Intel® VTune™ Amplifier offers several tools you can use as you learn, including:
Note
This document focuses on using the VTune™ Amplifier in the Intel® Parallel Studio XE. You may see minor differences if you installed a different Intel Studio. For more information on product capabilities in your installed Intel Studio, see the studio-specific supplemental documentation in <install-dir>/<Intel_studio>/documentation/.
About Tutorials
VTune Amplifier provides several tutorials that use sample code to explain how to:
Identify where your application is spending time, detect the most time-consuming program units and how they were called.
Identify locks and waits preventing parallelization.
Identify hardware-related issues in your application such as data sharing, cache misses, branch misprediction, and others.

Note
Samples are non-deterministic. Your screens may vary from the screen shots shown throughout these tutorials.
Samples are designed only to illustrate the VTune Amplifier features and do not represent best practices for tuning any particular code. Results may vary depending on the nature of the analysis and the code to which it is applied.
