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.
