When the analysis run is complete, the Intel® VTune™ Profiler generates a result that is automatically opened in the default viewpoint. The location of the result files is specified in the Configure Analysis window.

A viewpoint typically contains the following elements:

Format	Description
Result Tab	This is a container of all other viewpoint elements. This tab has the same name as the VTune Profiler result file. The result tab name uses the r`@@@`{`at`} format, where `@@@` is an incremented result number starting with 000 and `at` is the analysis type. For example: r004hs is the fifth result run in this project and provides data for the Hotspots (hs) analysis. The Hotspots is the analysis type name. Hotspots by CPU Utilization is the name of the viewpoint selected via the down arrow. Use this arrow to switch to other viewpoints available for this analysis result.
Windows	Each result tab includes a number of windows presenting colleted data from different perspectives. Each window has a corresponding tab. To ease your navigation, some windows are synchronized: when you select an element in a window, the same element is automatically selected in other windows of the same viewpoint. The list of windows depends on the selected viewpoint. Each window has a corresponding context help topic available via F1 button or icon. NOTE: Context help as part of this product help is available on the web only. You may also download a copy of this help from the VTune Profiler documentation archive.
Panes	Each window typically includes two or three panes, such as Call Stack pane, Timeline pane, and others.

Result Tab

This is a container of all other viewpoint elements. This tab has the same name as the VTune Profiler result file. The result tab name uses the r@@@{at} format, where @@@ is an incremented result number starting with 000 and at is the analysis type.

For example:

r004hs is the fifth result run in this project and provides data for the Hotspots (hs) analysis. The Hotspots is the analysis type name. Hotspots by CPU Utilization is the name of the viewpoint selected via the down arrow. Use this arrow to switch to other viewpoints available for this analysis result.

Each window typically includes two or three panes, such as Call Stack pane, Timeline pane, and others.

NOTE:

For a brief overview on a particular viewpoint, click the question mark icon at the viewpoint name.

All the data views make your analysis more convenient and manageable with the following options:

Switch Viewpoints
Use a viewpoint, a pre-set configuration of Intel® VTune™ Profiler's data views, to focus on specific performance problems.
Control Window Synchronization
Correlate the data displayed in the Bottom-up window for each program unit (bottom-up analysis) and in the Top-down Tree window for an overall impact of each element together with its callees (top-down analysis).
View Stacks
Manage the Intel® VTune™ Profiler view to display call stacks for user and system functions and estimate an impact of each stack on the performance metrics.
Manage Grid Views
Explore the mechanisms provided by the Intel® VTune™ Profiler to manage the data format, sort and filter data in the grid views.
Manage Timeline View
Understand how you can filter, sort, and group data in the Timeline pane in Intel® VTune™ Profiler.
Change Threshold Values
If required, modify default thresholds (for example, for CPU Utilization, concurrency, and frame rate histograms) set up by the Intel® VTune™ Profiler based on your system data.
Choose Data Format
Configure the format of presenting the performance data in the grid views.
Group and Filter Data
Analyze the data collected with the Intel® VTune™ Profiler by filtering in areas of interest and grouping the data by specific program units (modules, functions, frame domains, and so on).
View Data on Inline Functions
Configure the Intel® VTune™ Profiler data view to display the performance data per inline functions for applications in the Release configuration.
Analyze Loops
Use the Intel® VTune™ Profiler to view a hierarchy of the loops in your application call tree and identify code sections for optimization.
Stitch Stacks for Intel® oneAPI Threading Building Blocks or OpenMP* Analysis
Use the Stitch stacks option to restore a logical call tree for Intel® oneAPI Threading Building Blocks(oneTBB ) or OpenMP* applications by catching notifications from the runtime and attach stacks to a point introducing a parallel workload.
Search for Data
Use the Find button to search for data in the Bottom-up, Top-down Tree, Source, or Assembly panes.
