    # 200414: Software Meeting

    Agenda: https://indico.cern.ch/event/909144/

    Connected: Andre, Matthias, Marko, Placido, Ulrike, Valentin, Philipp,

    ## Long lived particles

    * Update with ctau=6.9mm samples
    * Fix for "reconstructable" definition, select with nHits>=3 instead of >=0
        * Should use MCParticle hits instead of hits of reconstructed tracks

    * PR: need to have a look at the background
        * EB: Already some look by Cecilia
        * US: Get number of background events to be able to optimise selection, e.g. against significance
        * PR See last presentation by Emilia

    * US: Duplicates for low_pt pion tracks, some way to reduce them?
        * Compare track parameters to reduce duplicates

    ## MC Generators

    ## Simulation

    ## Reconstruction

    ### Tracking

    ### Particle Flow

    * MW: discussed what goes into the data file, and use Matthias' settings as defaults as more general
        * Default Plots: JE Response, JE Resolution, Polar and Azimuthal angle resolution
        * Optional Plots: MET, Di_Jet mass resolution plots
    * Need to align use of histogram, could be finished this week

    ## Infrastructure

    * Need to configure LCG_97 based installation tarball to CVMFS
    * Could not use cvmfs based installation
    * /cvmfs/clicdp.cern.ch/software/LCG/97/x86_64-centos7-gcc8-opt/
        * Same as 97 minus DD4hep and LCIO
        * Can be also in SFT cvmfs? Valentin to ask Gerri
    * TODO: remove also gaudi from there
    * TODO: layered view: select packages (Geant4, ROOT,...), let it create the links

    ## iLCDirac
    * New version coming ASAP
        * DiracOS v1r11

    ## key4hep

    * Base on Gaudi branch
        * https://gitlab.cern.ch/gaudi/Gaudi/-/merge_requests/986
        * https://gitlab.cern.ch/clemenci/Gaudi/-/tree/cmake-modernisation
        * dev3 or dev4 lcg builds
        * Once we have an idea, deploy to key4hep

    ### podio/edm4hep/core/nightlies

    * Key4hep builds: added spack mirror over http
    * cvmfs publisher as gitlab runner?
        * Depends who owns the publisher
    * tagging scripts: https://github.com/iLCSoft/iLCInstall
        * scripts/ilcsofttagger.py

    ### MarlinWrapper

    * Marlinprocessor is running,
        * but segmentation fault at the end of Gaudi under investigation
        * pointing at libMarlin.so

    ## AOB
