Description

We present a collection of tools and processes that facilitate onboarding a new science collaboration onto the OSG Fabric of Services. Such collaborations typically rely on computational workflows for simulations and analysis that are ideal for executing on OSG's distributed High Throughput Computing environment (dHTC). The produced output can be accumulated and aggregated at available ephemeral storage for inspection and then distribution to other facilities for long-term storage and further analysis. This work focuses on matching workflow requirements to tools and services that provide job management, automation (Pegasus WMS), and delivery of collaboration-specific software and input data to Execution Points (EP) using the Open Science Data Federation (OSDF) or Rucio. We describe best-supported practices to transfer data products to remote facilities at runtime or after the job completion. We emphasize the importance of early planning that meets the goals of the typically long life cycle of HEP experiments and advocate for an engagement model where the collaboration eventually becomes self-reliant in workload and data management.
