Tuple space
From Wikipedia, the free encyclopedia
A tuple space is an implementation of the associative memory paradigm for parallel/distributed computing. It provides a repository of tuples that can be accessed concurrently. As an illustrative example, consider that there are a group of processors that produce pieces of data and a group of processors that use the data. Producers post their data as tuples in the space, and the consumers then retrieve data from the space that match a certain pattern. This is also known as the Blackboard Metaphor.
Tuples Spaces was the theoretical underpinning of the Linda language developed by David Gelernter and Nicholas Carriero at Yale University.
Implementations of Tuple Spaces have also been developed for Smalltalk, Java, Python, Ruby, and Lisp.
