Intel® VTune™ Amplifier XE can be installed on Windows*, OS X*, and Linux* platforms and used for analysis of local and remote target systems. Use this tool to analyze the algorithm choices, find serial and parallel code bottlenecks, understand where and how your application can benefit from available hardware resources, and speed up the execution.
VTune Amplifier XE is available as a standalone product as well as part of the following suites:
Prerequisites
For hardware event-based sampling analysis, make sure you have the sampling driver installed.
For remote analysis, set up your remote Linux target system.
For system requirements, see the product .
Step 1: Start the VTune Amplifier
Set up the environment variables with the
amplxe-varsbatch file. For example, if you installed the VTune Amplifier XE using the default directory, type:C:\[Program Files]\IntelSWTools\VTune Amplifier XE 2016\amplxe-vars.bat.Batch file displays the product name and the build number.
Launch the VTune Amplifier:
For standalone GUI interface, run the
amplxe-guicommand.For command line interface, run the
amplxe-clcommand.For the VTune Amplifier integrated into Microsoft Visual Studio* IDE, do any of the following:
From the Start menu, select Intel Parallel Studio XE 2016 > Analyzers > Command Prompt and select the desired environment, for example: IA-32 Visual Studio 2012 Mode.
Open your solution in Visual Studio. VTune Amplifier XE toolbar is automatically enabled and your Visual Studio project is set as an analysis target.
- Configure Microsoft Symbol Server and build your target application in the Release mode with all optimizations enabled.
- Create a VTune Amplifier project (standalone version only):
Click the
![]()
menu button in the right corner and go to New > Project... .Specify the project name and location in the Create Project dialog box.
In the Analysis Target tab, select a target system from the left pane and select an analysis target type from the right pane.
Сonfigure your target: application location, parameters and search directories (if required).
menu button in the right corner and go to New > Project... .In Visual Studio version, VTune Amplifier inherits the Visual Studio settings and uses the application generated for the selected project as your analysis target.
Step 3: Configure Analysis
Switch to the Analysis Type tab.
From the left pane, select an analysis type applicable to your platform and configure analysis options in the right pane.
Click the Start button on the right to launch the analysis.
Step 4: View and Analyze Performance Data
When data collection completes, the VTune Amplifier opens the result in the default viewpoint, which is a preset configuration of windows for an analysis result. You may switch between different viewpoints to analyze the data from different perspectives using different sets of performance metrics.
Start your analysis with the Summary window to get an overview of the application performance and then switch to other windows to explore the performance deeper at the granularity of function, source line and so on.
Training and Documentation
Note
If you have problems viewing VTune Amplifier documentation on the Microsoft Windows Server* 2012 system, adjusting a security setting for the Microsoft Internet Explorer* browser usually corrects the problem. From Tools > Internet Options > Security, add about:internet to the list of trusted sites. Optionally, you can remove about:internet from the list of trusted sites after you are finished viewing the documentation.
