Want to know how green is your Software? Intel® Energy Checker and Yokogawa can help you! The Intel® Energy Checker SDK provides software developers a simple way to measure the energy efficiency (greenness) of their Software by exposing the necessary and basic measurements made by Yokogawa’s highly accurate and reliable Power Analyzers.
|Figure 1.Sample output of pl_gui_monitor utility - In this screenshot, a private version of POVRay* (www.povray.org) was instrumented using the Intel® Energy Checker SDK to compute and expose dynamically it's energy efficiency metrics (pixels rendered per joule consumed and joules consumed per pixel rendered) while rendering a 3D scene (by Gilles Tran © 1993-2009 www.oyonale.com).|
The Intel® Energy Checker API helps Software developers to easily instrument their software to expose metrics of "useful work" done by the software. For example, the amount of useful work done by a video serving application is number of frames processed, for a mail server application the useful amount of work done may be number of emails processed. The core Intel® Energy Checker API consists of five basic functions. These functions include Open, Re-open, Read, Write, and Close. The SDK comes with utilities to measure the energy consumed by the software on Intel server platforms using power analyzers. Power analyzers supported in this SDK include Yokogawa's WT210, WT230, WT500, WT300, WT3000, WT300E, & WT3000E. To learn more about Yokogawa Power Analyzers, please click here.

The WT300 offers high performance and high reliability in a compact package with excellent price value, making it ideal for multiple applications from R&D to manufacturing test. It is the fifth generation of Yokogawa's value series power meter, and the world's best selling power meter.
With 0.02% accuracy and 1MHz bandwidth, the WT3000 delivers where the highest precision measurements are required. It is the industry standard for R&D work on inverters, motor drives, lighting systems and electronic ballasts, UPS systems, aircraft power, transformer testing, and other power conversion devices.
Superior cost performance and compact size make the entry level WT200 Series Digital Power Meters ideal for manufacturing and basic power measurement applications. Offered with One to Three Elements, with Basic Power Accuracy of 0.1% and 100kHz Bandwidth.
The WT3000E is the world’s highest accuracy Power Analyzer with a basic power accuracy of 0.01% of reading + 0.03% of range.
The WT300E series digital power analyzer provides extremely low current measurement capability down to 50 micro-Amps, and a maximum of up to 26 Amps RMS. This instrument is ideal for engineers performing stand-by power measurements, Energy Star®, SPECpower and IEC62301 / EN50564 testing, battery charger and other low-level power measurements.
The WT500 Power Analyzer excels at single-phase and three-phase power measurements. Standard features include a color TFT display and USB interface for communications and memory. The instrument has a basic power accuracy of 0.1%, maximum inputs of 1000 V, 40 A and a measurement bandwidth of DC to 100 kHz.
