# 210804: Software Meeting
Agenda: https://indico.cern.ch/event/1064845/
Connected: Raffaela
Present: Andre, Placido, Valentin
Apologies:
## Proceedings/Talks/etc.
## Summer Student project
- https://codimd.web.cern.ch/omk0BJcXTqiITllS-JGlLQ?edit#
- [ ] fetch downstream changes from Muon Collider fork of DDDigiPlanarProcessor
## MC Generators
## CLICDet Delphes Card
## Simulation
* Issue with simulation of muons with fixed pT?
* observed different duplicate vs phi using different muon simulation runs
* Maybe different input (not pt, but energy)?
* Different Theta range, 0-90 degrees before, 0-180 degrees now
## Reconstruction
### Tracking
### Particle Flow
### Digitizer
### Event Display
### FlavourTagging
### Long-Lived Particle
### dE/dX
### LCGeo Test
## Infrastructure
### Sanitizers/Compilers
Placido: Investigating Santizers for the MarlinWrapper, but cannot compile due to Kernel issue

[ 7%] Linking CXX shared module libLcio2EDM4hep.so
==1077==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
==1077==ASan shadow was supposed to be located in the [0x00007fff7000-0x10007fff7fff] range.
==1077==This might be related to ELF_ET_DYN_BASE change in Linux 4.12.
==1077==See https://github.com/google/sanitizers/issues/856 for possible workarounds.
==1077==Process memory map follows:

## iLCDirac
* FCC VO
* EOS integrated
* Cannot be in more than one VO

* Cannot run key4hep stack with Broadwell on cern HTCondor
```
/bin/sh: line 1: 555 Illegal instruction (core dumped) ./DelphesPythia8_EDM4HEP ./edm4hep-delphes-lhe-examples/simdelphes/delphes_card_IDEA.tcl ./edm4hep-delphes-lhe-examples/simdelphes/edm4hep_output_config.tcl ./edm4hep-delphes-lhe-examples/cards/Pythia_LHEinput.cmd edm4hep_test_output.root
```
* add key4hep-stack to config (gaudiapp)
* k4run executable (modifiable)
* Test Clic Reco With GaudiWrapper inside iLCDirac
* InputFiles
* --EventDataSvc
* --LcioInput
* RandomSeed
* Not fully implemented in vanilla Gaudi
* Should implement something in Gaudi like the randomseeder in Marlin
* OutputFile
* PodioOutput
* CompactFile
* -->GeoSvc (to come to k4Sim)
* NumberOfEvents
* -n , --ApplicationMgr.EvtMax
## Key4hep
* build with gentoo-prefix almost working, except some packages
* header, include things
* whizard2 tricky
### Gaudi
* Writing guide for upgrading to new gaudi cmake
* updated documentation for gaudi, only needs deployment now
* https://gitlab.cern.ch/gaudi/Gaudi/-/blob/4b5340fbc9afa82ab1434721870d40665bf4df54/docs/source/Developers/cmake.rst
* https://gitlab.cern.ch/gaudi/Gaudi/-/merge_requests/1152
* Doc: gaudi.web.cern.ch
* Documentation for functional:
* https://lhcb.github.io/DevelopKit/
* Make a service optional/disable in config file: Ticket with Gaudi
* https://gitlab.cern.ch/gaudi/Gaudi/-/issues/178
### CI
* CVMFS deploy from gitlab: https://cern.service-now.com/service-portal?id=ticket&table=u_request_fulfillment&n=RQF1650416
* --> Need to re-open the ticket (Valentin)
* gitlab-runner was missing permissions
* New ticket: https://cern.service-now.com/service-portal?id=ticket&table=u_request_fulfillment&n=RQF1747119
* IT will fix the gitlab integration on another repo and then replay the steps on sw.hsf{-nightlies}.org
### Environment Script
### View
### key4hep-spack/spack
### podio
### EDM4hep
* Need TrackerHitPlane class in EDM4hep
* UserClasses, discuss in podio/edm4hep meeting if direct access to underlying pods is possible or desirable
* Test writing sample event data:
* Incomplete, e.g., TrackCollection not written
* Would also be useful for testing EDM4hep <-> LCIO Conversion
### k4FWCore
* getTypeOfCollection from NameOfCollection
* Can already get type from collection from base class
### k4MarlinWrapper
* LCRelation troubles because of mismatch between EDM4hep and LCIO way of doing relations
* geoSvc to replace MarlinDD4hep
* Need to set the GlobalTrackerReadoutEncodingStringID
### spack
Issue
Opened PRs for a bunch of improvements:
* [ ] fixes to fetching fastjet https://github.com/spack/spack/pull/20064
* [ ] special "commit" version for nightlies https://github.com/spack/spack/pull/20065
* Compiling everything with clang
* Issue with "base" packages, mesa
## FCCee Detector Model
## SCT Integration
### Using the lcgeo/ddsim/Marlin to run simulation and reconstruction
* Provide set up and instructions for running
* Do this now, use key4hep setup.sh from cvmfs
* run ddsim only with TPC (other detectors probably need geometry from aurora, which we cannot access)
* DDSim on cluster doesn't work because DD4hep too old and python mismatch
* run Marlin with reconstruction from https://gitlab.cern.ch/sailer/SCT_TPCReco/
* run wrapped reconstruction with LCIO until conversion from SimTrackerHit is available as well
* Integrating TPCSD sensitive into Aurora not so straight forward
* They directly use G4VSensitiveDetector instead of dd4hep::Geant4Action types.
* Also event data model differences need to be understood
* WIP: Add TPC xml as "Aurora" Package
* Part of simulation, but now need to create the hits.
