Intel® VTune™ Amplifier

Introduction

Intel® VTune™ Amplifier is a performance analysis tool for users developing serial and multithreaded applications. VTune Amplifier helps you analyze the algorithm choices and identify where and how your application can benefit from available hardware resources.

Use the VTune Amplifier to locate or determine the following:

VTune Amplifier can be installed on Windows*, macOS*, and Linux* platforms and used for analysis of local and remote target systems. Default installation directories are:

On Windows systems, VTune Amplifier integrates into Microsoft Visual Studio* software and is also available as a standalone GUI client. On Linux and macOS systems, VTune Amplifier works exclusively as a standalone GUI client. On macOS, you can set up your project, run remote analysis, and view the data collection result on the host. Local macOS analysis is not supported. On all supported systems, you can use the command line interface (amplxe-cl) for collecting data and performing regression testing.

Intel System Studio provides energy analysis capabilities for reviewing power consumption of your application or system with the Intel SoC Watch command line utility. You can use the VTune Amplifier as a viewer for the energy analysis by importing the collection results (*.pwr) into the GUI version. Standalone and Intel Parallel Studio version of the VTune Amplifier also supports import of the Intel SoC Watch results.

Key Features

This table summarizes availability of the key VTune Amplifier types of analysis per host and remote target platform:

¹Preview only; ²Intel HD Graphics and Intel Iris® Graphics only; ³EBS analysis only

VTune Amplifier provides features that facilitate the analysis and interpretation of the results:

CAUTION

Because the VTune Amplifier requires specific knowledge of assembly-level instructions, its analysis may not operate correctly if a program (target) is compiled to generate non-Intel architecture instructions. In this case, run the analysis with a target executable compiled to generate only Intel instructions. After you finish using the VTune Amplifier, you can use optimizing compiler options that generate non-Intel architecture instructions.
