Computing Operations Report 29 Jan – 7 June 2015 Stefan Roiser NCB 8 June 2015

Resource Usage Online will mostly not be available during Run 2 86 % MCSimulation 12 % User Our 9 T0/1 sites are among the first 12 sites + – 1 st Online farm – 7 th Yandex – 10 th St de Compostela Simulation dominates – will change for next report ;-) Decent utilization of pledges 8 June '15NCB - Operations Report - StR2

Efficiency Done+Completed = 95.4 % successful jobs Simulation, 87 % CPU User Jobs, 11 % CPU Run 2 workflow validation MCStripping, 0,76 ‰ wall Job Success Rate CPU Efficiency NB: Completed job did process successful, just the output file is uploaded with delay to destination Organized workflows with very high CPU efficiency, ( except MCStripping, consumes very little time) * User jobs ~ >80 % 8 June '15NCB - Operations Report - StR3

Run 2 Offline Workflow Validation First files (3 runs) for offline processing available last Friday – Managed to test all data processing workflows 11 different productions in 4 streams out of the pit – No major issues, few small ones LHCbDIRAC issues fixed on the spot Application problems identified and patches rolled out – Will continue with validation after polarity switch tonight with new data Very good collaboration of all involved parties !!! 8 June '15NCB - Operations Report - StR4

TIER2D STATUS Slides from Andrew McNab 8 June '15NCB - Operations Report - StR5

T2-D Status - - June 2015 LHCb NCB Current sites  Now 10(9) official T2-Ds − dCache: CSCS.ch, IHEP.su, RAL-HEP.uk, UKI-LT2-IC-HEP.uk − DPM: CPPM.fr, LAL.fr, LPNHE.fr, Manchester.uk, NCBJ.pl, NIPNE- 07.ro  LAL.fr and LPNHE.fr share some infrastructure and offered 300TB together  Sites agreed to provide 300TB for start of Run 2  Difficult to try to enforce this as we ’ re not yet filling them up  More candidates:  CBPF not currently an official T2-D, still in test  DESY-HH, Syracase, and Yandex are also in various stages of discussion  Two other UK sites in discussion dependent on GridPP5

T2-D Status - - June 2015 LHCb NCB Capacity at Run 2 startup  Already at 2427 TB online and accessible to analysis jobs today − Which surpasses the 2015 request of 1.9 PB  If 9 offers of 300TB, then at least 2700 TB should be available − Should be even more (eg RAL-HEP already providing 460 TB)  If three more join and so 12 offers of 300 TB, then at least 3600 TB will be available. − Which is not that far from the 2016 request of 4 PB  Any of these scenarios (including today's status) mean the original goal of providing storage comparable to another Tier-1 has been achieved.
