A shared dataspace model of concurrency-language and programming implications

A language paradigm called shared dataspace is defined that causes computations to be performed using an anonymous, content-addressable communication medium acted upon by atomic transactions. To probe the essence of this paradigm, a relatively simple shared dataspace language called Swarm is defined. An overview is presented of the Swarm language. A formal operational model for the language is given and some of the programming implications and distinctive features of the model and language are discussed. Swarm programming strategies are examined using a series of related example programs
