Mapping MPI Calls

The essence of our parallel overhead compensation scheme is that whenever two processes interact with each other, the receiver is made aware of the sender's delay value, or how much sooner the communication operation would have taken place in the absence of instrumentation. We have discussed above how this scheme operates for synchronous message communication operations using MPI_Send and MPI_Recv. In this section we explore how other MPI calls can be made aware of remote delays.
