3 Deliver Faster Code Deliver fast software on the latest 64-bit multicore systems running Microsoft Windows Vista*, Windows* XP or Windows Server*. Locate performance bottlenecks without recompilation and with very low overhead (under 5%). Analyze the results using a graphical interface with strong Visual Studio* and.net integration. Quickly drill down to the source to identify problematic lines of code. Optimize Multicore Performance Intel Thread Profiler included! Not getting the performance you expected after threading your application? Intel Thread Profiler helps you tune multi-threaded code, for optimized performance on today s multicore processors. NEW! Now supports the Intel Core i7 processor NEW! Performance Profiling for Dynamically Generated Code, JavaScript, and Flash. Access to VTune Analyzer s Open Data Model. Microsoft Visual Studio* 2005 integration asmo-na/eng/vtune/ htm Highlights Tune for quad-core with Intel Thread Profiler asmo-na/eng/vtune/ htm Microsoft Windows Vista* compatible asmo-na/eng/vtune/ htm 32- and 64-bit support for Microsoft Windows Vista, Windows XP and Windows Server. Integrated with Microsoft Visual Studio 2005 or use standalone with Visual Studio Supports the latest Intel quad-core processors. Highlights thread overhead and synchronization impact with Intel Thread Profiler. Multi-threading support for load balancing and idle time identification. Works with all compiled languages & compilers (C, C++, Fortran, etc.) Optimize Microsoft.NET applications including C# and Visual Basic. 3 Tune remote Linux* systems from Your Windows* Desktop.

4 Features Speed up your applications by using Intel VTune Performance Analyzer throughout the development process to produce faster, more efficient code. See the Answers on Your Source Source and disassembly views show you exactly which lines of code are taking the most time. 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. Performance data displayed on the source and assembly code asmo-na/eng/ htm Time- and Event-based sampling capability asmo-na/eng/ htm 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. 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. asmo-na/eng/ htm 4

5 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. Compatibility 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 Microsoft.NET including C# and Visual Basic 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. Counter Monitor: Allows real-time performance viewing asmo-na/eng/ htm Tap Into an Expert Knowledge Base with Intel Tuning Assistant Increase productivity using Intel Tuning Assistant to automatically provide advice based on an extensive knowledge base. New Note: Features listed as New are new since the last major release 8.0. Some have been previewed in minor updates and beta releases. Profile JavaScript* and Flash* Code New profiling support in emerging internet browsers and other scriptoriented 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. Intel Tuning Assistant: Provides tuning advice asmo-na/eng/ htm Profile Dynamically Generated Code Many applications today emit their own runtime-generated or justin-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. 5

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. Microsoft Windows Vista* asmo-na/eng/ htm 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 6 Event Rank:view the list of best predictors of performance using machine learning
