Intel® VTune™ Performance Analyzer 8.0 for Linux* - What's New in Version 8.0 for Linux*

The following are the new main features in the Intel® VTune™ Performance Analyzer 8.0 for Linux*:

• The VTune analyzer is now integrated in the Eclipse 3.1 platform environment for IA-32 architecture and systems with Intel® EM64T processors.
• Authentication for remote sessions -- users without appropriate access rights will not be allowed to access or profile the remote system.
• The VTune analyzer views enable viewing Activity results for IA-32 architectures, Itanium® architectures and systems with Intel EM64T processors. The following views are available:
• Call Graph
• Sampling
• Source View (Source View can be invoked from Call Graph or Sampling views.)

• Support for the latest Intel® processors including Intel EM64T.
• Profiling mixed architecture applications, for example: A user may profile 32-bit applications on Intel EM64T. Profiling applications that contain both Intel EM64T and IA-32 binaries is not supported and each part of these applications should be profiled separately.
• Java* application profiling on systems with all supported Itanium processor-based Linux distributions.
• Support for viewing and analyzing samples collected for up to 4096 processors.
• Support for CPU masking in sampling collection.
• Multi-User Call Graph functionality enabling multiple users to work on the same remote machine simultaneously.
• Call Graph on read-only file systems.
• Support for per CPU buffering in sampling collection allows users of large scale systems to get higher sampling resolution. This feature is useful for users who have experienced missing samples due to a large number of CPUs at a desired sample after value.
• Several install and ease-of-use enhancements
• Automatic filtering of functions Activities with call graph data collection, which have large results.
• Support for Event Ratios for sampling and call graph data collection.
• Automatic driver download and installation. New pre-built drivers are added regularly. If you update your kernel, you can use the get-and-install-driver script (found in /opt/intel/vtune/vdk by default) to install the appropriate driver, or download a driver for your kernel. If a driver does not exist at that site, you will need to build a driver. See the online Help for additional details.
