PingPing benchmark is one of the Single
Transfer Benchmarks in PMB. As PingPong, PingPing
measures startup and throughput of single messages,
with the crucial difference that messages are obstructed by oncoming messages.
For this, two processes communicate (MPI_Isend/MPI_Recv/MPI_Wait) with each
other, with the MPI_Isend's issued simultaneously.
