Task 3: Application-Specific Tuning

Now that you have completed the cluster-specific tuning, you can focus on optimizing Intel® MPI Library for your application. You can use the above cluster-specific methods and apply them to your application-specific tuning, with the following modifications:
  1. The layout of your application (such as hosts and process count per host) is set on your
    mpiexec
    command line, outside of
    mpitune
    .
  2. Use your application instead of the micro benchmarks mentioned above.
  3. Use the
    app.xml
    configuration file instead of
    imb.xml
    .
