News, general matters, announcements

HSF Joint Workshop with WLCG

Registration is now open for the WCLG-HSF workshop at DESY (13-17 May) is now available: https://indico.cern.ch/e/wlcg-hsf-2024 (register at the DESY linked Indico)

Graeme, Eduardo and Caterina are helping with the overall organisation for HSF.

We would like to have a few dedicated sessions/talks:

Our main HSF activity will, however, refocus on community software. We have opened a call for abstracts:

The HSF will have several sessions on Community Software at the workshop. We invite you to submit abstracts for talks of 20’ where you can describe a tool, package or other contribution that you are making to software for multiple HEP experiments. Submissions describing projects or other ideas, such as training initiatives or community support structures are also warmly welcomed. This is your chance to show off how good your project is and to meet and talk to current and future users!

Please broadcast this call widely and encourage contributors. Deadline is 18 March.

If any WG wants to organise a focus session, let us know ASAP (next week)! Block timetable (also for WLCG) will appear soon.

LHCC in February and RRB Report

This is next week, Eduardo prepared a slide for PyHEP.dev (attached to the last meeting).

Eduardo has also drafted the HSF section of the RRB report. Please contribute and comment by Monday 19 February.

(RRB -> Resource Review Board; review experiment resource requests, but the board now also takes an interest in software and staffing levels)

Google Summer of Code 2024

Deadline for project proposals passed. We got in total 22 proposals and are now waiting for Google to announce the participating organizations and their quotas.

HSF Evolution

The HSF Core Coordination Team has met a few times since the beginning of the year, thinking about how we (re)organise the HSF to be as effective as possible in our next decade.

We have now decided to work on specific proposals along the following lines:

We should have more news soon on developing these ideas.

Working Group Updates

General Standing Reminders

Conveners for 2024

The convener teams for 2024 are now complete!

New full list of conveners who are joining is:

Many thanks to them, to our continuing conveners and to our outgoing colleagues 👏.

We have a good diversity in regions (thought AP is still weak), experiments and nuclear/HEP.

Data Analysis

See slides on indico.

Re. analysis facilities, LHCC had expressed some concerns about the differences in assumptions and had asked the experiments about their requirements. This is still being followed-up.

Work with Tools WG on optimisation would be a common area of interest - show people how to better use the profiling tools which are available.

Work on statistics, linking theory to practical tools would be another idea for activity that could work for DAWG.

LHC Reinterpretation Forum has people who could be interested in DAWG work, if the right connections can be made.

Detector Simulation

Software Training

Plans for 2024 are on Indico.

Name of Analysis Pipelines might be confusing (or at least unexpected).

Paying people to teach is logistically very complicated.

C++ Course and Hands-on Training

Postponed contributions

Due to time constrains the following points were not discussed and postponed to the next meeting

Reconstruction and Software Trigger

PyHEP

See slides on the agenda.

JuliaHEP

Other Interest and Activity Areas

Analysis Facilities

The Analysis Facilities Forum Whitepaper is now revised and finalised. An email will be circulated soon to advertise the report and to ask for endorsements.

Huge thanks to the AFF team (Alessandra, Nicole, Lukas and Diego) for all the work they put into the AFF over the last two years!

Compute and Accelerator Forum

We are planning and actively inviting speakers for the rest of 2024 - there are still slots left!

Software and Computing Roundtable

Plans to restart in March.

AOB

CERN Mail filtering

We had issues again this week with HSF mail being quarantined by the CERN mail filters (xorlabs). This was due to Google Group’s propensity to spoof sender addresses (see this article. HSF Forum, WG Convener and Coordination lists are now whitelisted. We are discussing if we can fix this also on the group settings, changing the Default sender to Group Address.

If you have other Google Groups you use, please watch out for this!

Next Meetings

The next meeting will be on 29 February.

Reminder: please sign up for chairing one of the 2024 meetings.
