工作流管理系统(WMS)通常由多个独立的软件组件组成或使用。这些组件的设计和开发通常来自利用相应WMS的科学应用的功能要求。因此,WMS设计反映了将来支持的应用程序中的核心功能要求。尽管大多数设计标准都被设计为尽可能通用,但对于某些新的工作流程应用程序,某些设计权衡可能是最佳的。我们认为,通过使用较大,更多样化的合成应用程序数据集,可以最大程度地减少从有限的实际应用程序中出现的WMS设计权衡。我们提出SDAG,这是一种用于生成合成良好的工作流(WFW)的工具,该工具跨越任何参考工作流程的合成WFW空间。这些合成的WFW使开发人员能够在广泛的工作流程上测试和评估WMS或其组成软件组件,并为WMS提供更多通用的设计标准。
Workflow management systems (WMS) are typically comprised of or make use of multiple independent software components. The design and development of those components is typically drawn from functional requirements of scientific applications that utilize the corresponding WMS. Consequently, the WMS design reflects those core functional requirements in applications that it supports in the future. Whereas most design criteria are engineered to be as generic as possible, some design trade-offs may prove sub-optimal for certain new workflow applications. We argue that WMS design tradeoffs that emerge from a limited set of real-world applications can be minimized by the use of larger, more varied synthetic application datasets. We present SDAG, a tool for generating synthetic well formed workflows (WFWs) that span a varied space of synthetic WFWs around any reference workflow. These synthetic WFWs enable developers to test and evaluate WMS or their constituent software components on a broad range of workflows and enable more generic design criteria for WMS.
