Navigation Quick Start

Intel® VTune™ Amplifier provides information on code performance for users developing serial and multithreaded applications on Windows* and Linux* operating systems. VTune Amplifier helps you analyze algorithm choices and identify where and how your application can benefit from available hardware resources.

VTune Amplifier Access

To access the VTune Amplifier in the Visual Studio* IDE: From the Windows* Start menu, choose Intel Parallel Studio XE <version> > Parallel Studio XE <version> with [VS2010 | VS2012 | VS2013].

To access the Standalone VTune Amplifier GUI, do one of the following:

  • From the Windows* Start menu, choose Intel Parallel Studio XE <version> > Intel VTune Amplifier XE <version>.

  • From the Windows* Start menu, choose Intel Parallel Studio XE <version> > Command Prompt > Parallel Studio XE > IA-32 Visual Studio [2010 | 2012 | 2013] mode to set your environment, then type amplxe-gui.

VTune Amplifier/Visual Studio* IDE Integration

Callout A

Use the VTune Amplifier toolbar to configure and control result collection.

Callout B

VTune Amplifier results *.amplxe show up in the Solution Explorer under the My Amplifier XE Results folder. To configure and control result collection, right-click the project in the Solution Explorer and select the Intel VTune Amplifier XE 201n menu from the pop-up menu. To manage previously collected results, right-click the result (for example, r000ge.amplxe) and select the required command from the pop-up menu.

Click the (change) link to select a viewpoint, a preset configuration of windows/panes for an analysis result. For each analysis type, you can switch among several viewpoints to focus on particular performance metrics.

Callout D

Click the buttons on navigation toolbars to change window views and toggle window panes on and off.

Callout E

In the Timeline pane, analyze the thread activity and transitions presented for the user-mode sampling and tracing analysis results (for example, Basic Hotspots, Concurrency, Locks and Waits) or analyze the distribution of the application performance per metric over time for the event-based sampling analysis results (for example, Memory Access, Bandwidth Breakdown).

Callout F

Use the Call Stack pane to view call paths for a function selected in the grid.

Callout G

Use the filter toolbar to filter out the result data according to the selected categories.
