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:
- The layout of your application (such as hosts and process count per host) is set on yourmpiexeccommand line, outside ofmpitune.
- Use your application instead of the micro benchmarks mentioned above.
- Use theapp.xmlconfiguration file instead ofimb.xml.
