  1. Introduction to Psyclone Gudny R Jonsdottir Center for Analysis & Design of Intelligent Agents Reykjavik University

  2. Psyclone A platform for building hybrid modular, distributed systems Middleware for message passing Mediated publish-subscribe communication with direct module-to-module interaction support Manual & automatic retrieve of old messages

  3. Psyclone Bridges platforms and programming languages Different operating systems Different programming languages C++, Java and C# now; more in the future Distributed (multiple computer) module execution

  4. Psyclone Explicit modularity through whiteboards Semantic message- and stream-based data exchange model Message content: text, xml, … Stream content: audio, video, …

  5. Psyclone messages Message types (subject) Dot-delimited strings, where each segment indicates a node in a tree/graph From most general to most specific Input.Perc.MulM.Interp.Person.LookingAt.Object Output.Plan.Task Output.Plan.Task.InProgress Output.Plan.Task.Done Output.Plan.Act.InProgress Message body Text, preferrably XML

  6. The psySpec Central management of system configuration Whiteboard declaration Module declaration

  7. PsyProbe Web-based monitoring of system at run-time with host:port in web browser Manual messages for debugging purposes

  8. Contexts and Phases Contexts = global states Psylone.System.Ready DiP.Off DiP.On.I-have-turn DiP.On.Other-has-turn Phases = module-specific states Module Starting up Module Ready Module working on ..... Messages specified for each context & phase

  9. AIRPlugs Code libraries that implement the OpenAIR message and routing protocol Easily added to new or existing applications public class PlugExample { JavaAIRPlug m_plug; public PlugExample(String p_name, String p_host, int p_port) { m_plug = new JavaAIRPlug(p_name,p_host,p_port); if( !m_plug.init() ) { System.out.println( p_name + ": Could not connect to the Server on " + p_host + " on port " + p_port + "..." ); System.exit( -1 ); } System.out.println( p_name + ": connected to server on " + p_host + " on port " + p_port + "..." ); m_plug.postMessage("WBPerception","RU.S1.Internal.Perception.OutOfAir","","English",""); } *AirPlugs are available for Java, C++, C#

  10. Preperations for Project 1 Gola cluster: 192.168.101.1-9 We will use 5 and 6 Use Putty.exe to connect to gola Running psyclone psyclone spec=bla.xml port=10001-n
