News, general matters, announcements

Letter of Collaboration

After discussion in the coordination group we approved a letter of collaboration with AccelNet-Implementation: HSF-India - Research Software Networks in Physics (description).

The project aims at establishing better collaboration in software with India. We have very good contact with Indian students via GSoC, so there is clearly talent around. Pete noted that few people outside of North America and Europe signed the CWP, so there is scope to expand in many areas of the world.

HL-LHC Review Phase 2

Documents were delivered to the LHCC reviewers on time (1 October). The finished versions have been put into CERNBox. Graeme and Liz wrote a short introduction, that summarises the process.

Many, thanks to the projects and individuals involved.

N.B. The review itself will take place 1-5 November, hybrid at CERN + Zoomlandia. Attendance is being clarified with the LHCC, but it should be possible for some participation beyond document editors.

HSF Letters

After discussion last week, there is a PR to propose a clarification of the HSF policy on letters.


Please comment - plan to merge by end of the week if no blockers.

HSF Upcoming Talks

We have a few HSF talks upcoming:

Draft slides will appear!

Working Group Updates

Mandates for 2022

We should start to think about WG convenerships for 2022

Data Analysis

Productive meeting last week (“kick-off meeting” after summer) https://indico.cern.ch/event/1081616/.

Next meeting will be announced soon.

Detector Simulation

Reconstruction and Software Triggers

No update on 2nd part of the 4D timing reconstruction meeting, will be probably being followed up only next year (LHC community seems very busy with Run-3 preparation).

Further on list for potential topical meetings (following the survey):


Software Tools and Packaging

Software Training

Event Generators

Not much to report, taking a short break after the rush of the LHCC Review document preparation.

Starting to think about topics for future WG meetings. For example, several recent papers of interest:


Continuing discussion with the HepMC3 authors.



The SIDIS COST proposal is advancing well. Contact Graeme and Stefan if you would like to be involved (last chance!).

Anaconda Terms of Service and Licensing

This has changed recently and they are trying to sell it more as a paid for product, not really suitable for our community.

Can we ask Chris Burr about this - he was keen on this as a solution and presented in the HSF Packaging Group. Miniconda provides a lot of addons, but still refers back to the (to be paid for) Anaconda packages.

Still free for individuals, but unclear situation for non-commercial institutions and labs.

conda as a command line tool is still free. “mini-forge” would avoid connecting to the problematic anaconda default channel.

HSF Calendar

As dates start to be fixed for 2022, please add things to the HSF Community Calendar.

ESCAPE + European Open Science Cloud

Setting up the “Test Science Projects”, funded by EOSC-Future grant.

Aim to go from (more or less processed) data to plots, using reproducible workflows that run on common computing resources, using standards/steering tools provided by ESCAPE.

Dark matter TSP, coordinated by Caterina: 4 postdocs started working in different EU institutes in October (CERN / tools, LAPP+Lund+Manchester / ATLAS, LAPTh / Indirect detection & theory, FAU / Indirect detection & neutrinos), 1 to come (INFN Rome 1 / direct detection).

Link: https://projectescape.eu/dark-matter-test-science-project

Also: Extreme Universe TSP.

Would be nice to sync up with what the Analysis WG is doing (e.g. metadata document) –> will contact the conveners after November 2nd when we have the next meeting.

Anyone is welcome to join the meetings if they’d like on the 1st Tuesday of the month at 10 am CERN time, agendas are here: https://indico.in2p3.fr/category/976/.

Next Meeting

Next meeting 28 October.
