Automatic Tuning

Using Regular Expressions with the Intel® MPI Library Automatic Tuner

The Intel® MPI Library includes an Automatic Tuner program, called mpitune.  You can use mpitune to find optimal settings for both a cluster and for a specific application.  In order to tune a specific application (or to use a benchmark other than the default for a cluster-specific tuning), mpitune needs a way to determine the performance from a run of the application.  By default, the runtime of the application will be used.  But depending on the application, this could be inaccurate.  You might want only the time for a specific portion of the application, or you might want a different mea

  • Webinar: Improving Intel® MPI Library Performance with Automatic Tuning and the Intel® Trace Analyzer and Collector

    The Intel® MPI Library includes two utilities for improving MPI performance. The Automatic Tuning utility allows you to tune runtime parameters to match your system and applications. The Intel® Trace Analyzer and Collector allows you to instrument and profile your MPI programs to improve parallelism. In this webinar, I will show you how to use both of these tools to improve your applications’ performance.
