Personalised Grid service discovery

We take a broad view that ultimately Gridor Web-services must be located via personalised, semantic-rich discovery processes. We argue that such processes must rely on the storage of arbitrary metadata about services that originates from both service providers and service users. Examples of such metadata are reliability metrics, quality of service data, or semantic service description markup. T...

Performance evaluation of a grid resource monitoring and discovery service

The Grid Information Service (GIS) is one of the Grid Common Services which make up the basic functions belonging to Grids. This service offers a resource discovery mechanism, of which an implementation is provided by the Monitoring and Discovery Service (MDS-2), which is part of the Globus Toolkitw. Grid applications are typically the users of this resource discovery mechanism; knowledge is th...

Optimal restart times for moments of completion time - Software, IEE Proceedings- [see also Software Engineering, IEE Proceedings]

Restart is an application-level technique that speeds up jobs with highly variable completion times. The authors present an efficient iterative algorithm to determine the restart strategy that minimises higher moments of completion time, when the total number of restarts is finite. They demonstrate its computational efficiency in comparison with alternative algorithms. They also discuss fast ap...

Stochastic analysis of scheduling strategies in a grid-based resource model - Software, IEE Proceedings- [see also Software Engineering, IEE Proceedings]

A model inspired by a scenario found in Grid-based scheduling systems is considered. Scheduling is performed remotely without access to up-to-date resource availability and usage information. This system is modelled as a collection of queues where servers break down and are subsequently repaired. There is a delay before the scheduler learns of failures, and requests may continue to arrive into ...
