Summary

You have completed the Detecting and Resolving Errors with MPI Correctness Checker tutorial. The following is the summary of important things to remember when using this functionality to check your MPI application for errors.

Step	Tutorial Recap	Key Tutorial Take-aways
Configuration options overview	Reviewed the configuration options that control the correctness checking functionality.	You can configure the correctness checking process by adjusting the necessary settings according to your needs.
Resolving the data type mismatch error	Ran an application with the data type mismatch error to detect the cause. Used the correctness checker messages to locate and eliminate the problem.	You can use the correctness checker command-line messages to resolve the reported problems.
Resolving the deadlock error	Ran an application with the deadlock error and created its trace file to detect the cause of the problem. Used the correctness checker messages and Intel® Trace Analyzer Source View to locate and eliminate the problem.	You can: Store source code locations in trace file to easily find problem causes. View and analyze the reported problems using Intel® Trace Analyzer GUI.
