Exponential increases in data volumes and velocities are overwhelming finite human capabilities. Continued progress in science and engineering demands that we automate a broad spectrum of currently manual research data manipulation tasks, from transfer and sharing to acquisition, publication, indexing, analysis, and inference. To address these needs we are developing a fullfeatured distributed research automation platform, Globus Automate. Globus Automate is designed to increase productivity and research quality across many science disciplines by allowing scientists to offload the management of a broad range of data acquisition, manipulation, and analysis tasks to a cloud-hosted distributed research automation platform.
Globus Automate fills an important and previously un-met need in research cyberinfrastructure (CI). It addresses the problem of securely and reliably automating, for many thousands of scientists, sequences of data management tasks that may span locations, storage systems, administrative domains, and timescales, and integrate both mechanical and human inputs. This is a different problem to that of programming parallel workflows, as handled by HTCondor , Parsl , and Pegasus , or building integrated data management systems, as handled by iRODS , Rucio , and business rules engines . IFTTT is more similar, being simple, SaaS, and extensible to new events and actions, but it does not integrate with CI security or resources, or handle sequences of actions.
Our Automate implementation leverages Amazon Web Services. It uses Step Functions for flow automation, Simple Queue Service for event delivery, Reliable Database Service for persisting state, and Lambda for managing action executions. These mature, cloud- hosted services simplify delivery of a reliable, scalable service, allowing us to provide advanced capabilities to many scientists at modest cost. The Automate service enables the detection of events at Globus endpoints and other sources; the execution by the cloud-hosted Globus Automate engine of user-supplied automation flows either manually or as a result of data events; and the invocation of actions from those automation flows, including actions provided by Globus endpoints and services. The service is easily extensible by anyone via the definition of new events and actions to meet the needs of specific communities.
We have deployed Globus Automate to simplify and accelerate research for a diverse collection of scientific domains, from Materials Science to Cosmology, and scientific instruments, including light source synchrotrons and scanning electron microscopes. In this talk will present Globus Automate, its architecture and prototype implementation. We will frame this talk in the context of a real-world neurocartography use case in which Globus Automate is used to perform a complex image reconstruction and analysis pipeline using data obtained from Argonne National Laboratory's Advanced Light Source. This flow involves a complex, distributed, analysis and publication process to perform data-driven analyses of large unsectioned brain volumes, generated at > 20GB per minute, using HPC resources.
