual World Server Power Savings by Dynamic Physics Tuning

    Use of virtual worlds for training, entertainment, and collaboration is growing. Intel Labs has been researching the scalability of virtual worlds. This series explores some of the design, performance, and execution features of virtual world servers.

  • Using Amdahl's Law for Energy Efficient Performance Estimation?

    While trying to find an answer to my previous question, I stumbled across the paper "Extending Amdahl's Law for Energy-Efficient Computing in the Many-Core Era" (Computer, Dec. 2008, pp. 24-31) by Dong Hyuk Woo and Hsien-Hsin S. Lee (Georgia Institute of Technology). The title had me thinking that this might be an investigation into finding a metric or upper bound on how energy efficient an application could be. It didn't quite turn out to be that simple, but the findings are interesting.

    Accessing Intel® Power Gadget 2.0 library in C++

    With the release of Intel® Power Gadget 2.0 there is now externally callable API’s to extract power information within sections of code. The API layer is a set of libraries and dlls that can be called via C/C#/C++ or via JavaScript and offers the flexibility to build the tool within code sections of an application. Intel® Power Gadget 2.0’s main engine is written as ATL COM that supports Javascript, C++, and C#. The gadget itself is a sample javascript code to use the library.

    How would you define "Energy Efficient"?

    Say your boss comes to you and tells you to ensure that the software project you are working on is energy efficient. (Go ahead, I'll wait while you say it.)

    There are all kinds of ideas to be found on the Power Efficiency Community site on how to accomplish this assignment. What I'd like to know is how you prove to your boss that you have accomplished the task. Or, if you've already optimized the you-know-what out of the application, what do you measure to label your software is energy efficient?
