Generator Services planning meeting Witek Pokorski 30.11.2007
2
Outline Introduction Progress report Planning for the next 6 months Summary
3
Introduction Previous (second) Generator Services planning meeting on the 25th May 2007 slides and minutes available from http://indico.cern.ch/conferenceDisplay.py?confId=16569 Regular monthly meetings with technical presentations well attended, productive discussions Purpose of the present meeting to review the progress since last meeting to plan the work for next 6 months
4
Work-packages generator libraries repository [GENSER] testing and validation of generators [VALIDATION] first level support [SUPPORT] event record and particle properties [HEPMC] event database [MCDB]
5
Highlights of last meeting new structure of GENSER deployed and used by experiments no changes suggested plan to further extend the testing distribution tests/validation suggested by LHCb plan to collaborate with Rivet/CEDAR for validation experiments moving to HepMC 2 MCDB - maintenance only
6
Progress report GENSER structure stable and used by experiments 22 generators installed http://lcgapp.cern.ch/project/simu/generator/ 5 new added on request of experiments since the last review Cascade, Charybdis, Isajet, Phojet, Winhac 2 more to be installed MC@NLO, POWHEG MC@NLO first few generators build on Windows Pythia6, LHAPDF, Photos more requested will need to be automatised dedicated person will come in March 2008
7
Progress report Validation all generators tested (at least one test per generator) all tests requested by experiments (LHCb) implemented b-bbar cross sections, mutliplicities, etc new tests with distributions plotted Pt, Eta distributions results presented on web page comparison between different versions of generators (Pythia6) first physics validation implemented using Rivet Pythia6 vs D0 Run I, W production differential fruitful collaboration with Rivet/CEDAR
8
Progress report regular releases of HepMC 2 new features include: number of multi-parton interactions stored in GenEvent, pointers to beam particles added, reproducibility of ordering of particles solved work done on adapting HepMC for ROOT I/O std::set replaced by std::vector ATLAS and LHCb moving to HepMC2 CMS has already moved HepPDT simple (text) particle table introduced MCDB started integration in CMSSW
9
Milestones overview GENSER_101/12/2007include new versions of supported generators GENSER_201/09/2007provide windows binaries for main generator(s) GENSER_301/09/2007study possible integration of MC@NLO VALIDATION_101/08/2007implement tests requested by LHCb VALIDATION_201/11/2007 implement tests dedicated to CMS and ATLAS validation VALIDATION_301/09/2007 provide web interface to distributions/histograms from the tests VALIDATION_401/10/2007get Rivet running within GENSER HEPMC_101/09/2007complete HepMC2 testing with ROOT I/O HEPMC_201/12/2007move to HepMC2 (ATLAS and LHCb) DONE ONGOING waiting for input
10
Manpower overview satisfactory number of FTE ~1.5 FTE for GENSER, ~0.5FTE for MCDB unsatisfactory rotation of people 1 out of 3 original GENSER integrators available 4 new integrators delays due to learning phases non regular visits contribution of some integrators limited to only one visit inefficient investment of effort long term plan of regular visits should be put in place W.P. will leave the project end of January 2008 new project leader will need to be appointed
11
Proposed plans GENSER continuation of the same service Validation implementation of new tests from experiments (ATLAS ?, CMS ?) collaboration with Rivet/CEDAR implementation of new Rivet-based physics validations HepMC complete migration to HepMC by LHC experiments MCDB complete integration in CMSSW
12
Proposed milestones GENSER_101/06/2008include new versions of supported generators GENSER_201/03/2008include POWHEG and MC@NLO VALIDATION_101/03/2008 get input from ATLAS and CMS for new tests and implement them VALIDATION_201/06/2008extend Rivet validation to new C++ generators HEPMC_101/03/2008complete migration to HepMC2 MCDB_101/06/2008integrate MCDB in CMSSW
13
Summary project running according to the plan GENSER stable validation extended regular technical meetings more physics validation proposed collaboration with Rivet next planning meeting May/June 2008 new project leader before end of January 2008
