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.
This tutorial helps you improve the application performance by removing serialization. When your application is serialized, much time is spent on communication of processes slowing down the execution. Learn how to detect and remove serialization in your application using Intel® Trace Analyzer.
About This Tutorial
This tutorial demonstrates a workflow applied to a sample program. You can ultimately apply the same workflow to your own application(s):
  • Analyze the application with the help of the Intel® Trace Analyzer charts, to find communication problems
  • Detect serialization in communications between processes
  • Resynchronize the processes to remove serialization
  • Review the application
Estimated Duration
10-15 minutes
Learning Objectives
After you complete this tutorial, you should be able to:
  • Detect serialization in your application with the help of the Intel® Trace Analyzer
  • Improve overall performance

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
