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

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
