The Open Science Grid, or OSG, is a worldwide network of computing power contributed by colleges, national labs, and other research-supporting institutions. Researchers at these types of institutions in the United States can access and use the OSG’s Open Science Pool, with capacity from more than 100 sites to drive scientific research. This tutorial will present an overview of OSG services, include hands-on exploration of OSG capabilities, and describe different pathways for engaging with the OSG as an organization.
