【 摘 要 】

Motivation: In the last years various distributed computing infrastructures (DCIs) have been developed to support national and international research activities. Today several applications from diverse domains have been ported to them. For example, workflow- based grid applications for medical imaging have been developed in the Netherlands within the VL-e project, in France within the EGI biomed VO and in Germany within the German medical D-Grid projects. These applications are based on the resources and workflow systems provided by respective grid infrastructures, and researchers now face difficulties to exchange applications and data across the DCIs. This would be important to obtain access to additional resources and to enable sharing of applications and methodology. Unfortunately today the mobility across DCIs at application level is hardly supported. Results: The European project SHIWA - Sharing Interoperable Workflows for large-scale scientific simulations on Available DCIs1 aims to realize interoperability at workflow level. This will allow domain researchers to share and reuse their scientific workflows across DCIs. Different use cases are identified which result in a two-fold approach: coarse-grained and fine-grained workflow interoperability. First results are presented for two pilot applications - neuroimaging and chemistryand two workflow systems - MOTEUR and GWES. We analyze the similarities and differences between these systems, and show implementation strategies for easily combine and translate scientific workflows. These results enable sharing and reusing workflows and grid services between EGI, D-Grid, and Dutch Grid infrastructures Availability: The workflow managers GWES and MOTEUR are both open source and free for academic use. The mentioned workflows will be published within the SHIWA platform.
