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 for MPI applications, while Intel® Trace Analyzer visualizes the MPI application behavior using the generated trace file.
Besides the regular performance analysis, Intel® Trace Analyzer and Collector can perform correctness checking of MPI applications, which can help you:
  • Find programming mistakes in the application, including potential portability problems and violations of the MPI standard. Normally, these mistakes do not immediately cause problems, but might when switching to different hardware or a different MPI implementation.
  • Detect errors in the execution environment.
About This Tutorial
This tutorial demonstrates the correctness checking workflow applied to sample MPI applications with the following types of errors:
  • Data type mismatch
  • Deadlock
You can ultimately apply the same steps to your own application(s).
Estimated Duration
10-15 minutes.
Learning Objectives
After you complete this tutorial, you should be able to:
  • Run the correctness checker for your own applications
  • Detect and resolve various errors in your applications

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. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
