News, general matters
- CernVM Workshop is quite soon, 3-5 June. Please
register:
Google Summer of Code 2019
- Slots requested: min 30 - max 35.
- Accepted slots: 34 (5 more than last year).
- We need to start ranking projects and selecting students.
- 36 projects were eligible, but 1 had no proposals, making 35.
- So had to cut just one project (done based on advisory committee
input - thanks to them).
- Will organise a few meetings one only for mentors and one for
students + mentors.
- Students will be confirmed by 6 May.
- Mentors should not contact students, but can start preparations
for involving the students from May.
- Q. Can you sent a summary to the mentor list?
- Will post a message soon.
Google Season of Docs
- We submitted our application to be an umbrella organisation.
- Three proposals: ROOT, Rucio, DIRAC.
- Google have said they will only give 1-2 writers, but perhaps
different for umbrella organisation, we are asking.
Activity and Working Group Updates
Data Analysis
- Preparing the next two meetings. Indico
links:
- These are clashes with HSF Coordination meeting on Thursdays, not
ideal, but was the best option with other constraints.
- Next week there is also the FNAL workshop on
declarative analysis
languages.
Detector Simulation
- Preparing for next two topical meetings. Indico agendas are now
available. Please don’t hesitate to get in contact with us if
you’d like to suggest any presentations or future topical
meetings.
Reconstruction and Software Triggers
- We had several convenors’ discussions before Easter break, the
outcome is following:
- ATLAS/CMS cross-talks:
- Plan to have meeting on 5th June:
- Topic: Algorithms and data structures to efficiently exploit
many-core architectures - one of the topics described in CWP.
- Invitations to collaborations will be sent shortly.
- We discussed many several potential subjects for our meetings:
- DUNE reconstruction,
- DarkMatter,
- Benchmarking for different architectures (x64, GPU, FPGA),
- SOA vs AOS data format design
- Packages that help go from cuda–>CPU or c++-> GPU
- Organize taster sessions to coding on non-CPU (together with
Training?)
- HLS for FPGA
- GPU programming
- We decided to go through the list and aim to have 1 meeting in
every 3-4 weeks.
PyHEP
Training
- See
slides
attached to today’s agenda.
- Liz is organising a C++ training event at FNAL next month. Good
instructor, but we need to see how well this works for an HEP
audience.
- Feedback from carpentry people who taught at FNAL? Were the
students more advanced?
- They were pre-warned about the level and adapted the material.
- Students were very happy with the course.
- Can we think about a future event in Europe?
- Yes, it’s planned for after the round of current US events.
Event Generators
- Next meeting planned for 9 May.
Event Delivery Forum
Packaging
- Meeting this week was postponed until May.
Frameworks
- Would still like to work on a mandate for a revitalised frameworks
group post-JLab - contact Graeme and Liz if you are interested in
helping.
Workshops
Pre-CHEP (2-3 November)
- First organisation meeting last Tuesday (23 April): only Ian C.,
Michel and Simone. List created for the organizing committee:
wlcg-hsf-workshop-2019-organisation@cern.ch.
Let Michel or Ian C. know if you want to be involved.
- Proposal is to have a 2 x half day meeting from Saturday noon to
Sunday noon so that people can rest a little bit during the
weekend before the CHEP week. Idea is to focus on one topic that
could be of interest for HSF (SW) and WLCG (infrastructure), with
no parallel session. Suggested topic is analysis from DOMA to SW
tools.
- Paul - would have to plan properly, but it’s a good idea.
- Need to distinguish it from the CHEP talks and presentations.
More discussions, break across the site/users boundary.
- TODO: add Andrea and Paul to mailing list.
- Baseline proposal generally supported during the coordination
discussion
- Parallel rooms are available, should people want a BoF or the
like, but in general we don’t want a lot of parallel sessions.
AOB
- Simulation developers have asked for an HSF convened meeting to
present the results of the GeantV prototype and to discuss plans
for the future.
- Proposed datetime is 8 October, 14-18h.
- Noted a clash with a non-CERN ATLAS week
- Would be better the following week (w/b 14 Oct) as any
“clash” with HEPiX should be quite limited.
- Witek will check with colleagues.
- Graeme added the next few WG meetings as announcements to the
website.
- Note we have to have far too many manual steps right now for
meetings:
- Create Indico.
- Add to community calendar.
- Do a PR to the website for a banner via an “announcement”.
- It’s tedious, tricky and error prone - want to improve it.
- Discussion of improvements on
GitHub
(happy to have people help!).
- Next coordination meeting planned for 2 weeks time, 9 May.
