Sergei Winitzki, Declarative concurrent programming with Join Calculus


Abstract: I give an introduction to Join calculus, a declarative formalism for concurrent programming. Join Calculus is a development of Pi-calculus that is higher-level and easier to use in practice. Join Calculus radically improves upon well-known concurrency paradigms such as Actors or CSP. I explain how Join Calculus emerges if we want to improve the Actor model by making actors type-safe, stateless, and automatically managed. I am developing `Chymyst`, a new open-source implementation of Join Calculus as an embedded DSL in Scala. I show concise and fully declarative Chymyst solutions for classic concurrency problems such as the "dining philosophers" or recursive "fork/join".
