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

Before You Begin

  1. Install Intel® VTune™ Profiler on your Linux* system.

  2. 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.

    You can also use the matrix sample application available in <install_directory>\sample\matrix. You can see sample results in <install-dir>\sample (matrix).

  3. Set up the environment variables:

    source <install-dir>/

    By default, the <install-dir> is:

    • $HOME/intel/oneapi/ when installed with user permissions;

    • /opt/intel/oneapi/ when installed with root permissions.

Step 1: Start VTune Profiler

The Performance Snapshot analysis type is a good starting point for your profiling experience with Intel® VTune™ Profiler. This analysis gives you a general overview of your application performance with recommendations for areas to focus.

  1. In the Launch Application section, browse to the location of your application.

  2. Click the Start to run Performance Snapshot on your application. This analysis presents a general overview of issues affecting the performance of your application on the target 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.

The overview typically includes several metrics along with their descriptions.

Expand each metric for detailed information about contributing factors.

A flagged metric indicates a value outside acceptable/normal operating range. Use tool tips to understand how to improve a flagged metric.
