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

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

Definitions

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

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.
