Shared Common Distributed Infrastructure Supporting access to contributed Processing, disk & tape resources Over production and research networks and Open tor use by Science Collaborations
Snapshot of Jobs on OSGs
96 Resources across
production & integration infrastructures
Using production & research networks
Sustaining through OSG submissions:
3,000-4,000 simultaneous jobs .
Peak test jobs of 15K a day.
20 Virtual Organizations +6 operations
Includes 25% non-physics.
~20,000 CPUs (from 30 to 4000)
~6 PB Tapes
~4 PB Shared Disk
2009OSG - a Community Consortium
Inter-Operating and Co-Operating Grids: Campus, Regional, Community, National, International.
Virtual Organizations doing Research & Education.
Each activity includes technical work with Collaborators in the US and elsewhere.
User Science Codes and Interfaces
Portals, databases etc
Data and workflow management etc
Data replication etc
OSG Release Cache:
OSG specific configurations, utilities etc.
Virtual Data Toolkit (VDT) core technologies + software needed by stakeholders:many components shared with EGEE
Core grid technology distributions:
Condor, Globus, Myproxy: shared with TeraGrid and others
Existing Operating, Batch systems and Utilities.
PB/mo = < 3 Gb/s>
High impact path
University of Science and Technology of China
Data Rates need to reach ~X3 in 1 year
~7 Tier-1s, CERN + Tier-2s
Bejing is a Tier-2 in this set
Handful of submission points.
+ test jobs at 55K/day.
