News, general matters

• We have been asked by the INDIGO-Next project to provide a letter of support for their proposal.
  • Project initiated many useful developments in distributed computing - analysis capture and preservation.
  • Draft Letter was approved by the meeting.
• CERN Computing Seminar next week is interesting Hardware acceleration with GPUs and FPGAs (speaker from Oracle), Tuesday 29 January, 16h CERN time.
  • No Vidyo, but recording usually posted after the event.

Google Summer of Code 2019

• Remember the HSF deadline: February 4.
• Presentation last week had all the details.

HSF/WLCG/OSG Workshop News and Planning

• Indico - registration is open.
  • Early registration ends on 1 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:
  • Opening plenary session from HEP experiments and other communities (Monday)
    • Confirmed talks from LHC Experiments, DUNE, Belle II, Dark Matter, Electron-Ion Consortium, LIGO, IceCube; yet to confirm LSST, Lightsources.
    • Plus discussion on WLCG future evolution.
  • Closing Session, visionary talk and discussion on the future (Friday).
    • We will also hear about funding news from various projects - important to have a community coordinated approach.
      • DE (Thomas Kuhr)
      • UK, IRIS (Pete Clarke)
      • US, IRIS-HEP (Pete Elmer)
      • If you are aware of any other projects that have secured funding for software efforts can you let us know?
    • Amber Boehnlein has agreed to do the final talk.
• HSF Sessions:
  • Please fill in a first version of your detailed timetable in the coming week, even if not all slots are confirmed.
    • And do remember it’s a workshop - schedule generous discussion time!
  • Software on Accelerators.
    • Graeme, Michel, David L are convening
      • Confirmed talks on Accelerator Technologies, Framework Integration, Patatrack, ALICE GPU Algorithms, MadGraph on GPUs
      • Still a number of other possible topics to follow-up and confirm.
  • For other HSF Parallel Sessions, see WG activity reports below.
  • One spillover BoF slot, Thursday late PM.
    • Logistics of the Wednesday afternoon 3-way split might entail moving some sessions to this slot.

Activity and Working Group Updates

General points:

• hsf-wg-convenors list can now edit the HSF community calendar to add their meetings.
• Reminder:
  • Please set up mailing lists and advertise them on your group page.

Data Analysis

• Kickoff meeting yesterday. Lot of good inputs being now processed. Next step on Feb 13th more focused on existing technologies and ideas in development for data analysis.
• JLAB WS agenda still to be discussed.

Detector Simulation

• Topical meeting next week - Fast sim from the LHC experiments.
• 6 March Machine Learning flavour.
• Workshop - sending invitations, 6 talks planned and speakers invited.

Reconstruction and Software Triggers

• In each session we aim to have:
  • 15 min + 5 min -> 4 talks + 10 min for general discussion.
• Contacted several potential speakers for HSF/WCLG/OSG workshop:
  • A comprehensive real-time analysis model at the LHCb experiment (waiting for the final confirmation).
  • Similar “real-time analysis” request soon to be sent to ATLAS/CMS.
    • We have tentative speakers, then speakers committees will decide.
  • Using FPGAs to accelerate machine learning inference (confirmed).
  • ML in industry: forecasting traffic by Ximantis (waiting for the final confirmation).
  • Expand possibility of having talks from ALICE O2, DUNE track/reco, Belle II mails sent out, waiting for response.
  • We already received other proposals - to be discussed among convenors.
• We aim to have a kickoff Reco&Trigger meeting on 6th Feb.
  • Introduction to the WG.
  • Open call for contributions.
  • Thematic meetings to come later.
• Ongoing activity: We try to get a wide input/feedback about the needs from the HEP community: discussions with trigger/reco responsible people among experiments.

Software Tools

• We aim to have three main topics : monitoring/profiling tools, static analyzers, and packaging.
• Looking for ~3 talks (i.e. one on each subject) w/ 50% talk 50% discussion.
• Solicited input from the community via e-mail. Can possibly accommodate a few lightning talks if there is any interest.

PyHEP

• Workshop session at JLab workshop:
  • Skeleton agenda finalised - lightning talks and 2 topical talks.
  • 1 lightning talk confirmed.
  • As for the rest: invitations out or about to go out.
  • Still have space for 1-2 lightning talks. Do get in touch!

Licensing

• FastJet authors contacted again.
• CERN KT were contacted to properly establish a procedure for relicensing code that is copyrighted to CERN (in particular, Gaudi).

Packaging

• Next meeting scheduled for 30 January.

Software Forum

• Reminder: we have the forum slot Wednesday 17-18h CERN time every odd week (13 February + N * 2 weeks).
  • Available for any HSF meetings
• With the new working groups starting some activity has moved out of the ‘general’ session.
  • However, for presentations on general problems, solutions and links to other sciences this still has relevance.
