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.  Intel Trace Collector generates trace files of MPI applications, while Intel Trace Analyzer visualizes the MPI application behavior using the generated trace file.

Large trace files are hard to manage: it takes a long time to generate them, a lot of disk space to store them, and they are difficult to analyze with the Intel® Trace Analyzer. For these reasons, you need reduce the trace file size whenever possible. Learn how to reduce trace file size with the Intel® Trace Collector.

About This Tutorial

This tutorial demonstrates a workflow applied to the poisson application. You can ultimately apply the same steps to your own application(s). The options to reduce the trace file size are:

  • Create configuration file
  • Run the application with the -trace-collectives and -trace-pt2pt options
  • Use the MPI_Pcontrol function

After you reduced the trace file size, generate the trace file.

Estimated Duration

10-15 minutes.

Learning Objectives

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

  • Reduce trace file size using various Intel® Trace Collector functionality
  • Generate trace files of reduced size
