在本文中，我们描述了将现有的科学工作流技术集成到科学网关中的好处和挑战。科学的工作流管理器是处理大型计算任务的强大工具。领域科学家发现很难创建新的工作流，因此许多可以从工作流自动化中受益的任务经常被避免或手工执行。两种技术的结合为大众带来了工作流的好处。Pegasus工作流管理系统可以管理由数百万个任务组成的工作流，同时记录有关执行和中间结果的数据，以便最终结果的来源清晰。HUBzero科学合作平台为研究人员和教育工作者提供了一个构建和交付工具的场所。只需按下一个按钮，这些工具就可以在国家计算基础设施上启动Pegasus工作流，并将结果返回以进行绘图和可视化。因此，Pegasus和HUBzero的结合将为更广泛的受众带来高吞吐量计算。版权所有©2014 John Wiley & Sons， Ltd。
In this paper, we described the benefits and the challenges of integrating existing scientific workflow technologies into science gateways. Scientific workflow managers are powerful tools for handling large computational tasks. Domain scientists find it difficult to create new workflows, so many tasks that could benefit from workflow automation are often avoided or performed by hand. Two technologies have come together to bring the benefits of workflow to the masses. The Pegasus Workflow Management System can manage workflows comprised of millions of tasks, all the while recording data about the execution and intermediate results so that the provenance of the final result is clear. The HUBzero platform for scientific collaboration provides a venue for building and delivering tools to researchers and educators. With the press of a button, these tools can launch Pegasus workflows on national computing infrastructures and bring results back for plotting and visualization. As a result, the combination of Pegasus and HUBzero is bringing high‐throughput computing to a much wider audience. Copyright © 2014 John Wiley & Sons, Ltd.
