Intel Parallel Studio vTune Amplifier
What is VTune Amplifier?
- A tool created by Intel to provide performance analysis on software.
- Offers both a GUI and command-line version for both Windows and Linux
- GUI only for OSX
- Basic features available on both Intel and AMD processors, but advanced features only for Intel
How to use it?
- Available as a standalone unit or part of the following packages:
- Intel Parallel Studio XE Cluster Edition and Professional Edition
- Intel Media Server Studio Professional Edition
- Intel System Studio
Can be run on a local machine
Hotspots
Basic hotspot analysis
Advanced hotspot analysis
Parallelism
Concurrency
- Best for visualizing thread parallelism on available cores, finding areas with high or low concurrency, and identifying serial bottlenecks in your code
- Provides information on how many threads were running at each moment during application execution
- Includes threads which are currently running or ready to run and therefore are not waiting at a defined waiting or blocking API
- Also shows CPU time while the hotspot was executing and estimates its effectiveness either by CPU usage or by Threads Concurrency
