Pegasus is a widely used scientific workflow management system built on top of HTCondor DAGMan. This talk will highlight how Pegasus is deployed within the NSF ACCESS ecosystem and the NAIRR Pilot. We will cover access point deployments, including the hosted ACCESS Pegasus platform (Open OnDemand and Jupyter), workflow execution nodes in HPC environments, and a JupyterLab-based access point within the Purdue Anvil Composable Subsystem. On the execution side, we will discuss several provisioning strategies, including HTCondor Annex, custom virtual machines on the Jetstream2 cloud, simple glidein configurations for campus clusters, and a dynamically autoscaled TestPool environment designed for workflow development and testing.
