A Definition and Analysis of the Role of Meta-workflows in Workflow Interoperability
IWSG '15 Proceedings of the 2015 7th International Workshop on Science Gateways(2015)
摘要
Scientific workflows orchestrate the execution of complex experiments on high performance computing platforms. Meta-workflows represent an emerging type of such workflows which aim to integrate multiple embedded workflows from potentially different workflow systems to achieve complex experimentation. Workflow interoperability plays a profound role in achieving this objective. This paper is focused at formalizing definitions of different types of workflows and meta-workflows to facilitate improved understanding and interoperability. It also includes thorough formalization of the coarse grained workflow interoperability approach highlighting the role of workflow systems. The paper presents a case study from Heliophysics which successfully demonstrates the use of technologies developed to realize the concepts of meta-workflows and workflow interoperability within a science gateway environment.
