Description:

Accessing multiple HPC systems on-prem, remotely at partner institutions, and/or in the cloud for a single project is much more common now and opens up the ability for researchers to utilize those resources most suited to their work rather than those already readily accessible. However, the constraints on hardware, data storage resources, and software choices at each unique site and system can cause additional burdens to completing work efficiently. Federated computing seeks to alleviate these issues by creating more automated means by which to share credentials, handle data movement, track software dependencies and environments, and access unique hardware more easily independent of location by abstracting the machine and system specifics behind a user-defined resource requirement specification used to orchestrate the workflow desired. The overall goal is to simplify how HPC applications operate between on-premises, remote, and cloud systems as needed based on the requirements of the workflow to be executed. In this session, submissions will focus on efforts to develop, use, or improve workflows or management systems for federated use of on-prem, remote, and/or cloud HPC systems. Submissions are encouraged to highlight the many challenges involved with federated HPC systems and workflows, and the solutions proposed or employed to overcome them.
