Intel® VTune™ Amplifier
Get Faster Code Faster With Accurate Data & Meaningful Analysis
Whether you are tuning for the first time or doing advanced performance optimization, Intel® VTune Amplifier provides a rich set of performance insight into CPU & GPU performance, threading performance & scalability, bandwidth, caching and much more. Analysis is faster and easier because VTune Amplifier understands common threading models and presents information at a higher level that is easier to interpret. Use its powerful analysis to sort, filter and visualize results on the timeline and on your source.
Quickly turn raw profiling data into performance insights using the graphical interface to sort, filter and visualize data from a local or remote target. Or use the command line i/f to automate analysis.
Easier, More Effective OpenMP* and MPI Multi-Rank Tuning
Fast Answers: Is My OpenMP* Scalable? How Much Faster Could It Be?
Fast Answers: What Will Improve OpenMP* Performance?
Detailed data for each OpenMP region highlights tuning opportunities. The region shown has the potential to run 34% faster if it is rebalanced.
Easier Multi-Rank Analysis of MPI + OpenMP*
VTune Amplifier’s summary view is enriched with a table of the top MPI ranks that will benefit from improved OpenMP* performance.
For hybrid MPI and OpenMP* applications, it is important to explore OpenMP* inefficiency along with MPI communication between ranks. The lower the communication spin time the more the rank was executing (vs. spinning) and the more impact OpenMP* tuning will have on the application elapsed time.
