A double click from the function list takes you to the hottest spot in the function.

Tune Threading with Locks and Waits Analysis

Quickly find a common cause of slow performance in parallel programs: waiting too long on a lock while the cores are underutilized during the wait. Profiles like hotspots and locks & waits use a software collector that works on both Intel and compatible processors.

Mine the Data with Timeline Filtering

Select a time range in the timeline to filter out data (e.g., application startup) that masks the information you need. When you select and filter in the timeline, the grid that lists functions using a lot of CPU time updates to show the list filtered for the selected time.

Visualize Thread Behavior

See when threads are running and waiting, and when transitions occur. Balance workloads.

Profile a Running Application

There is no need to stop and re-launch the application when profiling

• Attach to a running process
• Profile the whole system with hardware event sampling and filter out what you need later

Low Overhead / High Resolution Hardware Profiling

In addition to hotspots analysis that works on both Intel and compatible processors, VTune Amplifier XE 2013 has lightweight hotspots analysis that uses the Performance Monitoring Unit (PMU) on Intel processors to collect data with very low overhead. Increased resolution (~1 ms vs. ~10 ms) can find hot spots in small functions that run quickly. Now with optional stack collection to identify the calling sequence.

Advanced Analysis Like Bandwidth

Preset profiles provide an easy “point and shoot” set-up. Choose Hotspot, Lightweight Hotspot, Concurrency, Locks and Waits or more advanced analyses. No memorizing complex event names. Advanced profiles like memory bandwidth analysis, memory access and branch mispredictions find tuning opportunities. Advanced profiles can optionally collect stacks to identify the calling sequence. (Profiles vary by microarchitecture.)

No special builds

Low overhead

Accurate results you can count on.

Command line

Automate regression analysis. Simple remote collection.

System Wide Analysis

Tune drivers, kernel modules and multi-process apps.

Tune Inlining with Call Counts

When a function is called frequently it may make sense to “inline” the code and eliminate the overhead of the function call. VTune Amplifier XE 2013 now provides statistical call count data to help you make better inlining decisions. It also displays profile results on the source code, even if the code is inlined, making it easier to interpret profile results.

Auto Detect Microsoft DirectX* Frames

Got a slow spot in your game play? You don’t want to know where you are spending a lot of time, you want to know where you are spending a lot of time and the frame rate is slow. VTune Amplifier XE 2013 can now automatically detect Microsoft DirectX* frames and filter results to show you what is happening in slow frames. Not using DirectX*? Just define the critical region using the API and frame analysis becomes a powerful tool for analyzing latency.

Better Memory Bandwidth Analysis

VTune Amplifier XE 2013 performs a more accurate memory bandwidth analysis for both reads & writes to cache and memory. It also adds bandwidth analysis for additional processor types.

Intel® Threading Building Blocks

Built-in understanding of parallel programming models means profiling data is described using familiar terms from the source, not with cryptic internal runtime labels.

Low Overhead Java* Profiling

Analyze Java or mixed Java and native code.  Results are mapped to the original Java source.  Unlike some Java profilers that instrument the code, VTune Amplifier XE 2013 uses low overhead statistical sampling with either a hardware or software collector.  Hardware collection has extremely low overhead because it uses the on-chip performance monitoring hardware.

Analyze User Tasks

The task annotation API is used to annotate your source so VTune Amplifier XE 2013 can display which tasks are executing. For example if you label the stages of your pipeline, they will be marked in the timeline and hovering will reveal details. This makes profiling data much easier to understand.

Tune for Intel® Xeon Phi™ Products

Hardware profiling is supported for Intel® Xeon Phi™ products and can be launched from the graphic user interface. It can collect lightweight hotspots and advanced event data and has time markers for correlation of data across multiple cards. Software collection (e.g., locks and waits analysis) is not supported on Intel® Xeon Phi™ products.

Power Analysis

Unlike other tools that measure average power usage, Power Analysis in VTune Amplifier XE 2013 identifies the cause of the wake up. Interrupts are mapped to the IRQ and timers are mapped to the source code with a call stack. This gives you actionable information to reduce / consolidate wake-ups thus reducing power usage by remaining in a low power state for longer periods of time.

Tune MPI Applications

Analyze hybrid applications using MPI and OpenMP. Install on a cluster.

Support for New Processors

VTune Amplifier XE 2013 is constantly adding support for the latest processors. Updates are released shortly after new processors begin shipping.

"Hot keys" Start and Stop Analysis

Add a short cut to quickly launch performance analysis whenever you see your app running slowly.  Program hot keys to start and stop the collection of performance data.
