Foil 34 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
Message-passing approach:
The overhead is proportional to size and number of packets (more communication means greater costs; sending data is slower than accessing shared memory.).
Message-passing is not cheap: every one of those messages has to be individually constructed, addressed, sent, delivered, and read, all before the information it contains can be acted upon.
In the general case, message-passing will take more time and effort than shared-memory.
