1. Project Initium: Remote Job Submission Pawel Krepsztul Fairfield University Electrical and Computer Engineering program

2. The goal of the research Heterogeneous computing Screen Saver Integrated Security Java Solution Operating system Independent Ability to submit jobs to the Grid

3. Outline Problem Approach Motivation Literature summary Validation Summary

4. Problem Use CPU cycles of idle computers Idle 118 hours out of every 168 hours during the week (i.e., 70% of the time). This is a BIG WASTE!

5. Approach Java Web Start SSL Web Server RMI/SSL implementation

6. Motivation Workstations are idle 14 or more hours per workday. Waste of CPU cycles, storage capacity, and network bandwidth. Security issues in grid computing Programs are safe to run on grid computers.

7. Literature Summary Investigate eight different grid systems. Six java based and two C/.Net solutions Five used Globus Toolkit for security Two systems not secured None grid use Java Web Start Technology

8. Definitions Web Server (WS) – jobs and answers holder Look up Server (LUS) - jobs and answers dispatcher Computation Server (CS) – job executor

9. Lus Panel

10. Control Panel

11. RJS Flow

12. Validation RJS system was benchmarked computing one Mandelbrot task subdivided into eight jobs. After each test experiment, the system created eight answers jars. Several experiments were run using one to six computation servers.

13. Execution Time versus number of participating CS’s.

14. Visual output from the all eight jobs

15. Mandelbrot set

16. Conclusion Three major contributions and advantages of RJS: 1)Deployment 2)Portability 3)Security
