论文摘要
交互式紧急计算是超级计算资源的小但不断增长的用户。但是，必须克服许多技术挑战，以使超级计算机完全适合于广泛的紧急工作负载，这可能会受益于此类工具所提供的计算能力。一个重要的问题是如何连接紧急工作量的不同组成部分；即用户，仿真代码和外部数据源以结构化且易于访问的方式一起。 在本文中，我们从编组和控制紧急工作负载的角度以及在单个HPC机器级别的角度探讨了工作流的作用。最终，通过使用太空天气预测紧急用例，我们需要两个工作流程系统，我们探讨了这两个工作流程系统所提供的好处，尤其是当一个工作流程利用它们互操作启用的灵活性时。
Interactive urgent computing is a small but growing user of supercomputing resources. However there are numerous technical challenges that must be overcome to make supercomputers fully suited to the wide range of urgent workloads which could benefit from the computational power delivered by such instruments. An important question is how to connect the different components of an urgent workload; namely the users, the simulation codes, and external data sources, together in a structured and accessible manner. In this paper we explore the role of workflows from both the perspective of marshalling and control of urgent workloads, and at the individual HPC machine level. Ultimately requiring two workflow systems, by using a space weather prediction urgent use-cases, we explore the benefit that these two workflow systems provide especially when one exploits the flexibility enabled by them interoperating.
