What's New

Note

This topic provides a list of new features for all existing versions of the Intel® VTune™ Amplifier. Typically, each new version of the product includes all features released in the previous product version unless a feature is specific to a particular market segment. For example, support for Android* application analysis is specific to the mobile and embedded platform segment addressed by the Intel System Studio, so this type of updates is covered in the what's new list for the VTune Amplifier for Systems only.

VTune Amplifier XE 2013 Update 17

  • Updated product toolbar providing quick access to the product documentation with the new Help button and to the Import dialog box with the Import Result button (standalone only)

  • Remote system configuration options provided in the Project Properties: Target tab to specify a path to the VTune Amplifier installed on a remote machine and a path to a remote temporary directory used for storing performance results

  • Updated Event Reference for Intel microarchitectures code name Ivy Bridge and Haswell

VTune Amplifier 2014 Update 1 for Systems

  • Support for all algorithm analysis types (Basic Hotspots, Concurrency, and Locks and Waits) on remote Linux systems

VTune Amplifier XE 2015 Beta

  • Improved OpenMP region analysis with the OpenMP Region grouping level in the Bottom-up window and the Region Instance Duration histogram in the Summary window

    · An option in the graphical and command line interface to import a csv file with the externally collected data into an existing VTune Amplifier result. Importing a csv file does not affect symbol resolution in the existing result.

  • Auto-rebuild of sampling and power drivers at system boot time after Linux* kernel update

  • OS X* host support for performing automated remote collection on other platforms and viewing collected results

  • New TSX Exploration analysis type for 4th generation Intel® Core™ processors based on the Intel microarchitecture code name Haswell

  • Summary window extended with hyperlinks for Top Hotspots and performance metrics navigating to the Bottom-up grid view

  • Call Stack Mode default setting changed from Only user functions to User functions + 1 for better understanding of library usage

VTune Amplifier XE Update 16

  • Graphical interface for remote data collection on Linux* systems via SSH

  • Simplified User API collection setting for native analysis on the Intel® Xeon Phi™ coprocessor

  • Support for external data collection launched from the VTune Amplifier with the Custom collector target configuration option or-custom-collector command line option.

  • An option in the graphical and command line interface to import a csv file with the externally collected data into an existing VTune Amplifier result. Importing a csv file does not affect symbol resolution in the existing result.

  • Support for importing a csv file that does not specify a hostname for the target system but contains time stamps represented in the UTC format. In this case, the VTune Amplifier displays global data (not attributed to specific threads/processes) only.

  • Search functionality for the grid views added to the toolbar

  • Collection data limit option supported for hardware event-based analysis types

  • Usability improvements for the structure of hardware event-based sampling analysis types to introduce cross-CPU basic configurations and separate advanced CPU-specific analysis configurations

  • Grouping options in Timeline pane

  • Event reference help for Intel microarchitecture code name Haswell and Intel® Xeon Phi™ corporcessor (code name: Knights Corner)

  • Overhead and Spin time classification for Microsoft OpenMP* runtimes

  • Support for Hotspots, General Exploration and Bandwidth analysis types on the Intel® Xeon Phi™ coprocessor (except for the user API analysis)

  • GPU analysis for Intel Processor Graphics based on hardware metrics such as Execution Units(EU) Array Active/EU Array Stalled/EU Array Idle, GPU Memory Bandwidth, GPU L3 Cache Misses, and others

  • GPU analysis based on DirectX* pipeline events and used to correlate CPU/GPU usage and identify whether the application is CPU or GPU bound

  • Event Reference documentation separated from the basic help system and delivered per processor
