「一人Scala勉強会 #4」に参加してきました - Actor Model - Islands in the byte stream (legacy)
【第四回】一人Scala勉強会の枠が余っていたので参加してきました。Scalaに興味はあるものの中々手を出せなかったのでいい機会だったと思います。 さて今日はアクターモデルがいまいち分からなかったのでPerlで実装してみることにしました。 まずアクターモデル - GIOの日記からActorでフィボナッチ数を求めるコードをPerlに移植します。 #!perl use 5.14.0; use strict; use warnings; package FibActor { use Mouse; with 'Actor::Fake'; sub act { my($self) = @_; $self->receive(sub { my($self, $n) = @_; say $self->name, ': ', $self->fib($n); }); } sub fib { my($self,
JythonでActor modelプログラミング - DiaryException
ScalaのActorライブラリを使えば、Actor modelに基づく簡単に並行処理プログラムを書くことが出来る。ところで、Wikipedia日本語版のアクターモデルの項は英語版の古い版の訳のようだが、ところどころおかしい。 試しに、2つのActorが数字をカウントするプログラムを書いて実行してみた。 $ scalac ActorTest.scala $ scala ActorTest c1: 1 c2: 1 c2: 2 c1: 2 c2: 3 c2: 4 c2: 5 c2: 6 c2: 7 c2: 8 c2: 9 c2: 10 c1: 3 c1: 4 c1: 5 c1: 6 c1: 7 c1: 8 c1: 9 c1: 10 2つのActorの出力が混ざっている。MacBookPro5,5 (Intel Core 2 Duo)で動かしたので、それぞれのActorが各CPUに配置されて実行

An actor model implementation in C# using TPL DataFlow - Jayway
Post published:November 15, 2013 Post Author:Johan Olsson Post Category:.Net Post Comments:15 Comments The actor model (Wikipedia) An actor is an entity that you can send messages to. In response to a message an actor can do any of the following: * Send messages to other actors * Create new actors * Set behaviour for the next message it receives, (that is, change its internal state) Lets say you h
Actor modelが好きすぎて勢いだけで作ってしまったナニカ - Qiita
メリークリスマス。Elixir Advent Calendar 2013 24日目ですよ。 Elixirが大好きなみんなは、ErlangやRubyにも興味があると思うんですよね。ああ、もしかしたらScalaにも興味があるかもしれませんね。 RubyでElixir/Erlang/ScalaのようなActor modelを実現しようとしたら、Celluloidが定石かなと思いますし、最近はconcurrent-rubyというのも出てきましたが、でもCRubyのマルチスレッドは実質シングルスレッドだったりして（CRuby 2.0時点）、そのままでは計算機リソースを活かすことが難しいです。 というわけで先週日曜に半日かけて一通り作りました。 actoryとは RubyでActor modelや並列処理を実現するためのフレームワークです。actoryはActor model like, concur
Reactor pattern - Wikipedia
The reactor software design pattern is an event handling strategy that can respond to many potential service requests concurrently. The pattern's key component is an event loop, running in a single thread or process, which demultiplexes incoming requests and dispatches them to the correct request handler.[1] By relying on event-based mechanisms rather than blocking I/O or multi-threading, a reacto

Thread per connection vs Reactor pattern (with a thread pool)?
I want to write a simple multiplayer game as part of my C++ learning project. So I thought, since I am at it, I would like to do it properly, as opposed to just getting-it-done. If I understood correctly: Apache uses a Thread-per-connection architecture, while nginx uses an event-loop and then dedicates a worker [x] for the incoming connection. I guess nginx is wiser, since it supports a higher co
How do Functional Reactive Programming and the Actor model relate to each other?
Neither actors nor FRP are about streaming. Actors don't even support external configuration of an output stream. FRP is strongly characterized by its modeling signals and events on a linear timeline, which enables FRP behaviors to compose in a deterministic manner. Actors are strongly characterized by processing messages in non-deterministic order, and have scarcely any compositional properties (
What is the difference between event driven model and reactor pattern?
The reactor pattern is more specific than "event driven programming". It is a specific implementation technique used when doing event driven programming. However, the term is not used with much accuracy in typical conversation, so you should be careful about using it and expecting your audience to understand you, and you should be careful in how you interpret the term when you encounter its use.
