JErlang: Erlang with Joins

ERLANG is an industrially successful functional language that uses the Actor model for concurrency. It supports the message-passing paradigm by providing pattern-matching over received messages. Unfortunately coding synchronisation between multiple processes is not straightforward. To overcome this limitation we designed and implemented JERLANG, a JOIN-CALCULUS inspired extension to ERLANG. We provide a rich set of language features with our joins. We present implementation details of our two alternative solutions, a library and an altered VM. Our optimisations provide JERLANG with good performance.
