Cluster-Specific Tuning Commands

To use the MPI tuner in the cluster-specific mode:
  1. Run the following command to create the tuned configuration files in the default
    <installdir>\<arch>\<etc>
    directory:
    > mpitune -hf <hostfile>
    To create configuration files in a different directory, use the
    -odr
    option:
    > mpitune -hf <hostfile> -odr <path_to_result_directory>
  2. Use the
    -tune
    option without an argument to pick up the configuration files from the default directory, or use the path to the results as an argument for
    -tune
    . For example:
    > mpiexec -tune -ppn 8 -n 128 my_app.exe
    > mpiexec -tune <path_to_result_directory> -ppn 8 -n 128
    my_app.exe
