Using Intel® Power Checker to measure the energy performance of a compute-intensive application


Using Intel® Power Checker to measure the energy performance of a compute-intensive application

Intel® Power Checker provides developers with a quick and easy way to evaluate the idle power efficiency of their applications on mobile platforms with Intel® Core™ processor or Intel® Atom™ technology running the Microsoft Windows* operating system. Any compiled language application, especially those designed to run on technology based on Intel® products and Java Framework applications can be analyzed by Intel Power Checker. The checker can be used with or without a supported external power meter.

The Intel Power Checker 2.0 now supports measurement both on battery and with the system plugged into an external AC power source. External power measurement is only supported on Intel® Second Generation Core processors and if the Intel® Power Gadget software has been installed.

For this article, I took a very compute-intensive parallel application that I wrote to solve instances of the logic puzzle Akari. The code uses a backtracking algorithm to explore how to place light bulbs onto a grid under constraints dictated by the rules of the puzzle and the layout of the puzzle instance. Potentially millions of independent tasks can be generated by the code as the solution space is searched by threads executing those tasks. This solution method is eminently ...
