Usage of the Open Science Grid

  • Brian Bockelman
Conference paper


Over the last year, the Open Science Grid usage has seen a substantial increase in CPU usage; from June 2008 to January 2009, the usage went from approximately 6 million wall hours to 14 million wall hours. This increase has come from ramp-up of the WLCG experiments and increased interest from FNAL Run-II experiments. We present the current usage patterns and analyze how increased HEP usage has affected non-HEP usage of the grid. We present various means of measuring the “size” of the Open Science Grid and determining the grid-accessible portion of clusters, and discuss difficulties of performing quantitative measurements in a distributed collaborative environment. Finally, we look forward to future challenges presented by continued growth of the grid, especially with regards to upcoming LHC collisions.
