AIDAinnova WP12 - General Meeting

Introduction

• meeting schedule and next meting
  • agreed to have a 8 weeks schedule
  • next meeting Aug 26
  • try to have a report from every task
    • potentially from deputy if the primary task leader isn’t available

Turnkey Software

• Key4hep highlights

  • k4simDelphes, k4MarlinWrapper
  • migration ongoing at FCC, CEPC, MuonColl
    • Padua working on muon collider an transition to Key4hep

• PODIO/EDM4hep highlights

  • started work on schema evolution
  • many other features/improvements
  • open issue for EDM4hep: how to best handle (generic) user data

• DDDigi

  • work started (non trivial task)
  • would need a ‘customer’

• INFN

  • looked into CMSSW about heterogenous computing parts

• IHEP

  • also started work on heterogenous computing
  • S.Blyth will start to work there

• For DDDigi customer we think FCC were interested - to follow-up with Markus (and Geri, Clement)

  • also plan to have a dedicated DD4hep meeting on this

Simulation

• Witek replacing Anna until mid Sep.
• Manchester
  • started work to port Lamarr to generic HEP
• IJClab
  • work yet to be started
• DESY
  • progress w/ angular conditioning GANs
• CERN
  • plan to hire a project associate for sim task
  • work on comparing inference libraries LWTNN and ONNX
  • VAE w/ conditioning on calorimeter technology
  • started new forum ML4Sim https://indico.cern.ch/category/13860/

Track Reconstruction

• some work/discussion started on using DDRec tracking surfaces in ACTS
• detray is targeting heterogeneous resources, will be able to be templated for your environment
  • this will be the connection point for navigation and propagation, for Key4hep
• INFN
  • working on simulation of uRwell gaseous detectors
  • need to understand the impact of the diamond layer coating, linked to hardware study
• IJCLab
  • looking into what prevents further ACTS experimentation in Belle 2
    • need support for detectors that are not surface-based (CDC for Belle 2, also of interest to sPHENIX)
  • hired PhD to work on GPU computing
  • job offer for post doc (mainly centered on GPU and ML activities)

Particle Flow Reconstruction

• dual readout calorimeter (IDEA)
  • started to adopt EDM4hep for the simulation
  • writing two collections (scint/cherenkov)
• APRIL PFA
  • including timing in PFA clustering
  • some inspiration from CMS HGCal reconstruction
• DUNE near detector
  • adapting LArTPC/ILC algorithms to ND
  • plans to hire 0.5 post doc at University of Cambridge
