2 Summary Motivation and Context Projects and Grid Infrastructures At Work The Portuguese National Grid Initiative The Portuguese LCG Tier-2 deployment Future

3 F Motivation and Context

4 LIP and grid computing LIP participates in the ATLAS and CMS experiments The LHC data management and processing requires a novel computing approach: –Highly distributed community and resources both geographically and administrative wise –Integration of all computing and storage resources from the collaborating institutes –Common interface to access the resources –Transparent access to the resources –Single sign-on –e-Infrastructure … Grid computing was adopted to implement the LHC computing infrastructure Consequently LIP become involved in grid computing Now grid computing is also being used at LIP by non-LHC experiments

43 EGEE-III EGEE-III project approved and being signed by the partners –Expand the EGEE infrastructure More resources More users and communities –Prepare the migration towards a future European Infrastructure (EGI) based on the national grid initiatives (NGIs) Will start after EGEE-II (two years duration) Total budget 68.900.000 € –EU contribution 36.250.000 € –EU contribution for LIP 300.000 €

44 EGI Design Study proposal approved to the European Commission (started 1 st September’07) Supported by 31 National Grid Initiatives (NGIs) 2 year project to prepare the setup and operation of a new organizational model for a sustainable pan- European grid infrastructure Federated model bringing together NGIs to build a European organisation Well defined, complimentary responsibilities between NGIs and EGI EGI workshop held during EGEE’07 conference last week in Budapest Prof. Gaspar Barreira appointed spokesman of the advisory committee

45 Concerns Deployment and operation of the main node for grid computing –big challenge due to the dimension and characteristics –serving new communities –core services for national grid initiative and IBERGRID The LHC is starting –the LCG usage will increase and so the problems Need more human resources –user support and tier-2 operation –but attract people has been very difficult … Costs of infrastructure operation –electricity, maintenance etc… –these costs will increase a lot with the new deployments and upgrades
