Presentation Transcript

  1. Preparation of KIPT (Kharkov) computing facilities for CMS data analysis L. Levchuk Kharkov Institute of Physics and Technology (KIPT), Kharkov, Ukraine

  2. WLCG infrastructure of the CMS experiment (CMS computing model) • KIPT T2 center (T2_UA_KIPT): status and prospects • Summary L.Levchuk, NEC'09, Varna, Bulgaria

  3. CERN: acquisition, first-pass reconstruction, storage & distribution 1.25 GB/sec (heavy ions) L.Levchuk, NEC'09, Varna, Bulgaria 3 Ian.Bird@cern.ch

  4. CMS Physics Goals CMS is expected to shed light on • origin of particle masses (search for Higgs boson for all possible MH: does it really exist?) • origin of “dark matter” in the Universe (search for SUSY signals) • origin of asymmetry matter/antimatter in the Universe (study of CP violation in B decays) • whether new states of hadronic matter exist (study of heavy ion collisions) • if any “exotica” can emerge at the TeV (1012 eV)) scale L.Levchuk, NEC'09, Varna, Bulgaria

  5. CMS Computing Model CMS trigger T0_CH_CERN  RAW ~1-3 MB/evt ~100 evt/s  L.Levchuk, NEC'09, Varna, Bulgaria

  7. KIPT CMS Computing Facility Storage Element (SE, SRM): 12 nodes (24 CPU’s Intel Xeon EM64T: 203.2 + 42.8 GHz) 11SATA RAID5 (400 GB disks) +1 SATA RAID6 (1.0 TB disks) SRM space: ~ 50 TB(currently), upgrade to ~120 TBby LHC startup (end of 2009) Type:DPM (SLC4) Worker Nodes (WN): 68x86-64 CPU cores (Intel Xeon EM64T 3.4 GHz & E5420 2.5GHz), 0.5 kHEPSPEC06 HEPSPEC06 Benchmark Results: L.Levchuk, NEC'09, Varna, Bulgaria

  8. KIPT CMS Computing Facility Year 2001 – RH Linux cluster of a few dual PIII nodes from 2002 on – participation in CMS Monte Carlo production 2003 – Grid middleware (LCG2) deployed for the first time from 2005 on– the site registered in WLCG (Kharkov-KIPT-LCG2) from 2007 on– SLC cluster built on x86-64 CPU platform 2008– CMS software (CMSSW & PhEDEx) deployment; site registration in CMS SiteDB (T2_UA_KIPT) 2009 (June)– successful commissioning of T2_UA_KIPT 2009 (July) – T2_UA_KIPT is in “Production” (“Ready” > 80% of time) !!! Up to now, the KIPT computing facility remains to be - the only active WLCG/EGEE site of Ukraine; - the only CMS RDMS T2 site, which is non-”_RU_” L.Levchuk, NEC'09, Varna, Bulgaria

  9. Conditions for site ‘Readiness’ The CMS site readiness takes into account several sources of information to define whether a site is in a good status: site availability according to the CMSSite Availability Monitor (SAM) tests 16 CMS-specific critical tests of CE, SRM (SE) and CMS software in addition to “routine” WLCG SAM tests; daily SAM availability must be 80%  fraction of successful jobs submitted by theJob Robot automatic submission and management of“fake”CMS analysis jobs via WLCG (using CRAB) (typically, 6×100 jobs/day); daily JR efficiency must be 80%  number of operational links connecting the site with other sites number of commissioned links TO Tier-1 sites ≥ 2 (to commission one such link, site has to sustain ≥ 5 MB/s of LoadTest during 24 hours) number of commissioned links FROM Tier-1 sites ≥ 4 (to commission one such link, site has to sustain ≥ 20 MB/s of LoadTest during 24 hours) L.Levchuk, NEC'09, Varna, Bulgaria

  16. Resources: available vs. needed For 2-nd half of 2009: storage upgrade up to 120 TB Major upgrade of CPU capacity is planned for 2010 No problem to have connectivity of 1 Gbit/s right now L.Levchuk, NEC'09, Varna, Bulgaria

  17. SUMMARY • Preparation of KIPT WLCG infrastructure for CMS data analysis is in good progress • Site T2_UA_KIPT is commissioned (‘Ready’) • Site T2_UA_KIPT is stable (‘Ready’ >80% of time) • Upgrade of hardware to fit CMS Computing TDR requirements is still needed L.Levchuk, NEC'09, Varna, Bulgaria
