Hi, I'd like to review this proposal. Let's consider the following scenario: - In the MPI_Isend, MPI maps the send buffer into the address space of the receiving process. - In the matching MPI_Recv, the receiving process makes a copy of the mapped send buffer into the receive buffer. - Once the copy is complete, the send buffer is mapped back into the sender address space during the wait/test call. What will happen one tries to access the send buffer in between? Best regards.
