13. SNIC 2006, - 13 SweGrid Observations Global user identity –AA services that scale must be implemented –All centers must agree on a common lowest level of security. This will affect general security policy for HPC centers. Unified support organization –All helpdesk activities and other support needs to be coordinated between centers. Users can not decide where their jobs will be run (should not) and expect the same level of service at all sites. More bandwidth is needed –To be able to move data between the nodes in SweGrid before and after execution of jobs continuously increasing bandwidth will be needed More storage is needed –Users can despite increasing bandwidth not fetch all data back home. Storage for both temporary and permanent data will be needed in close proximity to processor capacity

14. SNIC 2006, - 14 SweGrid status All nodes installed during January 2004 Extensive use of the resources already –Local batch queues –GRID queues through the NorduGrid middlware - ARC –60 users 1/3 of SweGrid is dedicated to HEP (200 CPUs) Contributed to Atlas Data Challenge 2 –As a partner in NorduGrid Consistenlty large contributor to LCG –Compatibility between ARC and gLite Forms the core of the Northern EGEE ROC Accounting is now in place

15. SNIC 2006, - 15 SweGrid II New Proposal Under Development 10x capacity –CPU –Storage –Technical specification being developed a Point 2 Point connections Application will be submitted in January Installation during 2007 Application specific portals Improved user support Interface to international projects –NDGF/NorduGrid –EGEE Special agreements for “large users”

16. SNIC 2006, - 16 The NorduGrid project Started in January 2001 & funded by NorduNet-2 –Initial goal: to deploy DataGrid middleware to run “ATLAS Data Challenge” NorduGrid essentials –Built on GT –Replaces some Globus core services and introduces some new services –Grid-manager, Gridftp, User interface & Broker, information model, Monitoring –Middleware named ARC Track record –Contributed 30% of the total resources to ATLAS DC II –Enabling Nordic participation in LCG Service Challenges Continuation –Provides middleware for the Nordic Data Grid Facility –Co-operation and interoperability with EGEE/LCG

17. SNIC 2006, - 17 Resources running ARC Currently available resources: –10 countries, 40+ sites, ~4000 CPUs, ~30 TB storage –4 dedicated test clusters (3-4 CPUs) –SweGrid –Few university production-class facilities (20 to 60 CPUs) –Three world-class clusters in Sweden and Denmark, listed in Top500 Other resources come and go –Canada, Japan – test set-ups –CERN, Russia – clients –Australia –Estonia –Anybody can join or part People: –the “core” team grew to 7 persons –local sys admins are called up when users need an upgrade
