This tutorial demonstrates a basic workflow of analyzing an MPI application, which you can ultimately apply this workflow to your own applications.

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 XE helps you find single process performance issues.
