| Send specifies buffer to be transmitted and receiving process |
| Receive specifies sending process and application storage to receive into |
| Memory to memory copy, but need to name processes |
| Optional tag on send and matching rule on receive |
| User process names local data and entities in process/tag space too |
| In simplest form, the send/recv match achieves pairwise synch event but also collective communication |
| Many overheads: copying, buffer management, protection |
