Greg McChesney
Thesis Proposal Presentation
Computer Science, TTU

2. Overall Presentation Goal or Primary Purpose
Create a life-cycle for context management, and update Cataloger to implement the life-cycle.
Create a service to execute tasks
Greg McChesney
Beginning

3. Learning Objectives
As a result of this presentation, you will be able to:
Understand the purpose of contexts
Understand why a life-cycle is required
Utilize the life-cycle for your SORCER projects
Create a context in SORCER
Modify a context in SORCER
Launch a service in SORCER
View returned context from the service

4. Speaker’s Qualifications
Greg McChesney is a graduate student at TTU
Greg McChesney is planning to graduate in May of 2009 with a Master’s in Computer Science
Greg McChesney thesis is on Cataloger and creating contexts and jobs in SORCER

5. Did you know?
There is no method for creating dynamic Contexts, Tasks, or Jobs in the SORCER environment.

6. Presentation Agenda Background Knowledge What is a Context?
Discuss why a life-cycle is required
Overview of life-cycle
Discuss Task Editor
Feasibility Study
Demo
Schedule

7. Background Knowledge Many different Exertion-Oriented Systems
Implementation based on SORCER
Created by Mike Sobolewski in 2002
Based on JINI services
Framework constantly evolving
Interoperability with existing providers a concern for new development
Greg McChesney

8. All About Contexts A Context is a set of instructions for a provider.
The context various depending on the provider and the method being executed.
Contexts can specify anything about a provider
Example:
The context for makeDeposit in the AccountTester is: deposit/amount=amount

10. Need for a Life-Cycle No method to dynamically create Contexts
No method of updating or removing Contexts
Exertion-oriented programming cannot be dynamic without Context management
Updated Cataloger will provide more accessibility
Need Context methods for a task-editor
Greg McChesney

11. Proposed Life-Cycle Implement Context Methods into provider classes
New methods will be remotely invokeable
Get
Create
Update
Delete
Update Cataloger to utilize new methods
Greg McChesney

12. Life-Cycle Explained Context must be: Changes must be
Stored locally by provider
Reloaded on provider restart
Saved on update/create
Return blank when none is found
Changes must be
Compliant with existing providers
Provide backup file incase of bad context

13. Use Case Diagram Cataloger

16. Session #, Speaker Name
Need for a Task Editor
No common graphical method of creating tasks in SORCER
Each provider must have own GUI interface
Users must learn each providers interface
Provide easier development of new services
No method for creating Jobs
No method for saving and reusing Jobs.

17. Edit the Context?
Why would we want to edit the Context before we launch the Task?
The Context can often described input variables that are not static, editing it allows us to change them.
Example: The AccountTester would be useless if you could not specify how much you were depositing or withdrawing.
Greg McChesney

18. Output of the Task Tasks return a Context for their output
In the case of a simple Task the output is returned the user
In a Job the output is used as input for the next Task

19. Use Case-Task Manager

22. Feasibility Study Update Cataloger to test Life-Cycle methods
Get Context
Add Context
Update Context
Delete Context
Utilize provider from Air Force Research Center (Mealstrom) to validate task manager works as intended

24. Summary Benefits of Task Creation Panel
Session #, Speaker Name
Summary
Benefits of Task Creation Panel
Simplified user interface
Less work for new provider creators
In combination with new Cataloger will provide:
Complete Context Management
Task Initiation
Job Initiation
