MPI Basic (Blocking) Receive

• MPI_RECV(start, count, datatype, source, tag, comm, status)

• Waits until a matching (on source and tag) message is received from the system, and the buffer can be used.

• source is rank in communicator specified by comm, or MPI_ANY_SOURCE.

• status contains further information

• Receiving fewer than count occurrences of datatype is OK, but receiving more is an error.
