Open Science Grid (OSG)
https://www.opensciencegrid.org/

The Open Science Grid (OSG) advances science through open distributed computing. The OSG is a multi-disciplinary partnership to federate local, regional, community and national cyberinfrastructures to meet the needs of research and academic communities at all scales. The Open Science Grid (OSG) provides provide common service and support for resource providers and scientific institutions using a distributed fabric of high throughput computational services. The OSG does not own resources but provides software and services to users and resource providers alike to enable the opportunistic usage and sharing of resources. The OSG is jointly funded by the Department of Energy and the National Science Foundation. High-throughput computing needs of our scientific users are being met by a large number of computing resources that can be accessed directly through Globus services or more conveniently through grid technologies build on top of them. Storage resources provide easy access to terabytes of storage space through the common SRM protocol. The resources contributing to the OSG are primarily Linux clusters with Ethernet interconnects.
