17. Part 2 Grid Development Tools

18. Motivation • Grid Service Development in GT 3 / 4 (without an IDE) • Edit .java source Notepad / UltraEdit / vim / emacs • Compile javac classpath… • Generate WSDL java2wsdl / ant build.xml • Edit WSDD Notepad / UltraEdit / vim / emacs • Generate Gar file jar / ant build.xml • Deploy Copy • Service Client / Stub wsdl2java / ant • … • WSRF？ • Resource / ResourceHome / JNDIConfig / Stub / Flatten / Binding / …

19. Requirements • List of files required in a typical Globus project • service.wsdl • service-deploy.wsdd • jndi-config.xml • .java • security-descriptor • build.xml • …

20. Requirements • Automatically (skeleton) generation / GUI • Syntax Error Checking • Development Process Control • Write java code • Edit config files • Make gar • Deployment • Supporting OGSA / WSRF • Extensible

21. Related Works • GT3IDE (Globus 2005) • First release: May 2004 • BSD license • Still under development • GT3, Will support GT4 • http://gt3ide.sourceforge.net/ • Features • Automatic generation of WSDD and NS mappings • Partial generation of Java and WSDL • Java skeleton • Add a new remote method and the corresponding WSDL code is generated. • “Generate + Compile Stubs” and “Build GAR” buttons

22. CROWN Designer • Grid Development Environment • Eclipse Plug-in Based • Support GT4 (3.9.x) • Functions • Service Development • Service Deployment (Remotely & Dynamically) • System Monitor & Admin (Drag & Drop deploy)

23. CROWN Designer • Components • Wizards: Project / Service / Stub / Gar / … • Editors: WSDL / WSDD / JNDI / Keystore / WSPolicy / Security-Service-Config / XACML / … • Views: CROWN Topology • Actions: Deploy • GDEClasspath Container • Internal ant build file

25. CROWN Designer

26. Conclusion • Grid service development is a tough work • A development tools will • Reduce a lot of routine work • Easy to learn and master • Promote the development and deployment efficiency • Eclipse is good platform to develop an IDE (IDE lathe)

27. Future Works • Dev Tools • MDA Based Design & Implementation • WSDL / Java Code Synchronization • Exception Handling • Service (Remote) Debug • Workflow Modeling • Collaboration Support • Usability (Friendly UI / Documentation / Internationalization)

28. Part 3 Interactive Application for Grid

29. Motivation • Job Submission vs Interaction • Job Submission • No interference during job execution • All input to be ready at submission time • e.g. Gene Sequence Searching • Interaction • Multiple inputs required during job execution • Input/output dependency between steps (stages) • e.g. Chess Game, VR (Visual Surgical Operation)

30. Motivation • Collecting the requirement of Interactive Application • Design • Development • Deployment • Running • Investigate the WSRF / WS-Notification based design and implementation

31. Related Works • CFD Design & Visualization (GCC 2004) • Aero-crafts Aerodynamic Simulation and Optimization by Using “CFD-Grid” Based on Service Domain • Hong Liu, Xin-hua Lin, Yang Qi, Xin-da Lu, and Ming-lu Li • LNCS 3251, p. 745 ff.

33. WS-Notification Based Interaction • SOA • Stateless Service vs Stateful Resource • OGSA • OGSI • WS-Addressing • WSRF (WSRP / WSLT / WSSG / WSBF) • WS-Notification (WS-Topic)

34. WS-Notification Based Interaction • Basic Principle • Subscriber • Producer • Consumer • Topic • Space / Tree • Notification

35. WS-Notification Based Interaction • Publisher • Broker

36. Prototype - HalmaGame • Basic Roles of Halma

37. Prototype - HalmaGame • Main Problem • Game situation maintenance • Players / Board / LastStep / History / Winner • Get Notification when game situation changes • HalmaGame Rule Implementation • UI

38. createGame(“player1”) getGames() subscribe(tns:players) subscribe(tns:lastStep) joinGame subscribe(tns:lastStep) notify(tns:players) move notify(tns:lastStep) notify(tns:lastStep) move notify(tns:lastStep) notify(tns:lastStep) move Interaction Design Player1 Service Player2 Players=Player1 Players=Player1|Player2 lastStep=null lastStep=Step(…) … …

39. SWT based UI

40. Conclusion • Interaction is an important feature and problem of Grid application • WSRF / WS-Notification technologies can be apply to support interaction • UML Interaction Diagram is a good tools to modeling interactive processes
