Implementation

Technologies Apache Web Server (CGI) Perl JavaScript Nimrod-G Protocol

Issues Timezones issue, as webclient, webserver and

nimrod server can all be in different Timezones! (Fix:UTC)

Scalability - Handles large scale experiments (1000’s of Jobs,100’s of Resources.)

Conclusion

G-Monitor Web based implementation

provides easy to use and ubiquitous interace to the Grid.

Easy to setup. Scalable and places low overhead on the network Try it and Download from http://www.gridbus.org/

Future Work Integrate G-monitor into a HTML framework (Eg.

WebGUI) Integrate further job/experiment statistics. Integrate further job/experiment control.
