    Abstract:
    Computational science today depends on many complex, data-intensive applications operating on distributed datasets that originate from a variety of scientific instruments and data repositories. Moreover, modern cyberinfrastructure has a highly distributed and heterogeneous character, with compute sites in multiple locations offering access to both commodity hardware and accelerators, but they are not close to the data.
    Workflow management systems and scientific workflows are great tools in leveraging the infrastructure given to them and making data available to where a computation will take place. They automate science, making it portable and reproducible. However, until now, even though workflow management systems are aware of the infrastructure they don't control elements of it. Software defined federated cyberinfrastructure has paved the way for workflow management systems to control how the cyberinfrastructure is configured allowing for data access and network optimisations based on the needs of a science application.
    In this work we explore approaches and techniques to programmatically configure and control the cyberinfrastructure based on the requirements of an application and we provide solutions in efficiently sharing the allocated network resources among workflow ensembles.
