What was GridPP1?

• A team that built a working prototype grid of significant scale

> 2,000 (9,000) CPUs> 1,000 (5,000) TB of available storage> 1,000 (6,000) simultaneous jobs

• A complex project where 88% of the milestones were completed and all metrics were within specification

•253 Milestones, 112 Monitoring Metrics at present.•Must deliver a “Production Grid”: robust, reliable, resilient, secure, stable service delivered to end-user applications. •The Collaboration aims to develop, deploy and operate a very large Production Grid in the UK for use by the worldwide particle physics community.


LCG Overview

By 2007:- 100,000 CPUs- More than 100 institutes worldwide

- building on complex middleware being developed in advanced Grid technology projects, both in Europe (Glite) and in the USA (VDT)

- prototype went live in September 2003 in 12 countries

- Extensively tested by the LHC experiments during this summer


LHCb Data Challenge

424 CPU years (4,000 kSI2k months), 186M events • UK’s input significant (>1/4 total) • LCG(UK) resource:

– Tier-1 7.7%– Tier-2 sites:– London 3.9%– South 2.3%– North 1.4%

• DIRAC:– Imperial 2.0%– L'pool 3.1%– Oxford 0.1%– ScotGrid 5.1%

More Applications

ZEUS uses LCG•needs the Grid to respond to increasing demand for MC production• 5 million Geant events on Grid since August 2004

QCDGrid• For UKQCD • Currently a 4-site data grid • Key technologies used

- Globus Toolkit 2.4- European DataGrid- eXist XML database

•managing a few hundred gigabytes of data

Grid and e-Science Support

in 2008What areas require support?IV Running the Tier-1 Data CentreIV Hardware annual upgrade

IV Contribution to Tier-2 Sysman effort (non-PPARC) hardware IV Frontend Tier-2 hardware

IV Contribution to Tier-0 support

III One M/S/N expert in each of 6 areasIII Production manager and four Tier-2 coordinators

II Application/Grid experts (UK support)

I ATLAS Computing MoU commitments and supportI CMS Computing MoU commitments and supportI LHCb Core Tasks and Computing SupportI ALICE Computing supportI Future experiments adopt e-Infrastructure methods

• No GridPP management: (assume production mode established + devolved management to Institutes)

III. Grid Middleware

I. Experiment Layer

II. Application Middleware

IV. Facilities and Fabrics


OSC actions• Plan for support of physics analysis

community in 2007• Better understanding of capacity limits

at Tier1 and strategic priorities• £1M bid for LCG2 to go to PPARC

Science Committee• Plan to raise job completion efficiency• Statement on gLite• OSC views project as excellently

managed and very successful
