Intel VTune Amplifier XE - Optimize Performance and Multicore Scalability

Is your software sluggish? Are you not seeing the performance scaling you expected on multicore processors? How do you diagnose the cause of poor performance and find a solution?

Intel VTune Amplifier XE is our newest performance profiler that builds on the success of Intel VTune Performance Analyzer. It includes all the capabilities of Intel Parallel Amplifier plus a number of advanced capabilities for developers who need to dig deeper.

For advanced performance and greater value, Intel VTune Amplifier XE is also available as part of the Intel Parallel Studio XE 2011 and Intel C++ Studio XE 2011 product suites.

Benefits:

• Accurate performance data - Without data you are just guessing about the location of the performance bottleneck and can easily waste a lot of time.
• Low overhead- Collecting data always has a cost. Intel VTune Amplifier XE keeps the overhead low, making data collection faster and the results more accurate.
• Easy setup - We've added a number of pre-defined performance profiling experiments to the full custom capabilities of earlier versions of Intel VTune analyzer. This makes it easier to get great profiling information without needing to know microarchitectural details.

Fast, Accurate Performance Profiles
Hotspot analysis finds functions using the most time. Click [+] for the call stacks. Double click to see the source.

See the results on your source
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 filters results
Select a time range in the timeline and filter out data (e.g., application startup) that masks accurate results.

Intel Inspector XE Capabilities Timeline Visualizes Thread Behavior
See when threads are running and waiting and when transitions occur.

Profile a Running Application
No need to stop and re-launch the application when profiling

• Attach to Process(Windows only)
• Profile System with EBS (Windows & Linux)

System Wide Event Based Sampling (EBS)
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 microarchitecture.

Opportunities Highlighted
General Exploration turns the cell pink when it suspects a tuning opportunity is present. Hover gives suggestions.
