In this paper we propose to achieve a semantic equivalence between a visual- and a script-based workflow development paradigm. We accomplish this by building a script language which execution semantics matches an existing sophisticated, data-parallel scientific workflow language and its underlying GUI-based core workflow enactor. This...

Resource-intensive and complex medical imaging ap- plications can benefit from the use of scientific workflow technology for their design, rapid implementation and reuse, but at the same time they require a Grid comput- ing infrastructure to execute efficiently. In this paper we describe a technical architecture that bridges the gap between the...

Different scientific workflow languages have been developed to help programmers in designing complex data analysis pro- cedures. However, little effort has been invested in com- paring and finding a common root for existing approaches. This work is motivated by the search for a scientific workflow language which coherently integrates different...

Porting applications to Distributed Computing Infrastruc- tures (DCIs) is eased by the use of workflow abstractions. Yet, estimating the impact of the execution DCI on applica- tion performance is difficult due to the heterogeneity of the resources available, middleware and operation models. This paper describes a workflow-based experimental...

Production exploitation of cardiac image analysis tools is hampered by the lack of proper IT infrastructure in health institutions, the non trivial integration of heterogeneous codes in coherent analysis procedures, and the need to achieve complete automation of these methods. HealthGrids are promising technologies to address these...
