| Message-passing approach: |
| Shared memory scales less well than message passing, and, once past its maximum effective bandwidth utilisation, the latency associated with message-passing may actually be lower than that encountered on an over-extended shared memory communications network. |
| There are ways to decrease the overhead associated with message-passing, the most significant being to somehow arrange to do as much valuable computation as possible while communication is occurring. |
