HSF/WLCG/OSG Workshop News and Planning

• Indico - registration is open; 40 people signed up at the moment
  • Please sign up quickly for planning (and early registration, up to 1 Feb)
  • Car sharing from Dulles - common organisation? It’s a complicated problem, but no harm in starting a spreadsheet.

  • Opening plenary session from HEP experiments and other communities (Monday)
    • Future plans, emphasis on areas for common R&D and tools.
  • Technology watch and networking (Tuesday AM).
  • New Workflows, New Facilities (Tuesday AM).
  • Closing Session, visionary talk and discussion on the future (Friday).
• HSF Sessions:
  • Software on Accelerators (2 slots).
    • Graeme, Michel, David L will convener; send suggestions (generators, tracking, etc. style projects)
  • Simulation (2 slots, with one in parallel with other HSF sessions; idea is to use first slot for topics of general interest, second for items that are more technical or narrow in focus)
  • Reconstruction (2 slots, 1 “parallel”)
  • Analysis (2 slots, 1 “parallel”)
  • Software Tools (1 slot)
  • Education and Training (1 slot)
  • PyHEP (1 slot)
  • One spillover BoF slot
• We ask groups to report on their session planning next week.

Activity and Working Group Updates

General points:

• Please set up mailing lists and have them added to the mailing list page.
• We can help with website practicalities.
• For the first announcement of new group’s activities you can send an email to the whole HSF using the hsf-forum list (any subscriber can post).

Detector Simulation

• Meeting before Christmas.
• Draft list of topics for the workshop - will start looking for speakers now.
  • Will have topical talks, not experiment focused.
• Email sent to the community this week on meetings and activities.
• Planning topical meetings
  • 30 January is first meeting on Fast Simulation.
  • 6 March - also Fast Simulation.

Reconstruction and Software Triggers

• Will resume work on January 15th when we’re all back.
  • Priority will be workshop topics/speakers (given deadline of Feb 1st).
• Planning to have informal talks with ATLAS community during the last week of January (P&P week) - goal: understand how this WG could be useful (how the community/conveners of trigger and reconstruction see it).

Event Generators

• Workshop proceedings being prepared.

Quantum Computing

• WG page is a PR in the website repo.

Licensing

• ATLAS have open sourced their Athena repository, under as “Apache 2 license, except where other licenses apply”.
• CMS are doing the same on Monday.
• Good opportunity to re-discuss with the FastJet authors, which affects around 20% of Athena (turning it GPL).

Packaging

• Next meeting end of the month.

PyHEP

• Planning workshop session.

CWP

General Matters and Roadmap

• CWP Roadmap was accepted by Springer for CSBS.
  • CERN agreed to pay the Open Access fee.

Publication status for Individual WG Papers

• Event/Data Processing Frameworks
  • Done! https://arxiv.org/abs/1812.07861.

AOB

• Propose to organize the “Latin American Workshop on S&C Challenges in HEP” under the umbrella of HSF in Mexico.
  • 3 days workshop involving the LA institutes. Tentative dates November 20-22
  • The goal is to explore and consolidate new partnership opportunities between Latin American institutions in S&C research within HEP. It includes strengthening existing collaborative efforts of Latin American groups with international HEP laboratories and identifying future research interests in common.
