IntelĀ® MPI Benchmarks User Guide and Methodology Description
This benchmark tests the MPI_Put operation where one active process transfers data to all other processes. All target processes are waiting in the MPI_Barrier call, while the origin process performs the transfers. The completion of the origin process is ensured by the MPI_Win_flush_local_all operation.
