Abstract

Globus Compute implements a hybrid Function as a Service (FaaS) model in which a single cloud-hosted service is used by users to manage execution of Python functions on user-owned and -managed Globus Compute endpoints deployed on arbitrary compute resources. Here we describe a new multi-user and multi-configuration Globus Compute endpoint. This system, which can be deployed by administrators in a privileged account, enables dynamic creation of user endpoints that are forked as new processes in user space. The multi-user endpoint is designed to provide the security interfaces necessary for deployment on large, shared HPC clusters by, for example, restricting user endpoint configurations, enforcing various authorization policies, and via customizable identity-username mapping.
