Getting Started

This plugin installs the GParallelizer jar files in your app's lib folder and allows you to specify thread pool size in the Config.groovy file. GParallelizer is a Groovy concurrency library, which enables a couple of convenient DSLs and high-level concurrency constructs like actors, data-flow concurrency, concurrent collection processing and more. Check out all the options at (http://code.google.com/p/gparallelizer/).

import static org.gparallelizer.actors.pooledActors.PooledActors.*

final def decryptor = actor {
    loop {
        react {String message->
            reply message.reverse()
        }
    }
}.start()

def console = actor {
    decryptor.send 'suonorhcnysa si yvoorG'
    react {
        println 'Decrypted message: ' + it
    }
}.start()

console.join()

Configuration

environments {
    production {
        gparallelizer.poolsize='5'
    }
    development {
        gparallelizer.poolsize='2'
    }
    test {
        gparallelizer.poolsize='3'
    }
}

If you omit pool size configuration, the value specified for the gparallelizer.poolsize system property will be used instead. If the system property has not been set, a reasonable default based on the number of detected CPU cores will be used.
