Get Started with
Intel® VTune™
Profiler
 for Windows* OS

Before You Begin

  • Build your application with symbol information and in
    Release
     mode with all optimizations enabled. For detailed information on compiler settings, see the
    VTune
    Profiler
     online user guide    .
    If you do not have your own application, use the
    matrix
     sample application available in
    <
    install-dir
    >\samples\en\C++\matrix
    . You can see sample results in
    <
    install-dir
    >\Projects\sample (matrix)
    .
  • Set up the environment variables:
    <
    install-dir
    >\env\vars.bat
    By default, the
    <
    install-dir
    >
     is:
    • [Program Files]\IntelSWTools\VTune Profiler <
      version
      >
       when installed as a standalone version;
    • [Program Files]\Intel\oneAPI\vtune\<
      version
      >
       for Intel oneAPI Base Toolkit (Beta) installation;
    • [Program Files]\IntelSWTools\system_studio_<version>\VTune Profiler
       for Intel System Studio.
You do not need to execute
vars.bat
 when using
Intel® VTune™
Profiler
 within Microsoft* Visual Studio*.

Step 1: Start
Intel® VTune™
Profiler

Start
Intel VTune
Profiler
 through one of these ways:
Source
Start
VTune
Profiler
Standalone (GUI)
Intel System Studio IDE
  1. Run the
    vtune-gui
     command or run
    Intel® VTune™
    Profiler
     from the
    Start
     menu.
    To start
    Intel® VTune™
    Profiler
     in the Intel System Studio IDE, select
    Tools
    VTune Profiler
    Launch VTune Profiler
    . This sets all appropriate environment variables and opens the standalone product.
  2. Click the menu button in the upper left corner and select
    New > Project...
     .
  3. Specify the project name and location in the
    Create Project
     dialog box.
  4. Click
    Create Project
    .
Standalone (Command line)
Run the
vtune
 command.
Microsoft* Visual Studio* IDE
Open your solution in Visual Studio. The
VTune
Profiler
 toolbar is automatically enabled and your Visual Studio project is set as an analysis target.
You do not need to create a project when running
Intel® VTune™
Profiler
 from the command line or within Microsoft* Visual Studio.

Step 2: Configure and Run Analysis

After creating a new project, the
Configure Analysis
 window opens with these default values:
Setting
Default Value
Target System
Local Host
Analysis Target
Launch Application
Analysis Type
Hotspots
  1. In the
    Launch Application
     section, browse to the location of your application executable file.
  2. Click
    Start
     to run the Hotspots analysis on your host system.

Step 3: View and Analyze Performance Data

When data collection completes,
VTune
Profiler
 displays analysis results in the
Summary
 window. Here, you see a performance overview of your application. Switch to other windows for an in-depth analysis.
The
Insights
 section provides guidance for a deeper analysis.

Next Steps

For a deeper analysis of your system or application, try a different analysis type that may be recommended in the Insights section. Click the Browse button in the
HOW
 pane to view other analysis types.
Analysis Types in Intel VTune Profiler
For the
matrix (sample)
 project, you can explore pre-collected analysis results using any of the following options:
  • Click the
    Help Tour
     button on the Welcome page to launch a sample-based VTune Profiler GUI overview.
  • Use the matrix sample and the associated
    VTune
    Profiler
     Hotspots tutorial     that provides detailed descriptions on the collected results and possible optimizations.
  • Open the
    matrix (sample)
     project and associated result file to explore common performance issues on your own. If the project is not already available in the
    Project Navigator
    , open the project from the
    %USERPROFILE%\My Documents\Vtune\Projects\sample (matrix)
     directory.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
