Join-calculus

From Wikipedia, the free encyclopedia

The join-calculus is a process calculus developed at INRIA. The join-calculus was developed to provide a formal basis for the design of distributed programming languages, and therefore intentionally avoids communications constructs found in other process calculi, such as rendezvous communications, which are difficult to implement in a distributed setting[1]. Despite this limitation, the join-calculus is equally as expressive as the full π-calculus. Encodings of the π-calculus in the join-calculus, and vice-versa, have been demonstrated[2].

The join-calculus is a member of the π-calculus family of process calculi, and can be considered an asynchronous π-calculus with several strong restrictions[3]:

  • Scope restriction, reception, and replicated reception are syntactically merged into a single construct, the definition;
  • Communication occurs only on defined names;
  • For every defined name there is exactly one replicated reception.

[edit] Languages based on the join-calculus

The join-calculus programming language is based on the join-calculus process calculus. It is implemented as an interpreter written in Ocaml, and supports statically typed distributed programming, transparent remote communication, agent-based mobility, and failure-detection[4].

JoCaml is a version of OCaml extended with join-calculus primitives.

Polyphonic C# and its successor extend C#. Join Java extends Java.
