Communicating Haskell Processes: Composable Explicit Concurrency Using Monads

Authors: Brown, Neil C.C.

Abstract:

Writing concurrent programs in languages that lack explicit support for concurrency can often be awkward and difficult. Haskell's monads provide a way to explicitly specify sequence and effects in a functional language, and monadic combinators allow composition of monadic actions, for example via parallelism and choice — two core aspects of Communicating Sequential Processes (CSP).We show how the use of these combinators, and being able to express processes as first-class types (monadic actions) allow for easy and elegant programming of process-oriented concurrency in a new CSP library for Haskell: Communicating Haskell Processes.
