Get_all_local
This benchmark tests the MPI_Get operation where one active process obtains data from all other processes. All target processes are waiting in the MPI_Barrier call, while the active process performs the transfers. The completion of the origin process is ensured by the MPI_Win_flush_local_all operation. Since local completion of the MPI_Get operation is semantically equivalent to a regular completion, the benchmark flow is very similar to the One_get_all benchmark.
