Intel® VTune™ Amplifier offers several tools you can use as you learn, including:
About Tutorials
VTune Amplifier XE 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.
VTune Amplifier for Systems provides tutorials that provide hands-on instructions how to:
Configure and run the Advanced Hotspots analysis on a remote embedded Linux system and view the collected data on the Linux* or Windows* host.
Configure and run the Basic Hotspots analysis on a remote Android* system and view the collected data on the Linux or Windows host.
