Intel VTune Performance Analyzer [9.0 (SSRenewal) (ESD) 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 Core2 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 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. Core2 Duo and Core2 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.

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.

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.

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.

Memory
Single System or Host Only:

• 512 MB of RAM

Target Only:

• 256 MB of RAM

Your application:

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

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.
