Overview

 Intel® Trace Analyzer and Collector enables you to understand MPI application behavior and quickly find bottlenecks to achieve high performance for parallel cluster applications. Use the Intel Trace Analyzer and Collector to evaluate profiling statistics and load balancing, identify communication hotspots, and increase application efficiency.

 Intel® VTune™ Amplifier XE enables you to find serial and parallel code bottlenecks and speed execution. Use this tool to analyze the algorithm choices, understand where and how your application can benefit from available hardware resources, and identify code sections that may cause unnecessary power consumption.

Both products are installed as part of Intel® Parallel Studio XE Cluster Edition.

To improve performance of some complex applications, it is necessary to analyze their cross-process behavior as well as their single process performance. Intel Trace Analyzer and Collector enables you to analyze communications between processes, while Intel VTune Amplifier helps you find single process performance issues.

About This Tutorial

This tutorial demonstrates a workflow applied to a sample program. The source code is available at <install-dir>/examples/poisson, where <install-dir> is the Intel Trace Analyzer and Collector installation directory.

You can ultimately apply the same workflow to your own applications:

  • Find communication imbalance issues in your application using the Intel® Trace Analyzer charts
  • Find hotspots on the intra-process level of your application using Intel® VTune™ Amplifier XE
  • Review the application

Estimated Duration

20-25 minutes
