GridPP3 project status Sarah Pearce 24 April 2010 GridPP25 Ambleside

2 GridPP24, Ambleside Skiddaw The 4 th highest mountain in England (or the 3 rd, depending) The “simplest of the mountains of this height to ascend” A well trodden tourist track The first summit of the ‘Bob Graham Round’ fell running challenge The view from the top is ‘panoramic’ 24/8/10

3 GridPP24, Ambleside Since the last meeting LHC continues to take data – see Pete’s talk EGEE finished and EGI started – see Jeremy and Andy’s discussion Tier-1 running well Tier-2s procuring more equipment from the 2 nd round of hardware grants GridPP4 proposal reviewed and accepted – see Dave’s talk 24/8/10

4 GridPP24, Ambleside Tier-1 CPU hardware delivered and commissioned in time to meet WLCG pledge One tranche of disk delivery still going through acceptance Procurements for next round of CPU and disk have started Testing for upgrade to CASTOR (from 2.1.7) Operations very stable 24/8/10

5 GridPP24, Ambleside Tier-2s RHUL cluster successfully running in new RHUL machine room UCL-Central removed from list of UK sites All grants for 2 nd tranche of hardware issued: sites procuring hardware to meet 2010 pledge. Several sites made significant upgrades, including: –Sheffield (inc. air con/ temperature monitoring equipment) –Lancaster kit for new machine room –Cambridge increased disk and CPU –IC moved site outside firewall – x2 improvement in performance Some issues with staffing (Durham, likely at Bristol) –Discussion today at PMB/ DB on how to cover sites with small amounts (or no) dedicated staff 24/8/10

6 GridPP24, Ambleside EGI, EGI-Inspire etc. EGI started operations on 1 May 2010 –Governed by EGI Council –Executive Board reports to Council – Neil Geddes elected member of the EB –Key staff now in Amsterdam (except Neasan) –First Technical Forum will Sept in Amsterdam EGI-InSPIRE also started –Grant Agreement with EC not signed yet – so no money so far e-ScienceTalk will start 1 September –funds UK staff at IC and QMUL 24/4/10

12 GridPP24, Ambleside Project map - statistics MetricsMilestones 24/8/10

13 GridPP24, Ambleside Experiments ATLAS T1 data acceptance from CERN, T1s and T2s up from 79% to 96% Data availability in T2 storage is green, but this hides quite significant SE issues at some sites LHCb Sharp drop in the proportion of production computing taking place in the UK, from 28% to 16% - early user jobs at CERN Issue with data transfer from the T2s to RAL (1.2.5) Ganga milestone delayed (Integrate XML job summary from Dirac into Ganga) due to setting up new DAST CMS Some data loss at T1 and T2 but not considered significant by CMS Going well – CMS recognises the UK’s contribution Other experiments MINOS, D0 and Babar mainly this quarter Red milestones for experiment satisfaction/user support questionnaire – waiting on ATLAS reply 24/8/10

14 GridPP24, Ambleside Grid services Operations Fraction job slots used (Target 80%, achieved 37%). Overall occupancy low this quarter. Security No incidents this quarter Networking No red metrics. Second (resilient) OPN link from RAL is operational Data and storage Record FTS transfer rates (2.4.4), with an average over 370 MB/s sustained over the whole quarter Still questions over published storage values 24/8/10

15 GridPP24, Ambleside Tier-1 T1 operating extremely well. Nearly all metrics for front-end systems at 100%. CASTOR SAM tests at 100% for the first time (3.4.8) Red metrics for farm occupancy (43%, against a target of 80%, ) Red milestone for 2009 disk hardware accepted. One tranche of disk capacity failed acceptance – firmware fix and running again. Red milestone on moving out of Atlas centre – revised and will be met next quarter 24/8/10

16 GridPP24, Ambleside Tier-2s % of promised CPU available – green for all Tier-2s (metric 2). % of disk red for NorthGrid, but procurements underway. Next quarter will be measured against 2010 pledge. SAM availability and reliability tests green or orange (so above 90%) for most Tier-2s (metrics 3&4). Range of issues at SouthGrid sites. Other red metrics: CPU utilisation (wall clock time & CPU time, metrics 7/8) LondonGrid, SouthGrid – but generally low Number of management meetings NorthGrid (metric 11) Staff changes at several sites (Durham, Glasgow, Manchester, QMUL) 24/8/10

17 GridPP24, Ambleside Management and external Project execution – red metrics All quarterly reports in by target time (though some earlier than others…) Red metric for no. of UB meetings Rest of Map No red metrics EGEE/EGI metrics being revised to reflect EGI start 24/8/10

18 GridPP24, Ambleside Risk register 24/8/10 3 high level risks –Recruitment and retention – more of an issue as we get closer to GridPP4 –Sudden loss of key staff – as above –Uncertain long term funding. GridPP4 approved, but government funding an issue everywhere

19 GridPP24, Ambleside Finances - summary 24/8/10

20 GridPP24, Ambleside Finances Substantial reduction in the Tier-1 FY10 hardware line –STFC requested reduced capital spend of £1.1m –New experiment resource requirements from C-RRB in April Overall (to 2015) reduction in disk and CPU but increase in custodial storage. Second tranche of Tier-2 hardware grants all issued Bridging posts for EGEE-funded staff Travel costs £173k for 09/10 – within budget Small amount of funding for R-GMA over 6 months 24/8/10

21 GridPP24, Ambleside And the view is… 24/8/10 Panoramic?
