WLCG MoU Signature Status Brazil Since the April 2009 C-RRB meeting, FAPESP, the Research Council for the State of São Paulo, Brazil, has signed the WLCG MoU supporting the CMS experiment on behalf of the Tier centers of the State The Scientific and Technical Committee of the Brazilian Network on High Energy Physics - RENAFAE intend to coordinate the participation of all other Tier centers as a federation. Therefore, another WLCG MoU for all other Brazilian Tier centers will be signed by RENAFAE, as soon its legal board approves the document Some other countries have expressed interest in becoming Tier-2 centers, follow-up is on-going and resulting MoU signatures will be reported on at future meetings

WLCG Budget Estimates in MCHF 2009-2013

WLCG Funding and expenditure Personnel expenditure in slide 5 is based on: Current personnel commitments Planned replacements New requests waiting management approval There is a risk of personnel overspend particularly in 2010 (EGEE-III end, new requests) with continued but reduced deficit from 2011-2013 Materials funding has changed significantly since the April C-RRB: Original funding plan for the replacement Computer Centre spanned over 10 years Strategy end 2008/early 2009 required compression of funding into 3 years (2010-2012) New strategy under discussion which will impact timescale and new funding profile Evolution on both personnel and materials funding and expenditure to be reported at next meeting

CERN and Tier-1 Accounting January 2009-August 2009

Accounting for CERN and the Tier-1s Tier-1 reporting started in 2006. Monthly & annual reports available on WLCG website The graphs on slide 7 show a summary of CPU, Disk and Tape Storage accounting for January-August 2009 for CERN and the Tier-1s green line indicates installed capacity pink dotted line indicates the pledged capacities bars show the usage of the resource, colour-coded for each of the four experiments Normally pledge values should have changed in April to those of 2009, however exceptionally it was agreed (WLCG MB) to revise the procurement and installation plan and move to 2009 pledges in September Much installation work is currently ongoing and the monthly accounting reports will continue to be closely monitored

T2 Accounting August 2009 status

T2 Accounting August 2009 status

Accounting for Tier-2s Since September 2007 monthly reports are produced, circulated for comment and published on the WLCG website Slides 9 and 10 show the comparison of MoU pledge with CPU used for August 2009, ordered by pledge value Graphs show globally CPU used is well above 100% July 2009 : 180% August 2009 : 190 % September 2009 (draft report) : 201% As for Tier1 sites, 2008 pledges being used until September 2009 Currently most of the 64 Tier-2 Federations are reporting accounting data over a total of 124 sites Follow-up is ongoing with sites repeatedly showing no or low accounting performance to rectify this before data taking

Current Experiment Requirements and Computing Resource Pledges

Pledge collection exercise Following LHCC and Scrutiny Group deliberations revised requirements were communicated to the sites on 08/09/09 Sites were asked to comment on their 2009 installations and confirm 2010 pledges – deadline 28/09/09 (already announced at April C-RRB) exceptionally no input required beyond 2010 By 21/09/09 little input received => reminder By 28/09/09 input from some sites still missing (2 Tier-1s, 8 Tier-2s) and some input preliminary awaiting confirmation by official bodies On 05/10/09 change signaled to the ATLAS T1 2010 CPU requirement On 07/10/09 preliminary resource tables published for C-RRB meeting

2009 pledge installation status Can be classified into 3 main categories Installation complete or completion planned by end October Installation has progressed well with a revised installation schedule agreed with the experiment(s) following publication of their revised requirements Installation delayed for procurement reasons, currently on-going and planned to be complete in November or December 2009 2009 confirmed pledges remain unchanged (despite requests by some sites) Confirmed pledges cannot be changed Some sites already fully installed their 2009 pledge Original pledges not fully installed signaled by accompanying note in Resource Tables 2009: an exceptional year resulting in a later change to 2009 pledge values for reporting

Preliminary Pledge Balance 2010 2010 pledges against latest requirements % balance Status below that of 07/10/09 – will still change Certain sites have signaled preliminary information waiting approval by official bodies: T1: FZK (Germany), NDGF (Nordic Data Grid Facility) T2: Norway, Sweden, Russia (2010 pledge confirmed, experiment split only available in December/January) Since publication revised 2010 pledges received from US ATLAS Tier-2s, IN2P3 T1 & T2 Certain sites unhappy with the late ATLAS TI CPU change with respect to confirmed pledges submitted 2010 ALICE ATLAS CMS LHCb Sum 2010 T1 CPU -9% 10% 6% -5% 5% T1 Disk -40% 8% -4% 17% T1 Tape -44% 18% 66% -3% T2 CPU -25% 24% -12% T2 Disk -72% -31% 37% - -22%

Requirements/Pledge process – how to improve ? Final 2010 confirmed pledge tables only available in December/January following the relevant official meetings (should be approved at Autumn C-RRB) Too late to improve for 2009, but we must improve in future Proposed timescale: Experiment requirements discussed and approved by LHCC & C-RSG bodies in February/March Announced to Funding Agencies via April C-RRB meeting Pledge input requested for end September including confirmed pledges for the following year and planned pledges beyond Final tables approved at Autumn C-RRB meeting allowing more time for procurement cycle Flexibility will be required for 2010 to allow enough data-taking to influence revised requirements

Conclusions WLCG MoU: Brazil Tier-2 signed since April C-RRB, another federated Tier-2 expected in future. Follow-up on-going with other interested countries WLCG Funding & Expenditure: some future over-spending estimated on personnel. Once replacement Computer Centre strategy finalised, materials funding and expenditure to be re-aligned accordingly Monitoring ofTier-1 and Tier-2 accounting continues. 2009 pledge values start after September. Follow-up on-going with Tier-2 sites with little/no accounting activity Recent pledge collection exercise still not concluded Special year, confirmed requirements communicated very late (+ one later change) Definitive situation can only be published in December 2009 or January 2010 Process must change for the future to allow formal approval of pledge tables at Autumn C-RRB meeting
