News, general matters, announcements

Pre-CHEP Workshop

This is pretty much all ready to go now. See indico for final agenda. The Zoom connection is available but this is primarily an in-person event - remote connection should be ok for talks, not so good for discussion.

We plan to circulate the AFF report (it’s almost ready) and a list of topical questions re. heterogeneous resources in advance to that we know what we are trying to achieve. Should be circulated tomorrow.

Google Summer of Code, 2023

Working Group Updates


The planning summary for 2023 is published - thanks to all for input and reviewing.


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.

Event Generators


Still trying to secure talk from CMS re. their adoption of Alpaka. Will start moving onto other topics we wanted to cover this year (e.g. language features, alternatives to TBB).

Compute Accelerator Forum

Had a meeting yesterday, https://indico.cern.ch/event/1264290/:

Next meeting is post-CHEP, 14 June, on HEPIX Benchmarking Project, Domenico Giordano (CERN) - including how to benchmark GPU and other accelerated workloads.

Conditions Databases

A draft of the long-awaited conditions DB use cases, workflows and requirements document will be discussed at a meeting next Tuesday afternoon at CERN. The reference implementation that will be presented at CHEP will also be discussed during the meeting.



Benedikt started an issue in GitHub to gather ideas about reorganising and revamping the website to better reflect our areas of actual activity.

Next Meeting

The next meeting will be after CHEP, on 25 May. (11 May meeting is cancelled.)

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