PingPing, PingPingSpecificSource, PingPingAnySource
PingPing, PingPingSpecificSource, and PingPingAnySource measure startup and throughput of single messages that are obstructed by oncoming messages. To achieve this, two processes communicate with each other using MPI_Isend/MPI_Recv/MPI_Wait calls. The MPI_Isend calls are issued simultaneously by both processes. For destination rank, PingPingAnySource uses the MPI_ANY_SOURCE value, while PingPing and PingPingSpecificSource use an explicit value.
