Abstract: The Collaborative P-GRADE Portal supports the concurrent development and cooperative execution of workflow-based grid applications. In the development phase the collaborative users can contribute to the application with their own knowledge, files and resources. In the execution phase the workflow manager uses the collaborators’ delegated identities to access files and to execute jobs in the Grid. By applying different certificates during the different phases of the execution procedure, the workflow manager shares responsibility among the users. The paper introduces the issues related to the execution of concurrently developed grid applications and presents the mechanisms provided by the Collaborative P-GRADE Portal to deal with the issues either in single-grid or multi grid environments.
