All Architectures:

• Low Overhead
  Accurately identify where the program spends time. Sampling is system wide with negligible overhead (typically less than 5 percent).
• Find the Critical Path
  Determine function calling sequences and find the critical path using Call Graph.
• No Recompile Required
  Unlike traditional instrumented profilers that make you recompile or modify your build script, just use your production executables.
• Compatibility
  VTune™ Performance Analyzer supports the latest Intel® processors (Intel® 64 architecture-based processors, Intel® Itanium® processors, multi-core processors...) and a wide variety of Linux* distributions.
• Programming Language and Compiler Independent
  VTune analyzer supports all compilers that follow industry standards (ELF, STABS, DWARF).
• Mixed Java* and Native Code
  Unlike Java*-only analyzers, VTune analyzer tunes mixed Java and native code1.
• Minimal Memory Footprint
  Remote profiling minimizes the performance impact on the target system by running the user interface on a separate system.
• Command Line Capability
  Automate batch operations.
• Large Applications Welcome
  VTune analyzer is a robust solution even with large executables2. If you have a large application with hundreds of thousands of functions, bring it to VTune analyzer.
• Listen to the Compiler's Advice
  An optimizing compiler can do a lot better with just a few tips from you. We've integrated the Intel®Compilers with VTune analyzer to make this easy and very effective.

Large Enterprise and HPC Systems:

• Minimize Traffic in Non-uniform Memory Architecture (NuMA) Systems by storing sampling data in local CPU memory. This is critical to avoid saturating the interconnect fabric and slowing the system under test.
• Designed for High Performance Computing
  Large High Performance Computing (HPC) systems have unique requirements supported by VTune analyzer.

Intel® Itanium® Architecture:

• Eclipse* Based Graphical User Interface
  The easy-to-use Eclipse* based graphical user interface in VTune analyzer is now native on Itanium® architecture.
• Instruction Filtered Events Pinpoint Bottleneck Locations
  Isolate problems like poor pre-fetch and poor memory alignment. Sometimes just choosing an event is not selective enough, because the event can occur both at critical and non-critical times. On Intel Itanium architecture, instruction filtering allows you to collect events only when they occur with a specified op-code.
• Minimize Data Collection with CPU Selection
  Collect only the data you need. CPU selection lets you control exactly where data is collected, from all the processors, only those in your allocation or only the processors you specify. This greatly reduces the amount of data you need to collect.
