MPI posting meaning

I have google searched the meaning of posting but I haven't found a concrete answer for that. For instance, in the phrase:

once the matching receive is posted

does "posted" here mean that the receive operation has been started or that has been successfully completed?

Any comment is welcome, thanks.

To post a receive operation means to call the corresponding MPI function that initiates the operation. This could be the blocking receive MPI_Recv or it could be the initiation of a non-blocking receive via MPI_Irecv. Same applies to the send operations. Completion comes after posting an operation and it is a separate thing, although blocking MPI operations combine both.
