Intel® VTune™ Performance Analyzer for Linux*

Intel® VTune™ 8.0 for Linux*

Overview: Identify and Resolve Performance Bottlenecks

Intel® VTune™ analyzers help locate and remove software performance bottlenecks by collecting, analyzing, and displaying system-wide performance data down to the source level.

VTune Performance Analyzer is a robust, enterprise-grade solution that can handle even 100MB+ executables. It can analyze applications on all sizes of systems based on Intel® processors, from embedded systems through supercomputer systems.

Optimize Linux* applications with the premier tuning tool for Intel® architectures. Use Intel VTune Performance Analyzer for Linux, with a fully-integrated Eclipse*� graphical interface hosted on IA-32 and processors with Intel® Extended Memory 64 Technology (Intel® EM64T) to maximize performance with ease.

Features and Benefits

-  Platform flexibility - TThe latest Intel processors are supported, including Intel® Itanium® 2, 64-bit Intel® Xeon®, and Intel® Pentium® 4 processors, as well as the Intel® Pentium® M processor, a component of Intel® Centrino® mobile technology§
-  This fully Linux*-based solution offers the flexibility of the Eclipse GUI on IA-32 and Intel EM64T, plus a powerful command line interface on IA-32, processors with Intel EM64T, and Itanium-based systems. An Eclipse GUI native on Itanium-based platforms will be available in early 2006.
-  Event-based, system-wide sampling provides developers with the most accurate representation of their software’s actual performance, with negligible overhead.
-  Call graph profiling offers a pictorial view of program flow to help you quickly identify critical functions and call sequences, gaining a high-level, algorithmic view of program execution.
-  Command line capability allows developers the flexibility to collect sampling and call graph data through a choice of scripting languages including PERL*.

What’s New in VTune Performance Analyzer 8.0 for Linux

Fine-tune your code on Intel architecture throughout the development process with the latest Intel VTune Performance Analyzer 8.0 for Linux:
-  Finding your bottleneck is easier than ever. Get a list of the five most time-consuming functions with one simple dialog box. Clicking on a function name displays the source and shows the code that is taking up the most processor time.

-  VTune now supports Linux 2.6 kernels and MontaVista Linux* Carrier Grade Edition. Installation has been greatly simplified and automatically downloads drivers for new kernels.

-  Large system support is even better with the addition of multi-user Call Graph and per-CPU Sampling buffering. Up to 4096 processors are supported.

-  Remote analysis is now more secure. Users without appropriate access rights will not be allowed to access or profile the remote system.

-  Performance tuning in a secure environment just became a whole lot easier. Call Graph can now analyze secure systems with read-only file systems.

-  The VTune environment’s display layouts have been improved based upon user feedback. Finding the right information is now faster and easier than ever. In addition, a new "getting Started" document lets users become productive quickly, with a short "hands-on" tour.

-  VTune is integrated with the popular Eclipse 3.1 development environment, which includes context-sensitive hint panes to help users become effective quickly with important tips and explanations.

-  VTune supports the latest Intel processors, including those with Intel EM64T.
