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: 61 people have registered, 50 in-person

Do think about key people to invite.

Detector Simulation on GPU Community Meeting

Google Summer of Code / Season of Docs

GSoC proposal period ends 19 April (not much time left!).

HSF History Paper

The History Paper has been converted to LaTeX and uploaded to overleaf.

References need to be redone properly, but the text should be fine.

Ask Graeme if you want to help (to get the editing link).

Authorship - propose to name those who helped write the paper, then “for the HSF”.

Talks

Graeme will give a talk on “Software Frameworks” in the JENAS meeting in Madrid 3-8 May (“frameworks” to be interpreted broadly as the whole data processing pipeline). Would like to highlight multi-experiment projects (like ACTS) and adaption to heterogeneous hardware (like Allen) as broad themes.

Meeting is primarily European, but see ICFA point below.

Draft slides will appear next week…

Working Group Updates

Data Analysis

Detector Simulation

Reconstruction and Software Trigger

PyHEP

Software Tools and Packaging

No substantial update yet. We are still arranging a time for our next meeting; we discussing times with speakers for an update from a long-ago ACTS talk, concentrating on build time and monitoring.

Frameworks

Our speaker for yesterday (13 April) had to reschedule for 25 May. The next meetings will be:

Software Training

Other Interest and Activity Areas

Licensing

We have all but concluded on the HepMC3 re-licensing - time for the PR…

Conditions Databases

The first meeting of the activity went ahead last week: https://indico.cern.ch/event/1143958/

The idea of the meeting was to first see if we could agree on the definition of the problem(s) we are trying to solve, looking at workflows and use cases. Very encouraging that we seemed to have consensus in the meeting, so there doesn’t seem to be a pressing need to discuss “what we missed”. A preliminary strawman (and incomplete) list of requirements was discussed to kick off discussions. Again we had encouraging consensus and positive contributions. The idea is to now move on and write this up, i.e. attempt to write a short white paper defining the use cases and requirements.

AOB

Computing Training Mentors Request

We have been contacted by Igor Slazyk about a Norwegian summer school which will be held from 26 June to 8 July. They are looking for people to help with their hands-on computing tutorial on 1 July in the IT Auditorium. There seem to be no set exercises, but general help with Python and ML and data analysis is likely to be something the students want to do.

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.)

CERN IT have been active in trying to help with this, which relies on understanding why emails forwarded from users are not landing in the anti-spam training dashboard. However, Microsoft support seems a bit lacking for now…

In the meantime we recommend:

Software in ICFA

A few people discussed with the ICFA secretary about software in the context of the ICFA. In the last panel meeting it was agreed to go forward with a little discussion round with representatives across the field. The discussion should take place before the next ICFA meeting.

Next Meeting

Next coordination meeting is scheduled for 28 April.
