Bidir_get
This benchmark measures the bidirectional MPI_Get operation in passive target communication mode. The benchmark runs on two active processes. These processes initiate an access epoch to each other using the MPI_Lock function, get data from the target, close the access epoch, and call the MPI_Barrier function.
