4. The Open Science Grid The Open Science Grid’s mission is to help satisfy the ever-growing computing and data management requirements of researchers by enabling them to share a greater percentage of available computer cycles and software with less effort. The OSG is a distributed, common cyberinfrastructure spanning campus, regional, national and international boundaries. At over 50 provider sites, independently-owned and managed resources make up the distributed facility;  agreements between members provided the glue;  their requirements drive the evolution;  their effort helps make it happen. The facility is dedicated to high throughput computing and is open to researchers from all domains. OSG is a Cyberinfrastructure for Research The OSG is a framework for large scale distributed resource sharing, addressing the technology, policy and social requirements of sharing

6. What The OSG Offers Low-threshold access to many distributed computing and storage resources A combination of dedicated, scheduled, and opportunistic computing The Virtual Data Toolkit software packaging and distributions Grid Operations, including facility-wide monitoring, validation, information services and system integration testing Operational security Troubleshooting of end-to-end problems Education and Training

7. The OSG as a Community Alliance The OSG is a grass-roots endeavor bringing together research institutions throughout the U.S. and the World.  The OSG Consortium brings together the stakeholders.  The OSG Facility brings together resources and users. The OSG’s growing alliance of universities, national laboratories, scientific collaborations and software developers,  contribute to the OSG,  share ideas and technologies  reap the benefits of the integrated resources through both agreements with fellow members and opportunistic use. An active engagement effort adds new domains and resource providers to the OSG Consortium. Training is offered at semi-annual OSG Consortium meetings and through educational activities organized in collaboration with TeraGrid.  One to three day hands-on training sessions are offered around the U.S and abroad for users, administrators and developers.

9. Campus Grids They are a fundamental building block of the OSG  The multi-institutional, multi-disciplinary nature of the OSG is a macrocosm of many campus IT cyberinfrastructure coordination issues. Currently OSG has three operational campus grids on board:  Fermilab, Purdue, Wisconsin  Working to add Clemson, Harvard, Lehigh Elevation of jobs from Campus CI to OSG is transparent Campus scale brings value through  Richness of common software stack with common interfaces  Higher common denominator makes sharing easier  Greater collective buying power with venders  Synergy through common goals and achievements

10. Current OSG Resources OSG has more than 50 participating institutions, including self-operated research VOs, campus grids, regional grids and OSG-operated VOs Provides about 10,000 CPU-days per day in processing Provides 10 Terabytes per day in data transport CPU usage averages about 75% OSG is starting to offer support for MPI

11. Weekly OSG Process Hours

12. Facts and Figures from First Year of Operations OSG contributed an average of over one thousand CPU-days per day for two months to the D0 physics experiment OSG provided the LHC collaboration more than 30% of their processing cycles worldwide, in which up to 100 Terabytes per day were transferred across more than 7 storage sites LIGO has been running workflows of more than 10,000 jobs across more than 20 different OSG sites. A climate modeling application has accumulated more than 10,000 CPU days of processing on the OSG. The Kuhlman Lab completed structure predictions for ten proteins, consuming more than 10,000 CPU-days on the OSG.

13. Facing the CI Challenge Together OSG is looking for a few partners to help deploy campus wide grid infrastructure that integrates with local enterprise infrastructure and the national CI OSG’s Engagement Team is available to help scientists get their applications running on OSG  Low impact starting point  Help your researchers gain significant compute cycles while exploring OSG as a framework for your own campus CI osg@renci.org osg@renci.orgSend your inquires to osg@renci.orgosg@renci.org Learn more about the OSG at http:www.opensciencegrid.orgLearn more about the OSG at http:www.opensciencegrid.orghttp:www.opensciencegrid.org
