G-Monitor: Grid Resource Broker Portal for Managing and Monitoring Application Execution on Global Grids
As Grids are emerging as the next-generation computing platform, the development of Web-based portals that hide low level details of accessing Grid services for deployment and execution management of applications is a fast evolving area. Whilst we have seen many web based portals developed for the grid environment, most interface the low-level grid middleware. These portals provide an easy to use interface they miss out on recent developments which have been made at the broker level. G-Monitor was developed to interface at the Grid Resource Broker (GRB) and provide the user with the ability to not only monitor, control, and steer execution of application jobs on Global Grids but to provide functionality such as Grid level resource discovery, grid economy, scheduling algorithms based on grid economy.
G-Monitor provides the user with a ubiquitous interface which can be used in any location to access any broker system the user desires. The user only needs access to a web browser and with it they are able to fully utilize the functionality provided by G-Monitor. As G-Monitor is a web-based portal the user does not have to worry about setting up SSH or exporting X displays, which can all be made more complicated depending on their firewall settings.
G-Monitor can interact with either the Gridbus or Nimrod G brokers GRB (Grid Resource Broker). These brokers use low-level services provided by low-level middleware such as Globus and Legion.
It provides a consistent interface that is easy to use, enabling the end-user to monitor, control, and steer execution of application jobs running within the Grid environment. With the use of a web browser the user is able to fully utilize the functionality of G-Monitor outlined in the Main feature section. See below:
- Retrieve and set QoS (quality of service) parameters, such as
- Deadline, Budget and Optimisation preferences, providing the user with access to scheduling algorithms that are constrained by specified budget or duration.
- Monitor/Control Jobs Information, such as
- Start, Stop, Grid node status and Execution time
- Monitor Resource status, such as
- Server name, Host name, Service cost and Status
- Monitor Experiment status, such as
- Deadline, Budget, Job status and Resource status
- Multi-User Interface
- User login and User preferences relating to available brokers and interface
- Real time graphs
- Graphs of the experiment progress are provided throughout experiment execution
- Start Experiment.
- Ability to upload experiment files using the G-Monitor interface and start experiments
- Grid Authentication.
- Ability to update Grid Authentication, without the need to access the Nimrod Broker
- Collect Experiment Files.
- Upon completion, experiment files with results can be collected
