Attending

Present/Contributing: Graeme Stewart, Eduardo Rodrigues, Benedikt Hegner, Pere Mato, Stefan Roiser, Michel Jouvin

Apologies: Liz Sexton-Kennedy, Nicole Skidmore, Paul Laycock, Torre Wenaus

Discussions with Activity Areas

Any discussions to report on?

Activity	SG Responsible	Met?
Data Analysis	Eduardo + Mark
Detector Simulation	Torre + Graeme
Physics Generators	Liz + Stefan	Y
JuliaHEP	Pere	Y (implicit)
PyHEP	Eduardo	Y (implicit)
Reconstruction and Software Triggers	Michel + Paul
Tools and Packaging	Liz + 1 more?
Training	Graeme + Nicole	Y

Torre has drafted an email to send to simulation conveners, so hopefully meeting soon.

There is some discussion about packaging tools in Belle II, Pere will pass this on to Liz.

• Need one more SG member to also cover the tools and packaging area with Liz

European Strategy Update 2025

Key areas: generators, simulation, reconstruction, analysis and training/careers.

We need a team to manage this process and organise the work with the conveners and the wider community.

Volunteers: Michel, Graeme, …

Feedback from coordination meeting? Not so far.

• Michel, Graeme to reach out to activity conveners

HSF and SFT reporting to WLCG/LHCC

• Eduardo presented to the LHCC on Sep. 10th the “HSF/community Software Report”.
  • Very well received.
  • The LHCC commends the HSF for its evolution and ongoing reorganisation efforts. It also congratulates us on our software stewardship role within the community (e.g., successful PyHEP initiatives, efforts to explore the role of Julia in HEP, the highly appreciated training programme).
• Eduardo submitted the part “HSF and Community Software Activities” for the October RRB report. (Thank you as ever for the comments/inputs.)
  • This incorporated updates from community projects, such as IRIS-HEP and SWIFT-HEP, as well as from the HSF.

Seminar Series

Indico; Coordinators: Benedikt, Michel, Andrea

• 1 October, Julia in high-energy physics: a paradigm shift or just another tool?
• 30 October, Reconstruction? (Apparently they contacted speakers)

• 27 November, Generators?

• Benedikt will follow-up.

HSF Affiliated Projects

Project document was circulated to the HSF ~2 weeks ago.

Graeme got some private questions on qualifying projects from ATLAS colleagues, e.g., did experiment software count.

A few comments on the guidelines document re. stability of maintainers from Alex.

• Should not be “downgrading” projects, but encouraging investment

Next steps - Pere and Eduardo to take care of

• Light revision and move to website
• Concrete project engagement

Advisory Group

No further comments on the document, so we can proceed.

Initial list of members:

• LHC Expts
• DUNE
• Belle II
• “Small” experiments
• MCNet

Next steps:

• Graeme to draft an email for comments, then contact initial list.
  • It’s here
• Advisory Group mandate should go onto the website.
• Invitations to computing coordinators / MCnet chairs (not sure for small experiments - Pere and Graeme will have a coffee with the CERN rep.)

It was felt that ePIC/EIC and FCC were a bit immature yet to join the AG, but should look again to other potential members from running experiments at other labs. But in any case, go ahead inviting the above.

AOB

Coordination Meetings

Chairing sign up document. We need a few more volunteers from now until the end of the year!

Domain

Torre made enquiries with BNL who seem to be willing to take over ownership of the domain.

HSF on Google (and other platforms)

Check accounts used and that information is shared correctly.

Platform	HSF Account	Notes
Google	hepsoftware@gmail.com	Calendar and YouTube
Zenodo	hsf-editorial-secretariat@googlegroups.com	Better to have individual accounts manage the community
ORCID	0000-0002-6574-1593	Because of Zenodo? Probably not needed
Twitter/X	hepsoftfound	Probably not going back…

At least Graeme has these passwords and they can be shared in the Steering Group.

Next Meeting

To get out of phase with LHCb software board meetings, next SG meeting in 3 weeks time, 14 October: https://indico.cern.ch/event/1459900/.
