Project Initium: Remote Job Submission Design and Security Infrastructure Pawel Krepsztul MS Thesis Presentation A Thesis Presentation submitted to the Graduate Faculty of Fairfield University in partial fulfillment of the requirements for the degree of A Master of Science in the Electrical and Computer Engineering program

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

Outline Problem Approach Motivation Literature summary

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!

Approach Java Web Start SSL Web Server RMI/SSL implementation

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.

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

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

RJS Flow

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.

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