News, general matters, announcements
LHCC
There is another meeting with the LHCC referees next week (Tuesday 8). Can WGs please send a short summary of activity and plans to Graeme and Liz by tomorrow?
Draft presentation will be ready on Monday 7.
Workshops in 2022
Analysis Ecosystems Workshop
23-25 May: https://indico.cern.ch/e/aew2
Registration is open! At the moment we have limited this to 80 in-person places.
Thanks to the support of IRIS-HEP, CERN/HSF and IJCLab we do not require a registration fee - coffee/tea and lunches will be covered.
Investigating support for dinner (IRIS-HEP, CERN/HSF, possibly external sponsors), but maximum cost of around €50 per person.
We have a better overview description of the workshop now. Announcement has been sent out to LHC experiments, Belle II, DUNE, EIC, GDB, CERN IT, etc.
Content planning is progressing well, we have session convenors for most of the headline topics:
- Analysis Facilities: Oksana Shadura, Nicole Skidmore
- ML tools and differentiable computing workflows: Lukas Heinrich, Nathan Simpson
- “Real-time” trigger-level analysis: Giulio Eulisse, LHCb mystery guest
- 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 10 March, identifying key questions on the topics - focus on outcomes.
3-6 May: https://indico.cern.ch/e/simgpu
Stub agenda for now (N.B., this meeting is virtual).
Google Summer of Code
HSF call for proposals was sent a few weeks ago. Deadline for project proposals was Feb 25.
We have 39 proposals from 18 projects, covering 25 organisations.
Snowmass
A small team (inc. Graeme and Paul) have helped draft a document with WLCG for submission to Snowmass. The draft should be ready for circulation soon.
HSF History Paper
As reported a few weeks ago, we gave input to Dan Katz re. developing scientific software communities. This summarised the origins and history of the HSF.
The text we wrote is here. It has ended up a very nice summary of our origins, so we would like to publish it. Can people take a look and we shall upload a version of this to Zenodo?
Working Group Updates
General
Data Analysis
- Metadata paper has been submitted to ArXiv
- Email sent to authors with instructions on how to claim paper ownership
Detector Simulation
- Confirming previously scheduled meeting on MARS
- Looking at other meeting ideas
- Contacting DD4Hep developers on possibility of topical status/use meeting
- Also interesting for reconstruction geometry and links between these use cases
- Discussing ML-related topics
Reconstruction and Software Trigger
PyHEP
- We had yesterday the first topical meeting of 2022!
- Topic was histogramming (
boost-histogram and Hist packages).
- See Indico agenda.
- We had a constructive meeting with the conveners of the Frameworks WG last week
- The idea is to host a series of meetings in the upcoming weeks/months on Modern C++
- First invitation was sent today to Axel for a talk on the latest news from the ISO C++ standards and/or reflection
- We also identified a number of additional topics/speakers and will be following up on those soon.
Event Generators
- Snowmass doc for event generators will be circulated within the WG soon.
- WG Meeting next week Thursday at 16:00 with a contribution from Stefan Hoeche on the “Discussion of the Snowmass white paper on event generators”.
- TBA - (invited for 24th March) Recent ATLAS V+jets paper (possibly including related recent Sherpa efficiency improvements).
- TBA - MC4EIC and MCEGs for the EIC
- TBA - MCEGs for neutrino experiments
Frameworks
Software Training
- SW Carpentry + ROOT/uproot training workshop March 28-30, https://indico.cern.ch/event/1112526/, locking in instructors now
- Planning for Matplotlib tutorial in ~April
- Starting to plan an update to HSF Training Survey
- Ongoing weekly meetings on Monday 16 CET
- C++ Fundamentals training 15-17 March, https://indico.cern.ch/event/1119339/
- Anybody interested in upcoming courses please register on the “Waiting List” of this course, we shall send info to the members
Other Interest and Activity Areas
Analysis Facilities
- Activity page live!
- Kick-off meeting arranged for 25 March:
AOB
Calendar
Q. How do we set up the HSF calendar?
- There is a normal Google Calendar, in which any events can be added directly; there is also an Indico sync script that added events from the HSF Indico area, see https://github.com/HSF/merge2gcal (this is far superior to adding things by hand…)
Next Meeting
Next coordination meeting is scheduled for 17 March.
