Chord (concurrency)
A chord is a concurrency construct available in Polyphonic C♯ and Cω inspired by the join pattern of the join-calculus. A chord is a function body that is associated with multiple function headers and cannot execute until all function headers are called. Synchronicity Cω Cω (pronounced "see omega"; usually written "Cw" or "Comega" whenever the "ω" symbol is not available) is a free extension to the C# programming language, developed by the WebData team in Microsoft SQL Server in collaboration with Microsoft ... defines two types of functions synchronous and asynchronous. A synchronous function acts like a standard function in most Object-Oriented Language, upon invocation the function body is executed and a return value may or may not be returned to the caller. An asynchronous function acts similar to a function that returns void except that it is guaranteed to return immediately with the execution being done in a separate thread.

Join-calculus
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. Despite this limitation, the join-calculus is as expressive as the full π-calculus. Encodings of the π-calculus in the join-calculus, and vice versa, have been demonstrated. The join-calculus is a member of the π-calculus family of process calculi, and can be considered, at its core, an asynchronous π-calculus with several strong restrictions: *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. However, as a language for programming, the join- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
