Running Benchmarks in Multiple Mode

Intel® MPI Benchmarks provides a set of elementary MPI benchmarks.

You can run all benchmarks in the following modes:

To run the benchmarks in the multiple mode, add the multi- prefix to the benchmark name.

In the multiple mode, the number of groups may differ depending on the benchmark. For example, if PingPong is running on N≥4 processes, N/2 separate groups of two processes are formed. These process groups are running PingPong simultaneously. Thus, the benchmarks of the single transfer class behave as parallel transfer benchmarks when run in the multiple mode.
