# 201020: Software Meeting

Agenda: https://indico.cern.ch/event/967456/

Connected:
Present: Placido, Andre, Valentin

Apologies:

## MC Generators

* Some issue with using integrated processes, still takes long time when using the files
    * Solution proposed by Whizard authors: simulate one event to trigger additional calculations by Whizard for the resonance history
    * Works locally, runs much faster.
    * Issues with running on the grid: still take too long, or use too much memory, or both, for 4q2l sample
    * 2q4l samples running fine, 3% failure rate (acceptable)
    * Check with VTune (or prmon) for looking at memory usage
        * VTune: `source /cvmfs/projects.cern.ch/intelsw/psxe/linux/all-setup.sh`
        * Prmon: https://github.com/HSF/prmon
        * SystemMonitor app
    

## 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

## iLCDirac

* New version coming ASAP
    * DiracOS v1r11 tested
* Calice moving from LCG FileCatalog to DFC, keep v6r22 with lcg bundles, because those contain LFC bindings still

## key4hep

### CI

* https://cern.service-now.com/service-portal?id=ticket&table=u_request_fulfillment&n=RQF1650416
* iLCSoft deployment: https://gitlab.cern.ch/CLICdp/SoftwareConfigurations/iLCSoft

* Nightly build

* Working on incremental builds and deployments
    * Will be controlled from gitlab

#### Environment Script

* Overwrite PATH etc.?
    * lcg stack prepend
* Module way is slow

* `spack environment`, like the key4hep-stack bundle package

* adapt the CVMFS publisher to create the script

#### View

* WIP, also Thomas Madlener looking into it

### k4-spack

* updated key4hep-stack bundle package
    * PR:

### LCFIPlus inside Gaudi

* Valentin looking into it because of interest from FCC side

### podio

### EDM4hep

### Core

* k4run
    * Done

### MarlinWrapper

* addded further test for converter
* Implement constant and "include" features used in Marlin XML

#### LCIO <-> EDM4hep conversions

* Conversion service from Gaudi
    * under investigation by Valentin
    * At the moment only used for geometry conversion
* How to do this most generically?
* How to tell which collections to import and export for given wrapper processor?
*

### spack

* heppdt is "back"
* python version to be made explicit
    * Added to packages.yaml
    * bug in concretizer that the python versions clash?
        * Open issue for spack
* how to define stack releases?
    * yaml file
    * directly in the package.py, or via import therer

### Gaudi

## FCCee Detector Model

* Some drivers used from lcgeo moving to FCC or better DD4hep repository

## SCT Integration

* Issue with compiling DDG4 on novosibirsk cluster
   * Added: DDRec DDDetectors UtilityApps

## Snowmass

## AOB
