Managing the execution environment for scientific workflows
Title: Managing the execution environment for scientific workflows
Short description: This talk will examine issues related to the execution of scientific workflows in distributed environments. It will describe the characteristics of some applications in astronomy, earthquake science, gravitational-wave physics, and others and their execution needs. It will show the different wide area execution environments, which need to support the workflow execution, with an emphasis on data storage options. The talk will then describe how the applications are mapped to these environments and executed by the Pegasus Workflow Management System and how the environment can be controlled to improve the execution of the workflow applications. Controlling the environment through resource provisioning will focus particularly on the provisioning of wide area networks that enable efficient data transfer to the application and within the workflow.
