Foil 35 Distributed Memory: Some Approaches

From MetaComputing -- MRA Meeting Part I:Concepts and Issues Tutorial for CRPC MRA Meeting at Cornell -- May 7 1996. by Mark Baker, Geoffrey Fox
1 Message-passing approach:
2 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.
3 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.
