News

CERN LPCC Monte Carlo Working Group meeting

HSF got invited to contribute to the session “Sustainability of the MC toolchain” with a 15 min presentation. Need to find speaker urgently since the session is precisely a week from today (2 October).

Eduardo has asked Sapta as it would be good to get someone from the HSF event generator group. Andrea Valassi could be a backup.

EPPSU Paper

Status of submission to EPJ C: referee suggested addition of a glossary. TBD asap whether we add it or not.

ACTION: Michel to reply back to the referee consulting with Graeme. The journal have provided proofs already and asked for some technical corrections.

Idea to create a bibtex repository

One often needs to dig out the same references over and over again, be it for HSF workshop proceedings or some software related document/paper.

Eduardo suggests to create a “BiblioHEP” repository and populate with some of the citations content he already has (e.g., the PyHEP 2024.dev 2024 report). Do people think this is a good idea?

Note: doing this was also proposed after the Software Citation Workshop in 2022 (https://indico.cern.ch/event/1211229/), so excellent to finally take some action.

Domain Name

IJClab took over the hepsoftwarefoundation.org domain. This is effectively “infinite” as the lab manages many domain names like this.

ACTION: Michel to have a contact at the lab and pass this on.

Advisory Group Follow-ups

Advertising the HSF

There is an action on Paul and Graeme to follow up w.r.t. advertising the HSF within the collaborations/communities.

We thought it would be good to target the new intake of students in the Autumn.

HSF Budget

The HSF has no funding source but does have a little pot of money from which it receives from the GSoC programme that’s been running for several years. This budget has been used to sponsor for example coffee/tea breaks at training events.

Eduardo has discussed the budget and practicalities with EP-SFT management. We will continue to receive 50% of GSoC stipends and a spreadsheet has been shared with us (via the SG chair) to manage the budget.

For vote: the SG should feel free to use the budget to help meeting costs of in-person events, and also to help with travel expenses, say when the HSF is invited to participate/present in some event, be it a SG member of an AA convener.

For vote: (self-)requests for spends on this HSF budget will be dealt with via the SG chair. The SG will be informed of any request/spend for transparency, and will have the right to veto a request. To make the process as straightforward as possible a SG member will be asked at random to collect the votes (only vetoes are needed, in practice) and inform the chair of the consensus.

HSF Funding Opportunities and Collaboration

Ongoing investigations of a more formal MoU and independent status. Unfortunately no progress since the last meeting.

Change of CERN directorate mean that it would be difficult to make progress until next year anyway. Michel proposes that we have a chat with the future Director for Research and Computing.

Project Affiliation and Affiliated

We have proposed to work with the experiments to compile a list of the software packages that are used. Who wants to make this happen?

Ongoing

ACTION: Eduardo to add the GDoc template to the site to make it easy for everyone to understand the review process in practical terms.

Prospective affiliates

ACTS: from past minutes - since we need to engage ACTS in RSQKit feedback (with a dedicated person helping the implementation of best practices, so it’s not extra work for them), should we do HSF project affiliation in parallel? If yes, send me (CD) the name of the developer who expressed interest + if you’d like to be in cc, and I’ll organise chats that take care of both.

Update (not yet discussed with Graeme): ACTS is happy to be on board, with EVERSE RSQKit editorial board member working with CD (Michael Sparks) doing a first pass “does ACTS satisfy the HSF criteria and what is missing”, then have a discussion in their developers meeting, and then they’ll email the HSF for official evaluation.

HSF representation

WLCG Management Board community software liaison

NTR.

SG Composition

If you know of someone who is active in community work and shares the HSF’s goals consider inviting them to be on the SG.

Follow-up from the WLCG/HSF 2025 Workshop

Recap: should we have a particular focus on Software Sustainability? It is a popular and very relevant topic, with lots of cross-experiment potential. Would it be useful if the HSF were to solicit a mandate from WLCG for this task? It would need to then be expressed as a concrete time-bound task.

Updates from CD on green/sustainable software:

AOB

Connections with other “checklists for software quality”

TLDR: Stefan, CD and Michael Sparks did an exercise of roughly mapping the HSF affiliated project criteria to the ICFA lifecycle panel recommendations and the EVERSE RSQKit tasks. They should all link to each other in some way (how do we do this on our website?).

Full version and insight in this document.

Funding/training matters

Caterina/Eduardo + others from the UK planning to put in a (small funding-wise) UK proposal centered around preparing and collecting material on environmentally sustainable software.

Question to be discussed with Stefan: how to best integrate this in HSF training (using the same infrastructure = TeSS)?

IRIS-HEP update

After a few months of postponements, we will present HSF feedback at the next IRIS-HEP SB meeting on Oct 7th

Presentation needs a dust-off (please help with things that I forgot since July!)

Coordination Meetings

As ever… Chairing sign up document.

C&AF and Seminars

Next Meeting

TBD, as we see fit.
