Workshop on eInfrastructure (Internet and Grids) Rome Dec 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 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 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 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 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 Nordic DataGrid Facility Prototype period : Scope 0.54 MEuro. Capacity building : Scope 15 MEuro.

Workshop on eInfrastructure (Internet and Grids) Rome Dec 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 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 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 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
