Overview
Intel® VTune™ Performance Analyzer 9.0 For Windows*

Deliver fast software on the latest 64-bit multi-core 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 Multi-Core 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 multi-core processors.

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.

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.

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

Analyze your code's performance on a variety of Intel® architectures throughout the development process with the latest Intel® VTune™ Performance Analyzer 9.0 for Windows*:

32- and 64-bit support for Microsoft Windows Vista*
32- and 64-bit profiling integrated with Microsoft Visual Studio* 2005
Support for Windows Longhorn Server* Beta (details)
Intel® Quad-Core processor support (details)
Intel® Core™2 Duo, Intel® Core™ Duo, and Intel® Core™ Solo processor support
Dual-Core Intel® Itanium® 2 processor 9000 sequence support
Microsoft .NET* 3.0 support
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.
Note: Features listed as “New” are new since the last major release 8.0. Some have been previewed in minor updates and beta releases.

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
Intel VTune Performance Analyzer 9.0 supports two usage models:
Single system - Perform analysis on software running locally on this system.
Two systems: host and target - Use the controlling host system to remotely analyze software running on the target system.
 
Host System
Target System

Requirements for Single System or Controlling Host System
The hardware and software requirements below apply to a single system used for native analysis, or a host system when using a second system for remote analysis. In both cases, the system referenced is the system upon which Intel VTune Performance Analyzer should be initially installed.

Single or Host System Hardware Requirements
Processors Supported
Intel® Celeron® processor
Intel Celeron D processor
Intel Pentium 4 processor
Intel Pentium 4 processor Extreme Edition
Intel Pentium D processor
Intel Pentium processor Extreme Edition
Intel® Xeon® processor
Intel Xeon processor MP
Intel® Itanium® 2 processor
Low Voltage Intel Itanium 2 processor
Dual-Core Intel® Itanium® 2 processor 9000 sequence (code named Montecito)
Intel Celeron M processor
Mobile Intel Celeron processor
Mobile Intel Pentium 4 Processor - M
Intel Pentium M processor
Intel® Core™ Solo processor
Intel® Core™ Duo processor
Intel XScale® technology-based processors, including the Intel® PXA25x, PXA26x, and PXA27x processors (remote data collection only)
System Memory Requirements on Single System
At least 128 MB of RAM
Disk Space Requirement
Minimum of 117 MB of disk space allocated as follows:
At least 97 MB of available space on a local drive
20 MB of disk space is required for system files on the drive containing the system directory (for example, the C drive)
Note: This additional hard disk space is needed for updating and installing the DLLs and OCXs that Intel® VTune™ Performance Analyzer requires to be in the system directory. Even if you install Intel VTune Performance Analyzer on a hard disk other than the drive containing the system directory, make sure that you have at least 20 MB free on the drive containing the system directory.
