1 Tony Doyle - University of Glasgow 30 November 2005ScotGrid Phase 2 Procurement ScotGrid Procurement … a future news item 25 June 2006: ScotGrid's 4th birthday June 25th marks the fourth anniversary of ScotGrid deployment. After four years, the system has provided more than 2 million CPU hours and 200,000 completed jobs. The system is fully integrated with the LCG Grid, the basic Grid system for the EU Enabling Grids for E-Science in Europe (EGEE) project, and the Grid for UK Particle Physics (GridPP) testbed as part of the National Grid Service. Locally, the user service supports 12 Groups (ATLAS, BaBar, Bioinformatics, CDF, Device Modelling, Grid Data Management, Information Retrieval, LHCb, Medipix, MICE, UKQCD and ZEUS) with approximately 100 individual users. Many external Grid Virtual Organisations are also being supported. The hardware is currently being upgraded and will be available for users in Q3 2006….

2 Tony Doyle - University of Glasgow 30 November 2005ScotGrid Phase 2 Procurement Grid Overview Aim: by 2008 (full years data taking) -CPU ~100MSi2k (100,000 CPUs) -Storage ~80PB - Involving >100 institutes worldwide -Build on complex middleware being developed in advanced Grid technology projects, both in Europe (Glite) and in the USA (VDT) 1.Prototype went live in September 2003 in 12 countries 2.Extensively tested by the LHC experiments in September sites, 13,797 CPUs, 5PB storage in September 2005

3 Tony Doyle - University of Glasgow 30 November 2005ScotGrid Phase 2 Procurement 1.Large UK-wide Project (20 Institutes, £33m over six years [Sep Aug 07]) 2.A team that built a working prototype Grid of significant scale UK (worldwide) > 2,000 (10,000) CPUs > 1,000 (5,000) TB of storage > 1,000 (6,000) simultaneous jobs 3.A complex project where 88% of the milestones were completed in the first phase What is GridPP?

4 Tony Doyle - University of Glasgow 30 November 2005ScotGrid Phase 2 Procurement 1.Glasgow/Edinburgh/Durham/ (Dundee) Project 2.Compute-intensive jobs performed at Glasgow and Durham 3.Data-intensive jobs performed at Edinburgh 4.First applications using the Grid. Meeting real requirements of Grid applications: currently Particle Physics, Bioinformatics, Computing Science, Electrical Engineering 5.Glasgow leading R&D in Grid Data Management and Security 6.Edinburgh leading co-ordination and R&D in Networking and Storage 7.Management part of a worldwide Grid infrastructure through GridPP and EGEE What is?

5 Tony Doyle - University of Glasgow 30 November 2005ScotGrid Phase 2 Procurement What are the Grid challenges? Data Management, Security and Sharing 1. Software process 2. Software efficiency 3. Deployment planning 4. Link centres 5. Share data 6. Manage data7. Install software 8. Analyse data9. Accounting 10. Policies
