News, general matters, announcements
European Strategy Update (ESPPU)
We have had four of the meetings to gather inputs with the community:
- Detector simulation
- Reconstruction and Software Triggers
- Training and Careers
- Generators (met on Nov 15th)
Data Analysis group meeting will be Dec. 16, announcement to follow shortly.
Should we make a specific call for further inputs now? Contact conveners?
- Yes.
Contact made with all the LHC experiments plus DUNE and Belle II. Generally they seem well disposed to signing the document.
Preparing the Draft
Schedule is to have a draft ready in January. Because of the extra time needed by the experiments to endorse, we would like to target 17 January for this to be ready.
Suggestion: as we expect a lot of activity in terms of comments we begin this as a Google Doc. (The intention would be to finalise as LaTeX.)
- Agreed on both points.
HSF Seminar Series and Compute Accelerator Forum
Seminar Indico Category. Compute & Accelerator Forum Category
Third HSF seminar took place last week: Event Generation on GPUs
Next scheduled seminar dates are:
- 29 January: no topic identified yet, any volunteer?
- Sapta: Future colliders (including Key4Hep, 1 detector)
- 19 February: Verrou, floating point stability check
- 26 February: 4D reconstruction
- 26 March: EPPSU
Other experiments? Einstein telescope / GW Low Latency analysis ? Can discuss with Paul.
We are discussing how to optimise organisation of the events - concrete proposal to follo after an SG discussion.
Advisory Group
Date of the first AG meeting is not yet set. Graeme will send around a Newdle before the end of the year (target end of January). Setting up mailing list now.
HSF Affiliated Projects and Software
We need to find people to help do these reviews. They are fairly lightweight and should not take a lot of time - we are checking usefulness and impact in the community, as well as software development and project best practices.
The NNPDF collaboration asked more than a month ago to be included - discussions with generator conveners to find an additional reviewer.
We should also start to approach our previous projects. Volunteers?
Todo: add on the HSF site a page with the list of affiliated projects.
Activity Updates
Thanks for people who have made their intentions clear, either to stay on or step down.
We anticipate calls for new conveners in most groups: Data Analysis, Simulation, PyHEP, Reco and SW Triggers, Dev Tools and Packaging, Training, Physics Generators. JuliaHEP is TBD.
We are now seeking nominations for these groups. Please contact hsf-search-committee@cern.ch (currently Benedikt, Claire, Michel, Liz, Graeme, and Paul).
Data Analysis
Announcement for Dec 16 ESPPU to follow shortly: agenda
Software Training
We are planning activities for next year, including training events and hackathons, and we hope to have a complete plan by the end of the year-beginning of January
HSF/IRIS-HEP Software Basics Training - June 18-20, 2025, at CERN
A date for the 12th HEP C++ Course and Hands-on Training - The Essentials has been set for the week 10-14 March.
Software Tools and Packaging
Nothing to report.
Detector Simulation
- Sent a reminder to provide ESSPU input in addition to the one provided at the November 22nd meeting;
- Next step would be to start drafting the main points and the text
- Geant4 Technical Forum to be held on December 12th
Reconstruction and Software Trigger
- Had excellent speakers giving excellent talks.
- Recording available - see agenda (glad we recorded it in the end!)
- Attendance was ~35 people(?) (varied as long 3-hour session). Roughly 50/50 split between ATLAS & LHCb with ~1-2 from CMS, ALICE, ePIC (but key people, e.g. computing coordinators amongst them).
- No one from DUNE & Belle II (we believe?).
- Tried to summarise the main messages and discussion points, see here!
- Also advertised beforehand and during meeting Google doc for community input, in particular as not much time for discussion. But doc mostly only used by us (convenors).
- Quick thoughts on some topics that may have not been covered:
- Offline computing: In particular challenges of hetereogenous computing technologies? Main focus was all around trigger, with exception of 4D reco.
- Energy sustainability: Natural common thread throughout all topics though - is this something we can address generally in the HSF document?
- No problem to add a paragraph on this that may be moved in a common section
- Graeme: wider issue of environmental sustainability, it’s not just CO2
PyHEP
The report to the PSF concerning the sponsorship for the PyHEP 2024 workshop was submitted last week.
Physics Generators
Work done related to ESPPU
JuliaHEP
We are starting to plan the JuliaHEP 2025 workshop.
AOB
Next Meeting
Next meeting will be 16 January
- Meeting planned on December 19 is cancelled
- ESSPU work progress will be followed up by email
2025 Meetings
Coordination meeting slots have been booked for 2025 - the usual pattern every two weeks on odd weeks of the year. The first meeting next year will be on 16 January 2025.
Reminder: please sign up for chairing this or one of the future coordination meetings - including 2025!
