News, general matters, announcements
- Have all Activity Area (AA) conveners updated their pages with present and past conveners?
Steering Group & Advisory Group
- Co-organising the next WLCG/HSF Workshop, 2-6 November 2026 in Bologna: Converged on draft schedule of HSF parallel sessions.
- Anticipate a call for contributions!
- A significant rework of the Affiliation programme based on gathered experience from recent reviews and from community feedback has been done (thanks to Eduardo and Caterina, mainly). Check the updated details at https://hepsoftwarefoundation.org/projects/affiliated.html and https://hepsoftwarefoundation.org/projects/guidelines.html.
HSF Affiliated Projects and Software
Status at https://hepsoftwarefoundation.org/projects/projects.html - 6 projects affiliated as of today, with finalisation of the Dirac review (thanks to those involved).
Reviews underway:
- NoPayloadDB Conditions Database
Do not hesitate to discuss around you to identify relevant projects/libraries that could engage with the affiliation programme. AA conveners are in an excellent position to help us identify which projects to prioritise to join the affiliation programme.
AI in contributions to HSF repositories
Feedback still welcome: So far HSF repositories do not provide any statement on AI-powered/-helped contributions, and we are starting to get some. On occasions we can be flooded by not-to-useful contributions.
This year an “AI statement” is strongly suggested in GSoC proposals. We should do something similar.
There is an ongoing discussion at https://github.com/HSF/hsf.github.io/issues/1919.
Suggestion to update the website how-to with a statement on AI and how we will be dealing with “spam”.
HSF Seminar Series and Compute Accelerator Forum
Planned HSF seminars:
- (skipping May due to CHEP)
- Confirmed seminar on “assessing sustainability of AI” by Sophia Wilson (SAINTS Lab, University of Copenhagen) : 30th Sept
- Invited but to be confirmed:
- via Software Tools & Packaging AA & HEP Packaging Coordination aiming for: “Packaging focused HSF seminar” together with main contributions from EIC & FCC people. - AA conveners working on confirming dates with speakers.
- On “Green Software Engineering” by Michael Sparks, Manchester.
- Inspired by SC4RC conference presentation.
Sapta will follow up on a possible event generators talk.
(Thanks to the activity groups for coming to us with seminar ideas and speakers!) HSF seminar conveners are reachable at hsf-seminar-conveners@googlegroups.com. Please send your suggestions for next seminars.

AOB
Do not hesitate to get in touch with the SG if you have/know of events useful to add to the HSF calendar. The calendar is used by very many to check for available dates, constraints, and plan events. Thank you in advance.
HSF Promotional Poster
Sapta has a poster to promote the HSF. There is one version here, but please contact her for the latest version.
Defunct Repositories
Eduardo noticed a few anachronistic repositories in the HSF GitHub:
- https://github.com/HSF/docker - was intended for homebrew docker containers (for a time hosted the container used for website validation)
- No longer needed, proposal is to delete
- https://github.com/HSF/tools - hosted an HSF C++ project template and a few utility scripts, not actively maintained (there are better maintained alternatives)
- No longer needed, proposal is to archive
If you want to comment or suggest something else, please do so by tomorrow.
Physical Constants / HEPdata Library
There is now an early “proof of concept” version: hep-constants. Some generally positive feedback was received, but no further development yet.
Next Meeting
The next coordination meeting will be on June 4th.
