HSF Weekly Meeting #158, 7 February, 2019

Present/Contributors: Graeme Stewart, Eduardo Rodrigues, Caterina Doglioni, Witek Pokorski, Javier Cervantes Villanueva, Concezio Bozzi, Josh McFayden, Jovan Mitrevski, Margaret Votava, Stefan Roiser, Tanya Levshina

Apologies: Agnieszka Dziurda (Vidyo does not work…)

Google Summer of Code 2019

• See slides attached to the agenda.
• Please subscribe to the mailing list: hep-software-foundation-google-summer-of-code@googlegroups.com.
• To contact the admins, use hsf-gsoc-admin@googlegroups.com.
• If Google accepts us as an organisation (26 February), do we know how many slots we get?
  • Not at that time. We provide, by 25 March, a min/max number of projects we would like to have (this is when students apply to Google with their projects). Google then makes an allocation of slots.

HSF/WLCG/OSG Workshop News and Planning

• Indico - registration is open.
  • 169 people registered now.
  • Early registration ends on 8 February - please register now.
• There is a Google Sheet linked from the main page to help coordinate car sharing from Dulles (you take your own responsibility for this!).
  • If you are arriving/travelling from another airport you can also use that spreadsheet (just make it clear which airport you will be at).

Session Planning (see block timetable)

• Reminder: David Lange, Michel Jouvin and Graeme Stewart organising for HSF.
• General Sessions:
  • Monday, Friday plenary sessions fixed.
  • New Workflows, New Facilities (Tuesday AM).
    • Benedikt Hegner and Maria Girone are convening.
    • Session now planned in concert with Tuesday PM first session
      • See detailed timetable.
• HSF Sessions:
  • Please fill in a first version of your detailed timetable in the coming week, even if not all slots are confirmed.
    • All session convenors have management rights, let us know if you have any problems.
    • And do remember it’s a workshop - schedule generous discussion time!
  • Software on Accelerators (2 slots).
    • Graeme, Michel, David L are convening
      • Confirmed talks on Accelerator Technologies, Framework Integration, Patatrack, ALICE GPU Algorithms, MadGraph on GPUs.
  • Timetable:
    • Analysis and Simulation have their second sessions Thursday AM 9h-10h30.
    • Software Tools moved to Thursday 16h-17h30.
    • Still likely that smaller rooms would be available for any BoFs, but try to let us know ASAP if you want them.
  • Rooms:
    • Monday, Friday plenaries from auditorium can be broadcast, but no Vidyo.
    • Tuesday, Wednesday - HSF parallel sessions in Room F113 which has Vidyo and 100 capacity.
    • Thursday we will need to make some use of the auditorium, which has poor Vidyo.
      • For groups spread between Wednesday and Thursday, try to have the Vidyo critical part on Wednesday.
      • Graeme will check again with Amber what could be done in the auditorium to setup Vidyo for smaller, parallel, sessions.
  • For planning other HSF Parallel Sessions, see WG activity reports below.

Activity and Working Group Updates

General points:

• Reminder to make sure your WG page has:
  • Brief description of the interests of the group.
  • Information on how to join the group’s mailing list.
  • Information on how to contact the convenors (convenor list or individual emails).
  • A link to the group’s Indico category.

Detector Simulation

• Not too much news - agenda for workshop is being prepared, 4/6 talks confirmed.
• Fast Simulation with Machine Learning, 6 March 2019.
  • 3 confirmed talks, 1 pending.

Reconstruction and Software Triggers

• JLab:
  • Confirmed talks: for speakers, see agenda (we will do before tomorrow).
  • Unconfirmed talks: ALICE, CMS (both agreed), LSST (losing hope).
  • Strong request to have Vidyo meetings accessible from outside JLab - how?
    • Currently ok for Reco sessions - F113.
• Meetings:
  • First meeting: had to skip the 6th because of overlap with CMS week.
  • Tentative plan to have the various collaborations discuss trigger systems and then reco software, starting with ATLAS and CMS as they already had this exercise internally, then going two by two (meetings should be limited to 1h30). After this, topical meetings.

Software Tools

• 2 of 3 talks confirmed, Packaging and Static Analysis.

PyHEP

• Skeleton agenda for JLab session up on Indico.
• We are targeting to have the session finalised next week.

Training

• IRIS-HEP meeting this week focused on training.
  • Caterina’s Q: can non-IRIS-HEPpers peek at minutes?
  • Don’t think they have minutes, but instead put the meetings on YouTube.
• IRIS-HEP website has links to mailing lists and Indico.

Event Generators

• We finally have a page on the HSF web site and mailing lists for WG members. Included by default the workshop organisers, then invited all workshop participants, many of whom replied and asked to be included. Please join if interested! See https://hepsoftwarefoundation.org/workinggroups/generators.html
  • We will probably have a first meeting in the next two weeks.
  • Aim to have meetings every other week from then onwards.
• Included the tex sources and latest available pdf of the CWP chapter on the HSF documents GitHub, and linked it from the HSF site. This will not become an arXiv.
• Some (slow) progress on the workshop writeup. We need to advance faster, aim to be ready before a related talk at ACAT.
• In contact with the madgraph team about GPUs. One key team member was absent in the last weeks, but we hope to make more progress now.

Licensing

• Still chasing up CERN KT and FastJet authors.

AOB

• Graeme absent next week - try to get another coordinator to run the meeting.
• (Ongoing) URL checks on website are unreliable; another URL check code could be tried to see if that improves things.
• Working on an update to the instructions for converting Google Doc -> Word -> Markdown.
  • See Andrea’s PR: https://github.com/HSF/hsf.github.io/pull/499
