Intel® MPI Benchmarks User Guide and Methodology Description
This benchmark measures the combination of MPI_Get and MPI_Win_flush_all operations in passive target communication mode. The benchmark runs on two active processes. The target process is waiting in the MPI_Barrier call. Since local completion of the MPI_Get operation at the origin side is semantically equivalent to a regular completion, performance results are expected to be very close to the Unidir_Get benchmark results.
This benchmark is not enabled in IMB-RMA by default. Specify the benchmark name in the command line or use the –include command-line parameter to run this benchmark.
