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)
Semantic grid is becoming a key enabler for next generation grid and the need of supporting process description and enactment, by means of composition of multiple resources, emerged as one of the fundamental requirements. Within NextGRID project, the idea of adopting business processes (expressed as workflow policies) as architectural components in a next(More)

The workload management task of the DataGrid project was mandated to define and implement a suitable architecture for distributed scheduling and resource management in a Grid environment. The result was the design and implementation of a Grid Workload Management System, a super-scheduler with the distinguishing property of being able to take data access(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)
Workflows have an increasing role in scientific applications programming and business environment development because they are an effective technology to define composition of different pieces of knowledge, both in the application domain and in the business context. However, workflows are addressed in a number of different perspectives and no consensus has(More)
Society and business are demanding systems that can securely and costeffectively exploit opportunities presented by an Internet of Services. To achieve this goal a system must dynamically adapt to its environment and consider multiple and shifting stakeholder concerns such as application functionality, policies and business processes. In this paper we(More)
This document concerns with the implementation of the P3L parallel programming language on the MPI abstract Machine. First we focus our attention on the characteristics of the MPI Abstract Machine, then we present a preliminary implementaton for each P3L construct based on that architecture.
