Hotspot Navigation

The VTune(TM) Performance Analyzer enables you to locate and view the source or disassembly lines that took a long time to execute. This type of analysis is called hotspot navigation.

To navigate between the hotspots:

  1. Select the column with an event or event ratio you are interested in from the dynamic pane located to the right of the Source pane. To select the column, click any cell in this column.
    The column is highlighted in gray:

  2. Locate and view the hotspots for this particular event/event ratio by using the following source view toolbar buttons:

    Button

    Name

    Purpose

    Go to Largest Hotspot

    Goes to the code line with the highest value for the selected event/event ratio.

    Go to Previous Hotspot

    Goes to the previous (in decreasing order) hotspot for the selected event/event ratio.

    Go to Next Hotspot

    Goes to the next (in decreasing order) hotspot for the selected event/event ratio.

    Go to Smallest Hotspot

    Goes to the smallest non-zero hotspot for the selected event/event ratio.

The button name always includes the event/event ratio name you select. For example, when you select the Total Time column, the button name says Go to the Largest Hotspot for Total Time.

 Tip

You can edit the code in your source file directly from the VTune analyzer. To do that, right-click in the Source pane and select Go to > Editor from the pop-up menu.
