Introduction

Intel® VTune™
Profiler
 is a performance analysis tool for users who develop serial and multithreaded applications.
VTune
Profiler
 helps you analyze the algorithm choices and identify where and how your application can benefit from available hardware resources.
Use
VTune
Profiler
 to locate or determine:
  • The most time-consuming (hot) functions in your application and/or on the whole system
  • Sections of code that do not effectively utilize available processor time
  • The best sections of code to optimize for sequential performance and for threaded performance
  • Synchronization objects that affect the application performance
  • Whether, where, and why your application spends time on input/output operations
  • Whether your application is CPU or GPU bound and how effectively it offloads code to the GPU
  • The performance impact of different synchronization methods, different numbers of threads, or different algorithms
  • Thread activity and transitions
  • Hardware-related issues in your code such as data sharing, cache misses, branch misprediction, and others
This document explains how to install and configure
Intel VTune
Profiler
 on a
Linux*
 system.
To install
VTune
Profiler
, you can use:
  • Graphical user interface (GUI) installer: Presents installation options and allows you to choose product components.
  • Silent installer: Uses a single command to install the product in the background.
A 64-bit operating system host is required to use
VTune
Profiler
. You can use
VTune
Profiler
 to analyze both 32-bit and 64-bit applications.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
