OSG’s distributed facility, composed of laboratory, campus and community resources, is designed to meet the current and future needs of scientific Virtual Organizations (VOs) at all scales. It provides a broad range of common services and support, a software platform, and a set of operational principles that organizes and supports users and resources in Virtual Organizations. OSG is jointly funded, until 2011, by the Department of Energy and the National Science Foundation. 
Figure : Sites in the OSG Facility OSG does not own any computing or storage resources. Rather, these are contributed by the members of the OSG Consortium and used both by the owning VO and other VOs. OSG resources are summarized in Error: Reference source not found. Table : OSG computing resources
The overall usage of OSG continues to grow though utilization by each stakeholder varies depending on its needs during any particular interval. Overall use of the facility in 2009 was approximately 240M hours, a 70% increase from the previous year! (Detailed usage plots can be found in the attached document.) During stable normal operations, OSG provides approximately 700,000 CPU wall clock hours a day (~30,000 cpu days a day) with peaks occasionally exceeding 900,000 CPU wall clock hours a day; approximately 100,000 to 200,000 opportunistic wall clock hours are available on a daily basis for resource sharing. The efficiency of use is based on the ratio of CPU to I/O in the applications as well as existing demand. Based on our transfer accounting (which is in its early days and ongoing in depth validation), we see over 300TB of data movement (both intra- and inter-site) on a daily basis with peaks of 600TB/day; of this, we estimate 25% is GridFTP based transfers and the rest is via LAN-optimized protocols.
