MPI Tuner Modes

The MPI tuner utility can operate in four modes:

  • Cluster-specific. Evaluates a given cluster environment using either Intel® MPI Benchmarks, or a user- provided benchmarking program to find the most suitable configuration of Intel® MPI Library. This mode is used by default.
  • Application-specific. Evaluates performance of a given MPI application to find the best configuration of Intel® MPI Library for a particular application.
