News, general matters, announcements

Pre-CHEP Workshop

HSF-WLCG pre-CHEP workshop planning now well underway.

See slides on the agenda.

Benedikt: how do we gather outcomes and plan next steps?

Google Summer of Code, 2023

Next steps:

Google Season of Docs, 2023

Google Season of Docs has been announced. Deadline for the application is March 24. We still need to select which project to put forward this time. Proposals welcome.

Still waiting for input!

Valentin - there are projects that would be interested, but perhaps some confusion because only one proposal can be made

LHCC

LHCC Referees Meeting

Graeme presented the Software Project summary to the LHCC (see slides on the agenda). This consisted of inputs from Geant4, ROOT and the 4 LHC experiments.

Projects were present at the meeting with the referees. The LHCC Referees meeting agenda is closed as sometimes sensitive topics are on the slides (hence we mirror the slides on this agenda). Our software slides are public, please use them as needed.

WLCG Half-yearly Report

We have input from the projects and, very soon, from HSF activities which are prepared here.

If you have any comments or observations please make them today or tomorrow (report needs to be submitted on Monday 20).

LHCP Invitation

We have been invited to give a talk at LHCP (May 22-26), in the Upgrade/Performance & Tools parallel session (20’+4’). Tentative title Computing Challenges at the HL-LHC and Beyond. The organisers strongly request in person presence.

We have a volunteer from TMU, Vangelis Kourlitis, who can give this talk (he is an expert on simulation and analysis and we can help with any other aspects of the talk). Thanks to him for volunteering and to Lukas Heinrich for enabling this.

Working Group Updates

General

After we finish all the WG presentations we should update the HSF Planning page, and advertise this and the WG mailing lists to the community.

Meetings

Reminder: Please try and book meetings in Indico at least 2 weeks in advance!

That way they go into the calendar early and they will be included in the weekly email announcement that goes to HSF Forum.

Data Analysis

Software Training

C++ Course and Hands-on Training

The HEP C++ Course, “the Essentials” took place 6 - 10 March https://indico.cern.ch/event/1229412/ at CERN & zoom. The 20 CHF registration fee helped reducing the no-shows. For next time we will free the slots of not paying students on time.

More courses planned in 2023:

Meetings to define more details next week.

Are these courses local or residential? Need to explore resources and rediscuss this.

If you want to stay informed about upcoming courses please sign up at https://indico.cern.ch/e/HepCppInfo. Announcements of new courses will be sent to registrants.

Software Tools and Packaging

Yesterday, presentation and discussion about The status of Linux distributions for HEP.

Detector Simulation

In the process of organizing sessions on:

Reconstruction and Software Trigger

Not much to report. Updated webpage with new conveners’ info. Planning a kickoff meeting (probably next week) with all 3 conveners.

PyHEP

PyHEP.dev 2023 registration is now closed.

Other Interest and Activity Areas

Compute Accelerator Forum

Analysis Facilities

Meeting last week, focussing on EOS storage: https://indico.cern.ch/event/1260978/.

Covered tuning that was done to improve performance to the point where it’s the application which is the bottleneck. And some discussion on user use and abuse of CERNbox. Video is available.

Licensing

Question from the community about providing CUDA on cvmfs (runtime is ok, but SDK is the issue).


AOB

Next Meeting

The next meeting will be on 30 March.

Please sign up for chairing this or one of the future coordination meetings.
