Foil 33 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
Distributed memory is, for all intents and purposes, virtually synonymous with message-passing, although the actual characteristics of the particular communication schemes used by different systems may hide that fact.
Message-passing approach:
Tasks communicate by sending data packets to each other.
Messages are discrete units of information and can be distinguished from all other messages (theory).
Parallel tasks use these messages to send information and requests for same to their peers.
