This paper provides a blueprint for constructing collaborative and distributed knowledge discovery systems within Grid-based computing environments. The need for such systems is driven by the quest for sharing knowledge, information and computing resources within the boundaries of single large distributed organisations or within complex Virtual(More)
With the emergence of distributed resources and grid technologies there is a need to provide higher level in-formatics infrastructures allowing scientists to easily create and execute meaningful data integration and analysis processes that take advantage of the distributed nature of the available resources. These resources typically include heterogeneous(More)
Discovery Net is an application layer for providing grid-based knowledge discovery services. These services allow scientists to create and manage complex knowledge discovery workflows that integrate data and analysis routines provided as remote services. They also allow scientists to store, share and execute these workflows as well as publish them as new(More)
Common approaches to implementing Grid schedulers usually rely directly on relatively low-level protocols and services, to benefit from better performances by having full control of file and network usage patterns. Following this approach, the schedulers are bound to particular network protocols, communication patterns and persistence layers. With the(More)
