Attendees: Juan, Mateusz, Andre, Leonhard
Apologies: Swathi
Date: October 29
## News
* Please put Friday, SFT retreat, as Duty travel in EDH
## Round The Table
### Leonhard
* More optimal observable figures after some bug fixes
* more debugging needed
* Plots made from madgraph generated files
* Optimal obversables assume no W-width
* podio data source takes too much memory?
* 50 MBit/s throughput at the moment
* memory leak?
* ECFA ECR meeting:
* Leonhard organiser (1/6) of future collider working group
### Andre
* NTR
### Mateusz
* Timings in workflow not calculated using truncated average, so first event was greatly affecting results because of loading condition data etc.
* New julia release: 1.11, using new features to use unregistered packages (graphml)
* Julia runtest merged PR, can now put arguments in tests. released as well.
* EventCounter PR for k4FWCore
### Juan
* Chep
* Spack talk:
* scott snyder complained about development workflow
* Marco asked about running things in parallel
* Talk after: FNAL person presenting LArSoft, talked about using spack for development with a command on top of spack
* Gaudi talk:
* Marco commented about upstreaming some reading/writing from Key4hep, similar to what LHCb has, but nothing like this in Gaudi
* New key4hep-release with some fix for Delphes (Birgit)
* Looked at ACTS stuff from the Muon Collider
* No ACTS-Geo Service, but parts of geometry hard-coded, or write json file
* Revived ACTS service, started seeding algorithm, trying track fit, all with ODD geometry
* Then worry about geometry stuff later
* Track finding not yet working
* Try what the EIC people are doing? (pointers to be provided by Leonhard); now EIC moved to Jana2 with tracking algorithm could also be interesting
