Intel® VTune™ Amplifier XE is a Performance profiler targeted for analysis of applications running on local Windows*/Linux*/OS X* and remote Linux* target systems. Use this tool to analyze the algorithm choices, find serial and parallel code bottlenecks, understand where and how your application can benefit from available hardware resources, and speed up the execution.
VTune Amplifier XE is available as a standalone product as well as part of the following suites:
Prerequisites
For hardware event-based sampling analysis, make sure you have the sampling driver installed.
For remote analysis, set up your remote Linux target system.
For system requirements, see the product Release Notes.
Step 1: Start the VTune Amplifier
Set up the environment variables:
csh/tcsh users:
source <install_dir>/amplxe-vars.cshbash users:
source <install_dir>/amplxe-vars.sh
<install_dir>is:For root users:
/opt/intel/vtune_amplifier_xe_2016For non-root users:
$HOME/intel/vtune_amplifier_xe_2016
- Launch the VTune Amplifier:
For standalone GUI interface, run the
amplxe-guicommand.For command line interface, run the
amplxe-clcommand.

Step 4: View and Analyze Performance Data
When data collection completes, the VTune Amplifier opens the result in the default viewpoint, which is a preset configuration of windows for an analysis result. You may switch between different viewpoint to analyze the data from different perspectives using different sets of performance metrics.
Start your analysis with the Summary window to get an overview of the application performance and then switch to other windows to explore the performance deeper at the granularity of function, source line and so on.
