摘要
Distributed scientific and engineering computations on service-oriented architectures are often represented as data-driven workflows. Workflows are a convenient abstraction that allows users to compose applications in a visual programming environment, and execute them by means of a workflow execution engine. For a large class of scientific applications web-based portals can provide a user-friendly problem-solving environment that hides the complexities of executing workflow applications in a distributed environment. However, the creation and configuration of an application portal requires considerable expertise in portal technologies, which scientific end-users generally do not have. To address this problem this paper presents tools for automatically converting a workflow into a fully configured portal which can then be used to execute the workflow.
