VTune Amplifier for OpenMP Profiling

Intel VTune Amplifier is a performance analysis tool for users developing serial and multithreaded applications. VTune Amplifier helps to identify where and how an application can benefit from available hardware resources.

VTune Amplifier can be used for several purposes including:

  • Finding the most time-consuming functions in the application

  • Identifying the best sections of code to optimize to get performance benefits

  • Finding synchronization objects that affect the application performance

  • Identifying hardware-related issues in the code such as false sharing, cache misses, branch misprediction, etc

For information on detection of sharing using VTune Amplifier, visit the sub-page on False Sharing Detection using VTune Amplifier.

For information on how to use VTune on NERSC systems, refer to the page on VTune.
