GeneratorM.Berggren, J.Tian

• no news yet onproblem with cross section of samples with virtual photons • still work in progress w/ Whizard authors

• adapting TrueJet code running with new MCParticle format • observed a chance for double counting in generation w/ 3f events

• no problem in samples produced so far (real photons) • need to adjust the cuts appropriately • work in progress …

• observed technical issue w/ 94 objects (created in Pythia): • for Higgs samples the di-quark input into 94 object has total cms energy • output of final state particles for simulation seems OK

• to be sorted out/ understood

SimulationD.Jeans

• continued to investigate spurious crashes observed in running mass production

• ~ one per mille of 2f -> had jobs crashed

• currently investigating on suspicious event…

• given the low occurrence of this, SW convenors agreed that this is not a problem for current production

ReconstructionR.Ete

• RE: started work on more realistic time measurement in Calorimeter Digitizer

• will have a report in a future SW&Ana meeting

• MB: adapted TrueJet processor to new MCParticle format in generated files

• discussion how to provide backward-compatibility

• agreement to aim for a new iLCSoft release for analysis in Q1 next year:

• improvements in HLR tools

• minor bug fix in LCIO

• EventSummary files

check status of production at this web page: https://ild.ngt.ndu.ac.jp/mc-prod/prodmon/prodsum-mc2020.html

• HO finished re-submission of some unfinished jobs in production so far

• will soon start production of some of the aa->2f/3f files

• with this we will then have all generated samples at least partially run through the

• discussion with French colleagues about SDHCal production and additional computing resources to be made available at IN2P3 site in Lyon

• storage and compute power

ILD Analysis and ML with JuliaTutorial by Jan Strube, PNNL

• Topics:

• introduction to Julia

• Julia on the DESY Jupyterhub

• Julia on the DESY NAF / KEKCC as an alternative

• first steps with LCIO (using the recoil mass / btag examples)

• plotting with Julia

• first steps with deep learning (using a simple calorimeter calibration as example)

• Q&A
