Efficient and robust system for accessing computational resources and managing job operations is a key component of any Grid framework designed to support large distributed computing environment. Computing Resource Execution and Management (CREAM) is a simple, minimal system designed to provide efficient processing of a large number of requests for(More)
In the first phase of the European DataGrid project, the 'workload management' package (WP1) implemented a working prototype, providing users with an environment allowing to define and submit jobs to the Grid, and able to find and use the " best " resources for these jobs. Application users have now been experiencing for about a year with this first release(More)
Application users have now been experiencing for about a year with the standardized resource brokering services provided by the 'workload management' package of the EU DataGrid project (WP1). Understanding, shaping and pushing the limits of the system has provided valuable feedback on both its design and implementation. A digest of the lessons, and " better(More)
Contemporary Grids are characterized by a middleware that provides the necessary virtualization of computation and data resources for the shared working environment of the Grid. In a large-scale view, different middleware technologies and implementations have to coexist. The SOA approach provides the needed architectural backbone for interoperable(More)
The Grid is currently living an exciting evolution step to turn from a niche technological infrastructure to a widely used Business environment. To this aim, Workflows are playing an important role acting as the link towards the well-established Business Process Management environment. A number of Grid projects worldwide are trying to implement this link(More)
Execution of interactive applications on a Grid environment is a challenging problem that requires the cooperation of several middleware tools and services. In this chapter, we present the experience carried out in the CrossGrid project to provide transparent and reliable support for such types of application. Our solution is based on the notion of split(More)
