News, general matters, announcements
HL-LHC Review Phase 2
Now very close to the draft documents being released on 30 June - we hope that people can free some time to read and comment.
DUNE Framework Requirements Review
We have begun writing up the final document that will be presented to DUNE. To aid our write-up, there have been subsequent emails (and offline discussions) with DUNE to get some clarification on their memory requirements.
Still targeting completion by end of June or shortly thereafter.
HSF Domain Name
Still investigating this with CERN, who might want to take it over connected with the lab’s Jekyll deployment.
Working Group Updates
Data Analysis
Analysis in the wider HEP/nuclear physics community:
Analysis metadata document:
- Received lots of excellent feedback, which we are implementing now
- Plan to post the finished document on Zenodo and the HSF website; should we also consider publishing it in a journal? Best candidate is probably Computing and Software for Big Science.
Detector Simulation
Will resume meetings in late September/early October.
Several topics planned to be covered, including MARS, varying Geant4 model parameters, DD4HEP, GPU developments update.
Reconstruction and Software Triggers
PyHEP
- No topical meeting until September (breaks are good and important, especially these days).
- PyHEP 2021 workshop:
- Starts in 2-ish weeks on July 5th.
- Abstracts review done. Final agenda soon to appear on Indico.
Software Training
HEP Software Training Challenge
- Date–>Monday 28 June 2021
- Time –> 4:00 PM-6:30 PM CERN time
- Indico –> https://indico.cern.ch/event/1044523/
- Goal–> In this workshop we propose to build on and expand the software training effort in the coming 3 years by defining a clear target in the form of the “Training Challenge”.
HSF Training Hackathon on C++
- Date: Monday 5 July 2021
- Time–> 4:00PM -6:30 PM CERN time
- Indico –> https://indico.cern.ch/event/1044512/
- Goal–>This would focus on revisiting highly successful and sought after C++ training, lessons learnt, progress made, modifications needed and feedback to constantly improve it.
HEP C++ Course
- Preparing for 3rd iteration of the event. Plan to hold the course 30 Aug - 3 Sept https://indico.cern.ch/event/1019089/
- Registration for 75 places will open Monday 28 June, 9 am CEST. (if you are interested please be there on time, last course was “sold out” in a bit more than 2 Minutes)
- Currently we are working on adapting content and new exercises.
- IMPORTANT: We are looking for mentors for the hands-on tutorials. A mentor would usually attend 2 hands-on trainings (2 hours each) during the week and guide 5 - 10 students through already prepared exercises. Please contact the organizers.
Event Generators
- Meeting last week about Herwig. Meeting later today about Powheg and LHAPDF/Rivet. This probably completes our meetings before the summer. We started to ramp up rapidly on the preparation of the LHCC document (quite late with that).
- For now Pythia8 is most advanced but still incomplete.
- Andrea: the vCHEP proceedings on the work on MG5aMC on GPU and vector CPUs will be on arxiv tomorrow.
- LHC Top WG had a contribution on studies towards a common MC sample for ttbar events.
- Main focus not initially for sample sharing
- But they are using HSF EOS space to store LHE files as part of the process.
Frameworks
- Nothing to report in addition to DUNE framework-requirements review.

Next Meeting(s)
Our next meeting will be 8 July.
