News, general matters, announcements

Pre-CHEP Workshop


Confirmed with WLCG colleagues and LHC computing coordinators the two topics for a pre-CHEP workshop on 6-7 May 2023 in Norfolk, VA.

The scientific organising team are working on planning the event now (Ofer Rind, Alessandra Forti, Pepe Molina, Nicole Skidmore, Lukas Heinrich, Alexander Held, Diego Ciangottini; collectively hsf-wlcg-2023-workshop@cern.ch).

Aim for a progress report next meeting

Google Summer of Code, 2023

Our application has been submitted based on 25 projects (compared to 40 last year!). Now waiting for the announcement by Google about accepted organizations (Feb 22).

No computing infrastructure projects this year - these were the projects that had poor success last year.

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.

It is possible to fold a few topics into one project, if that is optimal (as we did in 2022).


Liz and Graeme were in discussions with the LHCC Referees (and the LHC Computing Coordinators) and we decided that we will focus on common software projects w.r.t. progress since the LHCC HL-LHC review.

The referees also indicated they would like to focus on Analysis Facilities in June, which is excellent timing given the pre-CHEP workshop.

The WLCG 6-monthly report is due for 20 March. Liz and Graeme can prepare 1/2 page on HSF activities, but if you would like us to highlight anything in particular, please let us know. (Ref: inputs from 2022H2.)

Working Group Updates


We still have one open convener position for the Reconstruction and Software Trigger WG. Please let us (Liz, Michel, Benedikt, Graeme) know if you would be interested or would like to make a nomination here.

We shall now remove outgoing conveners from the mailing list - thank you again for your contributions!

Can working groups please submit a website pull request, updating their conveners (you can also think about updated group text).


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

See slides on the agenda…

Next step, organise a meeting to start this process, with a follow-up at CHEP.

Software Training

C++ Course and Hands-on Training

New HEP C++ Course, “the Essentials” planned for 6 - 10 March https://indico.cern.ch/event/1229412/ at CERN & zoom. Registration opened Monday 6 Feb 9h. 82/100 places are booked (N.B. this time there is a 20CHF registration fee).

If you want to mentor please contact stefan.roiser@cern.ch

More courses planned in 2023:

Would be nice to confirm these dates properly!

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

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