Features

Speed up your applications by using Intel® VTune™ Performance Analyzer throughout the development process to produce faster, more efficient code.
Performance: Advanced Optimization Features
Low Overhead Sampling Profiling Event-based sampling finds your bottleneck with very low overhead (typically less than 5 percent). Identify problems such as cache misses, branch mis-predictions, and bus bandwidth. Because it is system-wide, event-based sampling can be used to tune libraries and drivers as well as application programs. No special builds or instrumentation are required.

See the Answers on Your Source Source and disassembly views show you exactly which lines of code are taking the most time. Click to enlarge Performance data displayed on the source and assembly code
Find the Critical Path Using Call Graph Profiling Call Graph determines calling sequences and graphically displays the critical path. It also shows you the context of the bottleneck. To be effective, you often need to know not only where the application is spending its time, but how it got there. See which functions took the most time to process or were blocked the longest. Click to enlarge Call Graph Profiling – Critical path shown in red. Selecting in the table (light blue row) selects in the graph (light blue box) and scrolls the view to make the function visible.
Identify System Issues with Counter Monitor Quickly identify system level performance issues using the Counter Monitor to track system activity and resource consumption during runtime. For instance, it indicates whether reduced available memory or performance issues associated with file I/O slow down the application.

New In This Release

Profile JavaScript* and Flash* Code
New profiling support in emerging internet browsers and other script-oriented products allow developers working with new JavaScript* or Flash* JIT technologies to analyze their code. Use the VTune analyzer to optimize for scalable performance of these codes on Windows* and Linux* to ensure the best end user experience with your application. VTune analyzer supports profiling JIT’d code when browser vendors add the required support. This enables deep performance analysis of these additional languages:

JavaScript / AJAX

Flash (Action Script)

Check with your browser supplier for details on when their browser will enable support.

Profile Dynamically Generated Code
Many applications today emit their own runtime-generated or just-in-time (JIT) code. New profiling APIs in the VTune analyzer enable performance analysis of dynamic code and allow you to view annotated source code directly from the analysis results.

Access to VTune Analyzer’s Open Data Model
VTune analyzer can now support many different software platforms with performance sampling analysis. Use the new open data model APIs to combine the VTune analyzer's powerful GUI on Windows* or Linux* with data from your custom collector to analyze any application on a wide range of platforms.

Collect data on operating systems not directly supported by the VTune analyzer.

	Supported Windows* Operating Systems
	Supported Linux* Distributions

Collect data on embedded Intel hardware based platforms.

Access to the latest Experimental Technologies
VTune analyzer users have access to the latest experimental performance tuning technologies Intel has to offer. Visit whatif.intel.com and look for Intel® Performance Tuning Utility and Intel® Platform Modeling with Machine Learning. These tools include a number of exciting capabilities including:

Statistical Call Tree - profiles with low overhead to detect where time is spent in your application

Basic Block Analysis - displays hotspots with basic block granularity and generates a control flow graph for advanced analysis of application, even without the source code

Data Access Profiling - identifies memory hotspots and relates them to code hotspots Dependency Plots - visualize the relationships between metrics

Event Rank - view the list of best predictors of performance using machine learning

New More Effective Tuning Methodology Supported
Pipeline stall accounting radically improves tuning by focusing the user on the instances of possible issues (like cache misses) which actually end up mattering. Core™2 Duo and Core™2 Quad processors have greatly enhanced performance analysis capabilities. These processors support more events, higher precision in event location correlation, and a new and wonderful pipeline stall accounting.

New Events For Tuning Multi-core Processors
These events measure parallelism, core sharing of the bus and cache and modified data sharing by threads. They identify opportunities to improve threading, tune multi-core sharing of the bus and cache and optimize cache-line usage.

Compatibility

View the disassembled machine instructions annotated with detailed information on instruction latencies and stalls, as well as suggestions for possible changes to improve software performance.
	Programming Language and Compiler Independent VTune analyzer supports all compilers that follow industry standards including Microsoft and Intel compilers for C, C++ and Fortran . It also supports the most commonly used managed runtime environments like Microsoft .NET (including C# and Visual Basic), and Java* (details).
	Processor Support Supports the latest Intel processors, including Intel® Quad-Core processors.
	*Windows Command Line Capability** Save time by automating sampling with the ability to collect sampling data through the command line, independent of the Intel VTune Performance Analyzer GUI.
	*Tune Remote Linux Systems from Your Windows Desktop** Collect performance data on a remote target Linux system and analyze the results on your controlling Windows system. Or, try the native Linux* version of VTune™ Analyzer.

System Requirements

Usage Models
Intel® VTune™ Performance Analyzer for Windows* supports two usage models:
	*Single Windows System:** Analyze the performance of software running on the local Windows* system.
	*Remote Linux System:** A host computer running Microsoft Windows and the VTune™ analyzer can control event-based sampling and call graph data analysis1 on a remote target machine running a remote data collector (RDC) under a Linux OS. The connection between the target and host computers is TCP/IP. (If your focus is Linux you may wish to consider our native Linux version of VTune Analyzer.)

Hardware Requirements

Type

Requirements

Memory

Single System or Host Only:
128 MB of RAM minimum
(512 MB with Windows Vista*)
1 GB of RAM recommended

Your application:
When running your application with the Call Graph collector, it will require more memory than usual.

Approximate Disk Space

Windows* - Single System or Host Only:
500 MB after installation (about 100MB more during install)

Linux* Remote Data Collectors:
100 MB after installation (about 100MB more during install)

Data Space:
This varies greatly, but for a single or dual processor system, an additional 1 GB on the target system is a good starting point.

Swap Space:
At least double the minimum RAM requirements.

Note: Disk space is needed for updating and installing the DLLs and OCXs that VTune™ Analyzer requires to be in the system directory. Even if you install VTune Analyzer on a disk other than the drive containing the system directory, you will require some free space on the system directory drive. Please see the release notes for details.
