Intel VTune Amplifier XE is the performance profiler that includes a number of advanced capabilities for developers who need to dig deeper.
Accurate performance data
Without data you are just guessing about the location of the performance bottleneck and can easily waste a lot of time.
Collecting data always has a cost. Intel VTune Amplifier XE keeps the overhead low, making data collection faster and the results more accurate.

A double click from the function list takes you to the hottest spot in the function.
Locks and waits
Quickly find a common cause of slow performance in parallel programs: waiting too long time on a lock while the cores are underutilized during the wait.
Timeline visualizes thread behavior
See when threads are running and waiting and when transitions occur.
System wide Event Based Sampling (EBS)
It uses the on chip PMU to count performance events like cache misses, clock ticks and instructions retired.
Predefined EBS profiles
Easy EBS setup for newer processors! No memorizing complex event names. Profiles vary by micro-architecture.
