introduction about gc with globus toolkit
Introduction about GC with Globus Toolkit
  • GC: enables the sharing, selection, and aggregation of geographically distributed heterogeneous resources for solving large-scale problems in science, engineering, and commerce.
  • Globus Toolkit (GT):
    • the leading open source toolkit used today to build Grid environments.
introduction about gc with globus toolkit cont
Introduction about GC with Globus Toolkit (cont)
  • GT:
    • lets people share computing power, database, and other tools securely online across corporate, industrial, and geographic boundaries without sacrificing local autonomy.
    • includes software services and libraries for resource monitoring, discovery, and management, plus security, file management, data management, communication, and portability.
jade agents framework
JADE Agents framework
  • JADE (Java Agent DEvelopment frameworks):
    • is a framework fully implemented in Java language
    • simplifies the implementation of multi-agent systems through a middle-ware that complies with FIPA specifications and through a set of graphic tools that supports debugging and deployment phases.

Integrating JADE Agents into Globus based Grid environment
  • The necessity
  • The main difficulties
  • Related work
  • Our approach
the necessity
The necessity
  • Resources in Grid environment:
    • heterogeneous
    • geographically distributed
    • dynamically changed
  • Agent technologies’ abilities:
    • autonomy
    • co-operate
    • reaction
    • migration
the main difficulties
Globus Toolkit

To build a Grid Service: extends class GridServiceBase or use operation providers

A Grid Service lives in Globus Grid Service container

JADE framework

To build an Agent: extends class Agent and setup some behaviors

An Agent lives in JADE platform

The main difficulties

2 platforms use different standard formats of message

the main difficulties cont
The main difficulties (cont)
  • What is the solution that can ease the communication and interaction between objects living within these two separate environments?
related work
Related work
  • SoFAR project:
    • considers an Agent as a service by means of using Web service facilities to expose agent features
our approach hags
Our approach - HAGS
  • We consider a Grid Service as an Agent and add Agent’s behaviors into the service
  •  Hybrid Agent – Grid Service
  • Core idea: writing a Grid Service that extends the Agent class!!! Simple!!!
hags design and implementation
HAGS – Design and Implementation
  • Preparation
  • The HAGS
  • The Auto Setup Agent Grid Service
hags preparation
HAGS - Preparation
  • Copy six main libraries of JADE (jade.jar, iiop.jar, crimson.jar, http.jar Base64.jar, jadeTools.jar) into Globus Toolkit library directory ($GLOBUS_LOCATION/lib)
slide14
HAGS
  • Extends Agent class  Agent
  • Uses operation providers  Grid Service
  • Some important methods:
    • initialize(): create a non-main container and connect it to the default main container of JADE platform
    • setup() and takedown(): just setup code as for ordinary agents
    • preDestroy(): order the agent to delete itself
hags the auto setup agent grid service
HAGS - The Auto Setup Agent Grid Service
  • Automatically setup the whole JADE platform along with the grid service container
  • Can recognize when the grid service container is going to be shut down and automatically shut down the agent platform as well
  •  is successfully implemented

 ready-to-use

applications in hpcc hut grid
Applications in HPCC-HUT Grid
  • HPCC-HUT Grid
  • Application: Weka
  • The multi agent system as a grid information service
  • Agent as a resource manager
  • Agent as a resource broker
conclusion and future work
Conclusion and Future work
  • Results:
    • Idea and technical details of completing an HAGS system
    • Successful implementation in BKGrid 2005
  • Drawbacks:
    • The agent communication hasn’t been really controlled yet  security problems!!!
    • The overhead caused by the whole agent system to the grid environment
conclusion and future work cont
Conclusion and Future work (cont)
  • Future work:
    • Solve the drawbacks
    • Experiment the HAGS system in larger Grid environments
slide23

public void initialize(GridServiceBase base) throws GridServiceException {

this.base = base;

AgentContainer ac = null;

Runtime rt = Runtime.instance();

// Create a default profile

ProfileImpl p = new ProfileImpl(false);

try {

// Create a new non-main container, connecting to the

// default main container (i.e. on this host, port 1099)

ac = rt.createAgentContainer(p);

// Create a new agent

AgentController t2 = ac.acceptNewAgent("Broker "+System.currentTimeMillis(),this);

// fire-up the agent

t2.start();

} catch (Exception e2) {

e2.printStackTrace();

}
