Overview
Intel® VTune? analyzers help locate and remove software performance
bottlenecks by collecting, analyzing, and displaying system-wide performance
data down to the source level.
Intel® VTune? Performance Analyzer for Linux does this through advanced
profiling technologies. Key highlights include a fully native Linux command line
interface with support for Intel® Itanium® and IA-32 processor-based
applications, as well as Java applications executed on IA-32 processor-based
Linux systems.
Features and Benefits
- Platform flexibility ? The latest Intel processors are supported
including Intel® Itanium® 2, Pentium® 4 processors; Pentium M processor, a
component of Intel® Centrino? mobile technology§; and Intel® Xeon?
processors
- This fully Linux-based solution eliminates the need for an Intel®
VTune? analyzer graphical user interface on a second, networked Windows
system, as required with Intel VTune Performance Analyzer 7.0 and its Linux
remote agents
- 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 graphical high-level, algorithmic
view of program execution based on instrumentation of binary executable
files that produce function calling sequence data
- 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 2.0 for Linux
- The VTune analyzer for Linux provides event-based sampling and
call graph output on the flow of control of Linux applications on Itanium as
well as IA- 32 processors. Source View is now available, allowing developers
to drill down to the source code level.
- The new Call Graph Viewer provides graphical capability for
viewing call graph results. The viewer is a plug-in that installs on and
works with VTune Performance Analyzer 2.0 for Linux.
- Support for several new Linux distributions including their
default versions of kernel, glibc, libstdc++, and glib has been added to
Intel VTune Performance Analyzer 2.0 for Linux. The new Itanium processor
distribution supports Red Hat Linux versions WS 2.1 and ES 2.1. Also, a
newly supported distribution for IA-32 processor-based Linux applications
has been added: SuSE Linux 9.0. (See the product release notes for the most
up-to-date list of supported operating systems.)
- VTune Analyzer Driver Kit allows you to compile the VTune
analyzer driver for your custom kernel environment for the supported
distributions. The kit includes open source driver sources, install scripts,
documentation, and binaries for supported kernels.
- Java application profiling on supported distributions for IA-32
processor-based Linux applications has been added. Sampling and call graph
profiling options can now be enabled for Java applications. Java Virtual
Machines (JVMs) from BEA, IBM, and Sun are supported.
- The new Getting Started tutorial teaches the basic concepts and
functionality of the VTune Performance Analyzer for Linux. It can export
sampling data files for viewing to another VTune Analyzer system as well as
to a VTune Analyzer 7.1 system.
Expose Bottlenecks and Hotspots
VTune Performance Analyzer for Linux offers you a view into the Linux
application, exposing bottlenecks and hotspots in the code, allowing you to
easily pinpoint areas in the code that can be improved. Your Linux application
can gain outstanding performance, providing a competitive advantage.
Supports Intel® Architecture-Compatible Processors
VTune Performance Analyzer for Linux supports the latest Intel processors
including IA-32-based and Itanium-based systems as well as multiple Linux
distributions and kernels. The tool includes the Intel VTune Performance
Analyzer Driver Kit that allows you to compile the VTune analyzer driver for
your custom kernel environment for the supported distributions.
