Introduction

• Functionality/Requirements
• Experiment Management and Control
• Job control
• Broker QoS
• Experiment status
• Job status

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!
  (FixUTC)
• Scalability - Handles large scale experiments
  (1000s of Jobs,100s 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.
