Workshops in 2022
Analysis Ecosystems Workshop
23-25 May: https://indico.cern.ch/e/aew2
Registration is open! (limited this to 80 in-person places).
2022-03-31: 50 people have registered, mostly in person
Progress is being made by session conveners on the following topics:
- Analysis Facilities: Oksana Shadura, Nicole Skidmore
- ML tools and differentiable computing workflows: Lukas Heinrich, Nathan Simpson
- We need to chase this one up!
- “Real-time” online/trigger-level analysis: Giulio Eulisse, Mike Sokoloff
- Analysis User Experience and Declarative Languages: Jonas Rembser, Alex Held
- Analysis on reduced formats or specialist inputs: Allie Hall, +others
- Bookkeeping and systematics handling: TJ Khoo, Paul Laycock
Next organising meeting 7 April with the goal to have a draft agenda ready
- Requires all sessions to have a precise enough idea to make it possible
Please forward news about the workshop to your community and think about key people to invite.
- HSF Detector Simulation on GPU Community Meeting to be held 3-6 May
Google Summer of Code / Season of Docs
GSoC evaluation period finishes this weekend, 3 April.
GSoD, proposal has been made and advertised, combining documentation sub-projects for Clang-REPL, Rivet and Gambit - thanks to David and Andy for doing this.
HSF History Paper
Document. Upload to Zenodo is still TODO! Document should first be converted to LaTeX to make it look nice for posterity.
Graeme and Alessandra gave talks at the SWIFT-HEP workshop last week - thanks for comments and improvements.
Working Group Updates
- Final modifications to Metadata paper ongoing - will re-circulate to proponents
- Discussing having a meeting on the 12th April focussing on Systematics
- Held a meeting on MARS: https://indico.cern.ch/event/1107097/
- Next meeting will be on Fast Calorimeter Simulation Challenge on April 11th
- HSF Detector Simulation on GPU Community Meeting (3-6 May) - see above
- Expecting a session on DD4hep towards the end of May
Reconstruction and Software Trigger
- Second meeting on 4D reconstruction held on 16/03/2022, agenda at https://indico.cern.ch/event/1128087/.
- Preparation ongoing on ML in Reconstruction topical meeting (after IPa Workshop, Orsay, Paris), tentatively end of May.

- Next topical meeting on “Awkward Array (and ‘relatives’) Updates”. Agenda at https://indico.cern.ch/event/1140031/.
- PyHEP 2022 workshop will be taking place on the week of September 12th! Event is on the HSF community calendar. Agenda to be out soon and advertised. Do book that week if interested :-)!
- 10th March: Snowmass Generators Whitepaper
- 24th March: ATLAS V+jets - was very interesting, lots of discussion!
- 7th April: Further Sherpa efficiency improvements by Enrico Bothmann (confirmed)
- 5th May: Neutrino event generators (confirmed)
- 2 June: Master thesis on chirality flow formalism (TBC)
- 23 June: EIC/NP Generators usage (TBC)
- 7th July: Event generation with Julia (confirmed)
- 1st Sept.: AI/ML-focussed discussion (TBC)
Interesting presentations at Swift-HEP workshop relating to generators, one half of this (Sherpa) will also be presented at our 7th April meeting.
- To avoid colliding with the PyHEP topical meeting on 6 April, we have rescheduled our next meeting for 13 April at 15h30.
- After our 4 May meeting, We will be shifting our regular meetings to the last Wednesday of each month.
- Software Carpentry workshop held on 28-30 of March (link to Indico).
- 58 participants registered. ~30 participants attended live.
- Carpentries instructors covering the basics (Bash, Git, Python)
- HEP community instructors for ROOT (E. Saavedra, V. Padulano and J. Rembser) and Uproot (J. Pivarski).
- We will discuss the pre and post surveys and the aftermath in the next HSF Training meeting on Monday.
- Next event is Matplotlib Training (link to Indico).
- This is the first Matplotlib event organized by the HSF Training community. Material preparation is almost done.
- Pending: surveys, prerequisites.
- Registration is open. 14 participants registered so far.
Other Interest and Activity Areas
- Kickoff meeting took place last week
- Up to 67 attendees at the peak (note this was 1500-2000 CET), lots of very good discussion
- First topical meeting scheduled for the 14th April 1800-1900 CET on the use of Kubernetes. Meetings then bi-weekly. Yet to be widely announced
Benedikt contacted all HepMC3 authors for consent to move to LGPLv2.1-or-later instead of GPLv3. All but one answered and agreed. One objection, but not clear that this person actually contributed any code, so this may be a moot point.
Finally having the first meeting next week, Wednesday April 6th: https://indico.cern.ch/event/1143958/.
We could delay the start time to 14:30 to be kinder to our US colleagues, and Graeme seems to have pre-empted this :)
After deciding that Fermilab would not be considered as non-commercial, which led to a block on access to the Anaconda repositories being put in place at Fermilab and to a rash of PRs to make sure that there were alternatives, Anaconda seem to have changed their mind on this. Fermilab is still considering how to react.
HSF Mail in Spam?
Graeme put in a ticket with CERN about HSF email being mischaracterised as spam, which seems to have been a problem in the last few months. (There is little/no actual spam from HSF lists.)
Next coordination meeting is scheduled for 14 April.
