Report on PdmV Activities G. Boudoul, G. Franzoni, D. Piparo, J-R Vlimant

In a Nutshell ● Validation for 6.1 has to catch up and continue. ● ValDB is now in full production. ● For HLT validation, we need focus on DPG level validation, and more attention on Data. ● Validation for condition update @HLT and @Prompt run smoothly. ● Planning for Upgrade Validation coming are coming together. ● Event different in different dataset understood, and the magnitude of issue is being investigated. ● HCal laser pollution issue: the full list for all Pds is coming together. There already exists datasets that can be scrutinized.

Validation Organization https://twiki.cern.ch/twiki/bin/view/CMS/PdmVTasks#Validation ● Provide links to releases notes ➢ Maintained by the relevant experts ● Provide links to validation tasks: ➢ Offline, Conditions, HLT, Physics ● List of contacts ✔ https://twiki.cern.ch/twiki/bin/view/CMS/PdmV#Contacts ➢ Solely maintained in the relevant e-groups : no list maintained in twikis anymore ➔ Please notify PdmV conveners of any change, so as to keep efficient communications ● Validation Tables ✔ https://twiki.cern.ch/twiki/bin/view/CMS/PdmVValidationTables61X ➢ Deprecated and replaced by the usage of valDB https://twiki.cern.ch/twiki/bin/view/CMS/PdmVValDB ➢ Many issues fixed already, please report to us any problem or suggestion you might have ➔ From 6.1 pre4 on , only filing with valDB is necessary  HN post to relevant group is handled by valDB  Summary view in valDB ➔ (planning on twiki-like representation) PPD Meeting, PdmV report, J-R Vlimant

6.1 Validation Status ✔ 6.1 validation in valDB : http://tinyurl.com/8ljuzhs ➔ Keep up with the good work of validation, for those filing reports ➔ Coverage is still scarce and regardless of the scope of 6.1, validation must be performed. PPD Meeting, PdmV report, J-R Vlimant

Condition Update Validation ● Validation of weekly Cond@HLT ✔ https://twiki.cern.ch/twiki/bin/view/CMS/PdmVTriggerConditionValidation ➢ Has been running smoothly weekly by TPG  ReRun HLT with and w/o new conditions on an recent run  Restricted to hand full of validators in feedback ➔ In smooth production mode again ● Validation of bi-weekly Cond@PromptReco ✔ https://twiki.cern.ch/twiki/bin/view/CMS/PdmVPRConditionsValidation ➢ Has been running smoothly bi-weekly by PdmV  ReRun RECO with and w/o new conditions on a recent run  Restricted to hand full of validators in feedback  relMon between two different runs : available ➔ Keep tight connection with validators for quickest feedback. ➢ Planning is bi-weekly, any more frequent will have to make a case to PPD Coordination ➔ More in Loic's presentation today  Planning for full automation of the procedure down to validator feedback ➔ Using valDB ➔ Requires gui/web-interface design, DQM & valDB api PPD Meeting, PdmV report, J-R Vlimant

6.0 / Upgrade Validation https://twiki.cern.ch/twiki/bin/view/CMS/PdmVUpgradeValidation (developing...) ● Effort to integrating release validation on upgrade release on-going: ➔ Workflows integrated in standard matrix test ➔ New manpower for development, please volunteer to DPG/POG/PAG/TSG ● Release Validation Production ➢ Set of upgrade /GEN-SIM sample made in 6.0.1 ➔ More in presentations from Piet and Vadim today. ➢ “Identity test” for current geometry ✔ Exact identity test failed in production (understood, fixed, but not in time) ➢ “Almost idenity test” performed with 6.0.0 vs 6.0.1 http://cms-service-reldqm.web.cern.ch/cms-service-reldqm/ReleaseMonitoringSpecial/601_Full/  http://cms-service-reldqm.web.cern.ch/cms-service-reldqm/ReleaseMonitoringSpecial/601_Fast/  ➔ No relevant differences observed: Green light ● Plans ➢ Add the DQM developers and experts in the MC validation e-group to keep the communication with validators tight. ➢ Use of valDB ➢ Campaign for reminders to DPG coordination and all DPGs will start  Find developer & make sure that the existing validator can take care of upgrade validations ➢ Campaign on POG will follow, once the software is there.

Events Looking Different Feature ● Reported last week by Boris: https://indico.cern.ch/conferenceDisplay.py?confId=169318 ● Origin of the problem identified: https://hypernews.cern.ch/HyperNews/CMS/get/recoDevelopment/1162/1.html ● Every single events (MC & Data) processed 5.2 and 5.3 are affected ! ✗ Undetectable without looking at the event from two different datasets ● Fix for the bug available and will get into 6.X ✗ PFDisplacedVertexCandidateProducer use PVs from the previous event ✗ Get used in particle flow ✗ Get used in “rho” calculation ● Special build for 5.3 to address the amplitude of the issue ✔ Expected to be very small from developers ✔ Minimal samples should be available today ✔ Larger production will be done if effect is large.

HCal Laser Pollution https://twiki.cern.ch/twiki/bin/view/CMS/PdmVDataReprocessing534p2laserHCAL ● Solving with lumisection masking (certification) will amount to too much data thrown away ● Full list of events affected by the laser firing during collision needs to be done. Implies running a skimming on every single /RAW Physics datasets of 2012 ● Requests were send (Oct 24) http://cms-pdmv-stats.web.cern.ch/cms-pdmv-stats/?search=franzoni_laserHCALskim ✔ Fast on processing ✗ Overhead in I/O ✔ 63/80 announced ✔ Expecting the remaining 13 (4 of which might not be relevant) soon ● >~600K events are affected ● Fraction of event polluted (see next slide) ➔ Average 0.02% pollution ➔ HCalNZS ~80% (no worries) ➔ Up to 1% or 2% in 2012A due to a bias of the first run, not black listed in the skim ● BTag, MET, Photon, SingleMu, MB,... ● Ready for making the full list, once we get the remaining datasets ● Not so sure about the format in which to deliver the list... ● Dataset available ➢ /RAW-RECO produced and can be looked at by Analysis groups ➢ AOD @ CERN PPD Meeting, PdmV report, J-R Vlimant

HCal Laser Pollution Fraction % 1% ● Average 0.02% pollution # in skim ● HCalNZS ~80% (no worries) ● Up to 1% or 2% #in /RAW ➔ BTag, MET, Photon, SingleMu, MB,... No corrected for DCS only efficiency PPD Meeting, PdmV report, J-R Vlimant
