Abstract
The gLite Workload Management System represents a key entry point to high-end services available on a Grid. Being designed as part of the European Grid within the six years long EU-funded EGEE project, the WMS is meant to provide reliable and efficient distribution and management of end-user requests. The WMS basically translates user requirements and preferences into specific operations and decisions—dictated by the general status of all other Grid services—while taking responsibility to bring requests to successful completion. The WMS implements an “early binding” approach to meta-scheduling as a neat Grid-aware solution, able to optimise resource access and to satisfy requests for computation together with data. Several added value features are provided for job submission, different job types are supported from simple batch to a variety of compounds, all described in this paper. Conceived to be a scalable service, the WMS has been deployed in different physical layouts according to specific needs for performance, thanks to the modularity of its design. In this paper we show what has been achieved to provide adequate workload and management components, suitable to be deployed in a production-quality Grid while covering the design and development of the gLite WMS.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
