14. Copyright © 2014–2015 Russel Winder 14 GPars already has single JVM concurrency and parallelism. You can use it from Java as well as Groovy.
15. Copyright © 2014–2015 Russel Winder 15 GPars now has remote objects. Realized by using Netty.
16. Copyright © 2014–2015 Russel Winder 16 Actors Independent processes communicating via asynchronous exchange of messages. Dataflow Operators connected by channels with activity triggered by arrival of data on the channels. Data Parallelism Transform a sequence to another sequence where all individual actions happen at the same time. CSP Operators connected by channels with activity triggered by arrival of data on the channels.
17. Copyright © 2014–2015 Russel Winder 17 Active Objects An object that is actually an actor but looks like a full service object. Agents A wrapper for some shared mutable state. Software Transactional Memory Wrappers for mutable values that uses transactions rather than locks. Fork/Join An toolkit for tree structured concurrency and parallelism.
