ReadSample() obtains the number of sampled MSRs from GetNumMsrs(). The ReadSample()function is used to read samples.

Here, the loading of the driver takes place. This library must be initialized at the start of the program by calling IntelEnergyLibInitialize(). 3.2 OverviewĪs the primary API, developers may use Intel® Power Gadget’s EnergyLib32.dll for 32-bit applications or EnergyLib64.dll for 64-bit applications. Although the Intel® Power Gadget API can be used with a sampling frequency ranging from 1 to 1000 milliseconds, the optimal sampling frequency of 100 milliseconds is the default selection on the GUI and is recommended for application developers. Higher the frequency, greater will be the accuracy of the data but poorer will be the performance of the system. Data is acquired from specific MSRs at a fixed sampling frequency.

Sample code called “” to use Intel® Power Gadget’s DLL is available for download at the bottom of this page 3.API of Intel® Power Gadget 3.1 Concept of Samplingįor a good understanding of the API, it is essential to be familiar with the concept of sampling. IPG_Dir: Contains directory in which the DLLs (EnergyLib64.dll used for 64-bit applications and EnergyLib32.dll used for 32-bit applications) were installed.ĭevelopers may utilize the DLL for their 32-bit or 64-bit applications.IPG_Ver: Contains version of Intel® Power Gadget being installed.The installer sets two environment variables on installation: Microsoft Visual C++ 2010 SP1 Redistributable Package will also automatically get installed if not yet installed.įor more information on system requirements and installation, please visit Intel® Power Gadget page 2.Developers’ Tools Net Framework 4 will automatically be downloaded from the Microsoft website if not yet installed in your system.
Follow the installer prompt instructions to complete installation.Download the appropriate Intel® Power Gadget installation package on your system.For more details on the API, please refer to subsequent sections. The DLL serves as a C++ Application Programming Interface (API). This data can be viewed on a Graphical User Interface (GUI) and/or logged for a required duration of time.ĭevelopers may use this data to create their own application by exploiting the Dynamic-Link Library (DLL) used by the Intel® Power Gadget. The supported MSRs are correlated with three MSR functions as described in Table 1. The PROCHOT feature is available only in 3rd Generation Intel® Core™ processors or later. The data is obtained from the Model Specific Registers (MSRs) and energy counters that are available only in 2nd Generation Intel® Core™ or later processors.

Intel® Power Gadget for Windows is an application which presents real-time data about a 2 nd generation or later Intel® Core processor regarding current estimated processor power, package power limit, current processor frequency, base frequency, GT frequency, current temperature, maximum temperature, proc hot (when package temperature exceeds max temperature) timestamps and elapsed time. Latest release also includes support for Windows 10*.Authors: Seung-Woo Kim, Joseph Jin-Sung Lee, Vardhan Dugar, Jun De Vega 1.Introduction 1.1 About Intel® Power Gadget for Windows The API layer is a set of libraries and dlls that can be called and offers the flexibility to build the tool within code sections of an application.
The multi-socket support essentially evaluates the Energy MSR on a per-socket basis and provides an estimate of power draw per socket. In version 3.0 there are additional features that include estimation of power on multi-socket systems as well as externally callable APIs to extract power information within sections of code.

The motivation for the tool was to assist end-users, ISV’s, OEM’s, developers, and others interested in a more precise estimation of power from a software level without any H/W instrumentation. Traditional methods to estimate power/energy usage of the processor has always been a cumbersome task that included special purpose tools or instrumentation on the platform along with third party equipment. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8* will be supported. Windows 7* and 32-bit versions of the Intel Power Gadget for Windows* has ceased development from 3.0.7.
With this release, we are providing functionality to evaluate power information on various platforms including notebooks, desktops and servers.
#Intel power gadget latest mac os
It is supported on Windows* and Mac OS X* and includes an application, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. Intel Power Gadget is a software-based power usage monitoring tool enabled for Intel Core processors (from 2nd Generation up to 10th Generation Intel Core processors).
