Tony Doyle - University of Glasgow UK Deployment Overview Significant resources within EDG. Currently being upgraded to EDG2. Integrating EDG on farms has been repeated many times but it is difficult. Sites are keen to take part within EDG2 currently, with LCG1 deployment after this. By the end of the year many HEP farms plan to be contributing to LCG1 resources. Basis of Deployment Input to LCG Plan. Input from Tier-1 (~50%) initially and four distributed Tier-2’s (50%) on ~Q timescale.

Tony Doyle - University of Glasgow RB Stress Tests (9/9/03): Benchmark for LCG Deployment Status (LCG report by Ian Bird): RB never crashed ran without problems at a load of 8.0 for several days in a row 20 streams with 100 jobs each ( typical error rate ~ 2 % still present ) RB stress test in a job storm of 50 streams, 20 jobs each : –50% of the streams ran out of connections between UI and RB. (configuration parameter – but machine constraints) –Remaining 50% streams finished normal ( 2% error rate) –Time between job-submit and return of the command (acceptance by the RB) is 3.5 seconds. ( independent of number of streams ) NOTE: RB interrogates all suitable CE's : wide area delay-killer

Tony Doyle - University of Glasgow Next m/w steps (9/9/03) Status (LCG report by Ian Bird): Next LCG-1 upgrades: The same software recompiled with gcc 3.2 New VDT? Based on Globus 2.4? LCG will work on this issue. Add VOMS Add RLI? – see discussion of RLS R-GMA now seems to be off the table *Corrective Action 16/9/03* Working group to resolve data access issues: –Components exist: SRM, GFAL, RLS, gridFTP; –need to make coherent based on use-cases and integrate with MSS’s For more features we would like to apply the simple rule: Add it if and only if –it is proven to work (by EDG, LCG, together) –it adds some desirable feature or feature requested by users –it makes the user’s application setup significantly simpler or practical –it is required by new user applications Bug fixing will always have the highest priority. Target release date for 2004 system: November

Tony Doyle - University of Glasgow RGMA – Status (16/9/03) Running on WP3, EDG-development and EDG-application testbeds Application Deployment: 29 CEs, 11 SEs, 10 sites in 6 countries –RGMA browser access in < 1sec Monitoring scripts being run on the testbeds and results linked from the WP3 web page – Registry replication is being tested on WP3 testbed –Better performance & higher reliability required Authentication successfully tested on WP3 testbed Two known bugs remain –Excessive threads requiring GOUT machine restart New code has been developed with extensive unit tests. Now being tested on WP3 testbed This new code will support at least 90 sites –Latest Producer choosing algorithm failing to reject bad LPs – shows up intermittent absence of information Revised algorithm needs coding (localised change)

Tony Doyle - University of Glasgow OptorSim: File Replication Simulation Test P2P file replication strategies: e.g. economic models 1. Optimisation principles applied to GridPP 2004 testbed with realistic PP use patterns/policies 2. Job scheduling: Queue access cost takes into account queue length and network connectivity. Anticipate replicas needed at “close” sites using three replication algorithms. 3. Build in realistic JANET background traffic 4. Replication algorithms optimise CPU use/job time as replicas are built up on the Grid.

Tony Doyle - University of Glasgow LCG Press Release… LHC Computing Grid goes Online CERN, Geneva, 29 September The world's particle physics community today announces the launch of the first phase of the LHC computing Grid (LCG-1). Designed to handle the unprecedented quantities of data that will be produced at CERN's Large Hadron Collider (LHC) from 2007 onwards, the LCG will provide a vital test-bed for new Grid computing technologies. These are set to revolutionise the way we use the world's computing resources in areas ranging from fundamental research to medical diagnosis. "The Grid enables us to harness the power of scientific computing centres wherever they may be to provide the most powerful computing resource the world has to offer" Les Robertson

Tony Doyle - University of GlasgowConclusions Visible progress this year in GridPP1 Management via the Project Map and Project Plan High level tasks and metrics: under control Major component is LCG –We contribute significantly to LCG and our success depends critically on LCG Middleware components on critical path w.r.t. LCG adoption Deployment – high and low level perspectives merge via monitoring/accounting Resource centre and experiment accounting are both important Today’s operations in the UK are built around a small team Future operations planning expands this team: Production Manager being appointed Middleware deployment focus on Information Service performance Security (deployment and policy) is emphasised “Production Grid” will be difficult to realise: need to start GridPP2 planning now (already underway) GridPP2 proposal: formal feedback in November Transition period for: –Middleware/Security/Networking Groups –Experiments Phase II –Production Grid Planning
