9. The NorduGrid project • Initiated by several Nordic universities • Copenhagen, Lund, Stockholm, Oslo, Bergen, Helsinki, later: Linköping and Umeå • Started in January 2001 & funded by NorduNet-2 • Simultaneously with EU DataGrid, but with only a 2 years budget and 3 new positions • Initial goal: to deploy DataGrid middleware to run “ATLAS Data Challenge” • Cooperation with DataGrid • Common Certification Authority and Virtual Organization tools, Globus2 configuration • Common applications (high-energy physics research) • Switched from deployment to R&D in February 2002 • Deployed a light-weight and yet reliable and robust Grid solution in time for the ATLAS DC tests in May 2002 • Continuation • NorduGrid was one of the driving forces behind the creation of the ”North European Grid Federation” together with the Dutch Grid, Belgium and Estonia • Is an option for middleware for the ”Nordic Data Grid Facility” • …as well as for the Swedish Grid facility SWEGRID Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 9

10. The resources • Currently available resources: • 4 dedicated test clusters (3-4 CPUs) • Some junkyard-class second-hand clusters (4 to 80 CPUs) • Few university production-class facilities (20 to 60 CPUs) • Two world-class clusters in Sweden, listed in Top500 (230 and 440 CPUs) • Other resources come and go • Canada, Japan – test set-ups • CERN, Russia – clients • It’s open, anybody can join or part • People: • the “core” team grew to 7 persons • local sysadmins are only called up when users need an upgrade Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 10

12. Reflections on NorduGrid • Bottom up project driven by an application motivated group of talented people • Middleware adaptation and development has followed a flexible and minimally invasive approach • HPC centers are currently “connecting” large resources since it is good PR for the centers • As soon as NorduGrid usage of these resources increases they will be disconnected. There is no such thing as free cycles! • Motivation of resource allocations is missing • NorduGrid lacks an approved procedure for resource allocation to VOs and individual user groups based on scientific reviews of proposals • Funding for the continuation of the project is today unclear • NorduGrid may remain a middleware project that delivers solutions to other Nordic production Grids such as SweGrid Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 12

13. Nordic DataGrid Facility • Based on a Working paper by the NOS-N working group (April 4, 2002): road map towards the Nordic Grid Facility • Project started 2003-01-01 • Builds on interest from • Biomedical sciences • Earth sicences • Space and astro sciences • High energy physics • Gradual build-up • Project leader and 4 postdocs • Projects in middleware and application interfaces Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 13

17. Nordic Grid Consortium • PDC, CSC and Parallab have signed Memorandum of Understanding. • The Vision is to: • “create a Grid for the benefit of the users of the facilities” • Purpose is to: • Explore Grid production from an HPC-center point of view • Explore means of exchanging resource allocations across national borders • NGC is an inclusive organisation and will expand to include all major HPC centers in Scandinavia Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 17

18. Conclusions • A large number of GRID initiatives in the Nordic Region • HPC – centers and GRID initatives are rapidly merging • Strong need for a mechanism for exchange of resources over the borders • Very few existing users belong to VOs • Most cycles at HPC-centers are used for chemistry • How will these users become GRID users? • There is a need for authorities that grant resources to projects (VOs) • Locally • Regionally • Nationally • Internationally Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 18

19. North European Grid • NEG is an EGEE federation consisting of • Belgium, Denmark, Estonia, Finland, Holland, Norway, Sweden • NEG is responsible for the security in EGEE • NEG is hosting an EGEE Regional Operations Center • Two lead sites • SARA • SNIC/PDC • NEG executive committee has been formed • One representative per partner in the federation plus also a national representative per country • Phone meetings every second Friday to deal with common issues • NEG will play an important role in the coordination of Grid efforts in the federation Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 19

20. The NorduGrid philosophy • No single point of failure • Resource owners have full control of the contributed resources • Installation details should not be dictated • Method, OS version, configuration, etc. • As little restriction on site configuration as possible • Computing nodes should not be required to be on the public network • Clusters need not be dedicated • NorduGrid software should be able to use existing system and Globus installation • Patched Globus RPMs are provided • Start with something simple that works and proceed from there Workshop on eInfrastructure (Internet and Grids) Rome Dec-03 - 21
