In Erlang is there any way that a message sender can wait on a response, so it only continues execution once the message has been processed? And I mean something like this: Actor ! DoSomething Continue to this next line of code when DoSomething has been processed I know a callback can be made by sending the Pid of the sender, but is ...
I'm sure this is a very simple question, but embarrassed to say I can't get my head around it: I have a list of values in Scala. I would like to use use actors to make some (external) calls with each value, in parallel. I would like to wait until all values have been processed, and then proceed. There's no shared values being modified...
hi all i'm now to scala. i need a network library with actor model. or the best choise is java.nio? ...
I am just starting to use UML and have came to the following question: Some actors clearly are specialized versions of a natural entity. For example I've got Administrator and User actors which are clearly nothing but different roles of a user, Authorizer and Dispatcher which are services (and are going to be implemented this way). Shou...
Is there a design document for Scala 2.8 Actors, like it is for 2.7? Scala Actors: Unifying Thread-based and Event-based Programming Is there one for Akka? The "Scala Improvement Documents Library" doesn't mention Actors. ...
Do i need to define class for message i want to retrieve on a scala actor? i trying to get this up where am i wrong def act() { loop { react { case Meet => foundMeet = true ; goHome case Feromone(qty) if (foundMeet == true) => sender ! Feromone(qty+1); goHome }}} ...
There are a huge amount of tasks. Each task is belong to a single group. The requirement is each group of tasks should executed serially just like executed in a single thread and the throughput should be maximized in a multi-core (or multi-cpu) environment. Note: there are also a huge amount of groups that is proportional to the number o...
The actor model is nicely described by Gul Agha on his technical report, "Actors: a model of concurrent computation in distributed systems". On page 49 he explains the "become" command: become <expression> After calling "become X", an actor will forward all his messages to another actor's mailbox (X). I'm not sure, however, how this...
Given the following code: class A extends Actor { def act() { loop { reactWithin(1000) { case _ => println("A Message") } } } } and class B extends A { val test = Actor.actor { loop { reactWithin(1000) { case "B" => println("B Message") } } } } Creating an instance of ...
The Actor-model was defined in a 1973 paper by Carl Hewitt, but has been popularized by the Erlang language. I believe the parts of Erlang that aren't self-hosted (written in Erlang) are written in C; BEAM and HiPE are written mostly in C. What are some alternative Actor-model implementations (languages, frameworks, or libraries) that ar...
