Tutorial: Finding Hotspots on the Intel® Xeon Phi™ Coprocessor - C++ Sample Code

Intel® VTune™ Amplifier for Windows* OS

Legal Information

Discover how to analyze a native application running on an Intel® Xeon Phi™ coprocessor card with the Intel® VTune™ Amplifier and identify the most performance-critical code.

About This Tutorial

This tutorial uses the sample matrix application and guides you through basic steps required to analyze the code for hotspots on the Intel Xeon Phi coprocessor (code name: Knights Corner) based on Intel Many Integrated Core architecture (Intel MIC architecture).

Estimated Duration

10-15 minutes.

Learning Objectives

After you complete this tutorial, you should be able to:

  • Create a VTune Amplifier project.

  • Configure an analysis target for Intel Xeon Phi coprocessor (host launch) target system type and using automation scripts to run it on the card and run it on a card.

  • Configure and run Advanced Hotspots analysis for the Intel Xeon Phi coprocessor.

  • Identify the modules/functions that consumed a lot of CPU time.

  • Analyze the source code to locate the most critical code lines.
