Introduction

If we do a hackathon we need to know the topics!

But generally people were keen
Suggestion to try and book the IdeaSquare at CERN
ACTION Frank and Graeme to ask management about next AIDAinnova general meeting to try and pin down dates

WP12 papers at ACAT? Would be good to have a list so that we can let everyone know. ACTION on task leaders.

Quite a few papers around ACTS, don’t know how many get the AIDAinnova stamp though (Hadrien) but on the IJCLab side there’s a poster by Sylvain

Next CHEP is deleyed until 2023. Grapevine suggests there may be an in-person ACAT in autumn 2022 in Europe.

For multithreading, the IHEP work gathers a lot of great experience.

On the LHCb side parallelism is per-event
On the ATLAS side the parallelism is intra-event as well
Outside of the Gaudi ecosystem, most frameworks went for event parallelization granularity, with CMS as a notable exception. Need for parallelizing within the processing of a single event comes from having large events.
ACTS would be happy to share their experiences (at the hackathon) - particularly with how to handle conditions

Lamarr, focused on LHCb for now, but Gaussino should make it independent. We wonder how the geometry is described - is it DD4hep?

uRWELL simulation was studied in a testbeam and the data is now being studied, so things are nicely on track.

Q. Will Key4hep be distributed as a container?
A. Can they use the Key4hep distribution taking the software from CVMFS (from a lightweight C7 container if needed)?
- Spack can build containers, but beware that debug information would be included by default, blowing up the image size (can tell Spack to strip)
Q. HSF reviewed DUNE framework needs earlier this year. What are DUNE using as a software framework?
A. At them moment they are using art, which is developed and supported by Fermlab. Will try to find out is there are other possibilities.
